Agrisera reagents for successful protein detection in Western blot

Agrisera supports protein detection in your laboratory with tailored reagents with the following features:

High sensitivity
Long-term stability
Suitable for PVDF and nitrocellulose membranes
Superior lot-to-lot consistency
Competitive pricing

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.

Agrisera supported the 20th Scientific Conference of the Phycological Section of the German Botanical Society

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.

Advantages of Agrisera secondary antibodies labelled with ALP and HRP

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.

IncuBlocker - efficient way to shorten Western blot time

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.

Highly performing matching secondary antibody for Agrisera rabbit primary antibodies

Agrisera goat anti-rabbit IgG secondary antibodies, conjugated to horseradish peroxidase (HRP), perform in dilution > 1: 25 000 in Western blot and ELISA, which is supported by a long list of publications.

As this anti-rabbit IgG secondary antibody performs in high dilutions, it offers advantages to other secondary antibodies in terms of minimizing background signal, and the number of experiments it can be used for. This makes it very economical, and strengthens experimental reproducibility.

Additionally, this antibody is provided in lyophilized format, which makes shipment economical and environmentally friendly, as there is no need to include dry ice. Shipments are done at ambient temperature, with perserved antibody performance, which has been tested and evaluated over the last 20 years.

Until the end of 2023, this product is offered at a 10% discount using the discount code: Conj10.

Agrisera high titer goat anti-rabbit IgG secondary antibodies conjugated to HRP

To the product: 1 mg or trial size.

One set, two ECL reagents with different sensitivities, helps with versatile detection

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].

Agrisera Western blot workshop at Wrocław University

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.

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!

Take an advantage of high performing price-worthy Agrisera secondary antibodies

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.

We are always eager to provide prompt advice on which Agrisera secondary antibody is best suited for the experiments you aim to perform.
