| Protein Extraction Buffer (PEB) is an extraction buffer for the disruption and solubilization of total protein from plant tissues and algal cells. The buffer contains the anionic detergent LDS, which does not form crystals while stored at 4-10°C, and is quickly ready to use. Expected yields will be 1.5-6 µg/µl total protein (recovered from standard procedure), depending on the starting material, e.g. its biological stage and homogenization method used (bead beater vs. sonication). For processing of multiple samples, simultaneous extraction using for example a bead beater is recommended, for consistency of extraction. Provided as 5 x 2 ml (4x stock), Agrisera's PEB buffer allows up to 75 isolations of plant material (using 500 μl 1x PEB for 100 mg fresh weight), or 190 isolations of algal material (using 200 μl 1x PEB for cell amounts corresponding to 4-10 μg total chlorophyll).

| Anti-PsbO antibodies, product number: AS06 142-33, detect a PsbO protein in a wide range of different species. Recently, reactivity on a new species, Eucalyptus grandis, has been experimentally confirmed using the following protocol: 13.5 µg/well of total protein extracted freshly from Eucalyptus sp. leaves. Exact buffer components were: 50 mM HEPES NaOH pH 8.0, 5mM DTT, 15 mM NaHCO3, 20 mM MgCl2, 2 mM EDTA, 4% (v/v) EDTA- free protease inhibitor cocktail (Roche Diagnostics), 4% PVPP (w/v), 20% glycerol (v/v), 1:1 Tris-buffered phenol (v/v) and 100 mM CH3COONa in methanol. Extracts were denatured with SDS beta-Mercaptoethanol sample buffer for 10 min at 90°C. Samples were separated at RT on 12% SDS-PAGE and blotted for 1 h to PVDF, using wet transfer at room temperature (RT). Blot was blocked with 5% non-fat milk for 1 h at RT with agitation. Blot was incubated in the primary antibody at a dilution of 1:5000 for 1 h at RT with agitation in TBS-T. The antibody solution was decanted, and the blot was rinsed briefly twice, then washed three times for 10 min with TBS-T at RT with agitation. Blot was incubated in matching secondary antibody (anti-rabbit IgG HRP, Agrisera AS09 602) diluted to 1: 10000 in TBS-T for 1 h at RT with agitation. The blot was washed as above and developed with a following chemiluminescent detection reagent. Exposure time was 12 min. |  Samples: 1: 13.5 µg of Eucalyptus grandis whole leaf extract clone one (g1) |
With millions of antibodies offered worldwide, by hundreds of suppliers, it may be a bit overwhelming, especially for beginners, to choose the correct antibody to answer a specific questions in a research project. Here is a short checklist with what to pay attention to: Species reactivity – Has the antibody been used to detect the protein from the species we are working with? If not, a request should be sent to the supplier to confirm if the antibody may have so-called predicted reactivity to the target protein. If not, the antibody is not suitable, and false positive results can be produced. Validation data – Is validation data available on a product information sheet? For non-essential proteins, validation data should include results obtained with knockdown or knockout mutants. Western blot results showing that an antibody binds to a recombinant protein, are not relevant to the binding in a specific sample, extracted from a specific tissue or organism. Here we explain why. Recommended antibody dilution – The lower the dilution, the fewer tests can be conducted using an antibody. Here we explain why. Publication record – Being citet in scientific articles definitely confirms the performance of a given antibody. However, as there is no worldwide standard, product numbers are oftentimes not included in the "Material and Method" section. This makes it difficult to identify what antibody has been used to obtain the presented results. How to cite antibodies in scientific publication, is explained in this short video. |  You are always welcome to contact us with any questions, and we will promplty help you to find the best antibody for your specific species and application. |

Agrisera supports protein detection in your laboratory with tailored reagents with the following features:
For chemiluminescent detection of the activity of HRP (Horseradish Peroxidase enzyme), coupled to a secondary antibody, we recommend using: AgriseraECL Bright (AS16 ECL-N), for low pico to mid-femtogram detection (for proteins of medium and high expression), or the enhanced AgriseraECL SuperBright (AS16 ECL-S), for extreme low femtogram detection (for proteins of low expression). Both reagents are provided in one set and if one of ECL is not sensitive enough, or there is too much background, the membrane can be washed and developed again, as described here. For laboratories without a CCD camera, visualization of the target protein can be made using so-called chromogenic detection with Agrisera BCIP/NBT ALP Substrate (AS19 BCIP-NBT) or Agrisera BCIP/NBT Plus ALP Substrate solution (AS19 BCIP-NBT-PLUS). In this case, the secondary antibody is conjugated to an enzyme called ALP (Alkaline Phosphatase). The reaction is visualized directly on the membrane through color development, and the membrane can be stored in the lab book for a future reference. This detection system is not appropriate for proteins of low expression, or to detect protein modifications, such as phosphorylation. |  |
The 20th Scientific Conference of the Phycological Section of the German Botanical Society took place between 12th and 15th of March in Jena, Germany. The talks covered various aspects of algal biology, including biotic interactions, algal ecology, perception of abiotic factors, applied phycology, algal physiology and algal tool box. Agrisera supported the conference with The Best Poster Prize and free copies of Agrisera's Educational Posters, focused on photosynthesis. |  |
| Agrisera secondary antibodies, conjugated to HRP (Horseradish peroxidase) and ALP (Alkaline phosphatase) enzymes, are high-performance antibodies that can be used in high dilution, up to 1: 100 000. This means that 1 mg of a given antibody will allow quite a number of experiments to be conducted. The most common mistake is comparing secondary antibody pricing between various suppliers, when antibody performance is the actual key. Using secondary antibodies in high dilutions also minimizes potential background issues. Agrisera secondary antibodies are high-performing and price-worthy, delivered in an environmentally-friendly way without dry ice, which is costly to produce and transport. You are welcome to check the stock balance of any secondary antibody you need, at any time, here. For the secondary antibodies that are not in stock, the delivery time is around 5-10 business days. During the entirety of 2023, all Agrisera secondary antibodies labelled with ALP and HRP are provided with a 10% discount. Use discount code Conj10 |  Agrisera antibodies perform above market average in terms of dilution. |

| Agrisera IncuBlocker is an "all in one" set for fast Western blot processing. The whole process takes place in a single step, as blocking, as well as primary and secondary antibody binding, occur simultaneously, followed by a wash step with included buffer. Depending on the titer of the primary antibody, it can be re-used up to 5 times (not recommended for quantification work). This means that the processing time can be shortened considerably, to 1.5 hour. Add your primary antibody and use your choice of chemiluminescence or chromogenic method to visualize the reaction. The set is provided for primary antibodies developed in chicken, mouse and rabbit, and is recommended for antibodies to proteins of high and moderate expression. How to know the expression levels of your target protein? Check in the Protein Abundance Database. |  The example above shows how the signal with a primary antibody can be visualized using IncuBlocker. No washes in between, as blocking and primary and secondary antibody incubationsn are done in one step. |
| On the 19th of January, the 14th UCMR Day 2023 took place at Umeå Centre for Microbial Research, Umeå University.

A given laboratory may aim to detect different proteins of varied expression levels, in the tissue being analyzed. Agrisera offers a unique pack of combined reagents, with two different sensitivities. This allows more versatile detection, of high and medium abundancy proteins (Agrisera ECLBright), as well as low abundancy proteins (AgriseraECL SuperBright). Depending on the target protein that we aim to detect, different detection reagent needs to be used, and Agrisera offers this possibility provided in the same set.
In the example above, the aim was to detect a highly abundant photosynthetic protein, PsbA. Using Agrisera anti-PsbA antibodies (AS05 084), a matching secondary antibodies of high titer, goat anti-rabbit, HRP-conjugated (AS09 602) and Agrisera ECL reagent of extreme low femtogram detection range (AgriseraECLSuperBright), resulted in prominently increased background signal. Choosing the other reagent, provided in the Agrisera ECL set, gave the possibility to optimize the result in a very swift manner. There is no need to repeat the whole procedure, as the membrane can be subjected to a wash and developed with less sensitive ECL. It is oftentimes not the primary antibody that contributes to increased background, but rather high load/well, combined with a too sensitive detection reagent.
We are always keen to discuss your results and advice promptly. Contact Agrisera support either using a chat button on the website or by email to [email protected].
| On the 23rd of January, Agrisera conducted the workshop "Western blot – a technique possible to optimize" for researchers and students at the Department of Biological Sciences, Wrocław University, Poland. The workshop was held by Dr. Joanna Porankiewicz Asplund, Agrisera's Technical Support Manager. The meeting gathered 80 participants and was 2 hours long. During the break, the attendees could participate in a quiz, and had a chance to win two ECL reagents with different sensitivities (AS18 SecondaryECL), or a book on photosynthesis. All attendees are very welcome to contact Agrisera with any Western blot and antibody-related questions you may have in the future. Agrisera's Western blot troubleshooting guide, antibody production posters, educational posters and pens were offered to all who attended. Thank you for your particiption and valuable insights! |  |
Secondary antibodies conjugated to HRP (Horseradish peroxidase) and ALP (Alkaline phosphatase) enzymes are most frequently used to visualize target proteins in Western blot, ELISA and immunolocalization. When using secondary antibodies conjugated to HRP, the detection is performed using chemiluminescence (recorded by a CCD camera or another imager), which gives high sensitivity and good resolution in both Western blot and chemiluminescent ELISA. When using antibodies conjugated to ALP, visualization of the antibody binding to the target is achieved using chromogenic reagents, and no CCD camera is necessary. Agrisera's secondary antibody collection is composed of over 220 antibodies; both highly purified and available in a basic format, suitable for Western blot, as well as adsorbed to serum from a wide range of animal species, suitable for immunolocalization and ELISA. Based on the analysis of antibody performance in available publications, conducted by CiteAB, it became very clear that Agrisera secondary antibodies are performing above market average. This means that Agrisera secondary antibodies conjugated to ALP or HRP can be used at high dilutions and are price-worthy reagents, and will provide you with a consistent performance over many experiments.

| Our warmest congratulations to Dr. Sara Raggi who received the Umeå Plant Science Centre (UPSC) Agrisera Prize 2022. Sara was awarded the prize to acknowledge her significant scientific contributions to plant cell and developmental research, as well as her commitment to creating a positive and collaborative work environment at UPSC. The UPSC Agrisera Prize is awarded every year to a person working at UPSC, and this year's prize was announced on the 7th of December during the virtual UPSC Christmas Celebration. Sara Raggi started to work as a postdoc in Prof. Stéphanie Robert’s group at UPSC in 2016 after finishing her PhD. She is involved in many scientific projects and is a co-author of several articles. One of her main projects has been to develop an automated method to measure the angle of unbending Arabidopsis seedlings after germination. This method uses machine learning as basis for the image analysis, and was created together with an engineering master student who Sara supervised. Besides her scientific achievements, Sara Raggi has been actively engaged in improving the work environment at UPSC. She is the postdoc representative, member of the greenhouse introduction team and has helped with outreach events. She has taken over responsibilities in different groups at UPSC, e.g. the gardening group, who set up boxes to grow vegetables in front of UPSC, and the "Greener UPSC" group that aims to promote sustainability at UPSC, and helps organize social events. Every year, anyone working at UPSC can nominate a colleague for the award, and the prize is a travel voucher, sponsored by Agrisera. Based on the written nominations, the members of the UPSC board voted to select the winner. This year, the UPSC Board received 11 nomination letters for seven candidates. Sara was chosen as the winner based nomination letters emphasizing her teamwork skills, scientific excellence and contribution to making UPSC a great place to work. | |

Warm congratulations to PhD students Palwasha Baryalai, Department of Molecular Biology at Umeå University, and Eduardo Rodriguez Soldado, Umeå Plant Science Centre (UPSC), Department of Plant Physiology, Umeå University! They were awarded the Agrisera Best PhD Presentation Award at KBC Days 2022, for their elevator talks and visual abstracts.
Palwasha presented her work "Role of bacterial vesicle associated toxin in potential treatment of cancer", and Eduardo's talk and visual abstract title was "What makes a tree a tree?".
The elevator talks were 2 minutes long, and the visual abstracts had specific criteria to fulfill. The winners were chosen by an evaluation committee, who graded performance very carefully. As Palwasha and Eduardo both performed very well, it was decided to award two winners.
Well done!
| Between the 8th and 9th of November, Agrisera attended the KBC Days, an annual interdisciplinary conference, taking place in person, after having been a digital event for the last two years. KBC is the Chemical Biological Center of Umeå University, and this year the center celebrated its 15-year anniversary. To commemorate this milestone, there was a photo contest with the title "KBC is...", where the participants were invited to share their vision of what KBC is for them. The main theme of the 2022 KBC Days conference was "Big data", and the talks from different areas discussed advantages and challenges of collecting, analyzing and interpreting big data. PhD students held 2 minute elevator picthes, presenting their work, accompanied by visual abstracts. The evaluation committee found it hard to choose only one winner of the Agrisera Best PhD Presentation Prize, and awarded two winners! Thank you to all who came by Agrisera's table to talk antibodies, collect Agrisera Educational Posters, and discuss new antibody ideas. It was great to be able to meet in person again, and we are already looking forward to the 2023 KBC Days! Agrisera will be holding the technical workshop "Western blot – a technique possible to optimize" for KBC, on the 22nd of November, between 13.00 and 15.00, in person as well as online. If you are attending this workshop, you are welcome to send in your Western blot questions in advance! |
