Study Photosystem I with Agrisera comprehensive antibody set

Over the last 20 years, Agrisera has developed antibodies to study Photosystem I (PSI). This protein complex plays a central role in the conversion of light energy into chemical energy, in the form of ATP and NADPH. This energy is then used to power the biochemical reactions of photosynthesis, and ultimately produce carbohydrates. Agrisera antibodies specifically targeting PSI components can help accurately identify and quantify these proteins in plant, algal and diatom samples. This enables comparative studies, and facilitates the understanding of photosynthetic processes across a wide taxonomic range.

Agrisera PSI antibodies can be applied in:

Western blotting to detect the presence of PSI subunits in plant, algae and diatom samples, which will help in understanding the expression levels of PSI proteins under different experimental conditions.

• Immunofluorescence and Immunohistochemistry to visualize the spatial distribution of PSI within plant and algal cells to study the subcellular localization of PSI and its dynamics under various physiological conditions.

• Co-immunoprecipitation (Co-IP) to identify protein-protein interactions involving PSI subunits or associated proteins. to determine the molecular interactions and protein complexes involved in PSI function and regulation.

Agrisera PSI antibodies will help determine the impact of genetic mutations on PSI function and assembly.

Versatile ECL reagent set, which can save your day!

Question: If something goes wrong with the development of a Western blot with ECL, or if I have too high background or too low signal, can I redo the reaction on the same blot?

Answer: Yes! Within the same day. 
Simply wash the membrane with the appropriate washing buffer, used in your protocol, 1-2 times for 5-10 minutes, and apply another one of the ECL reagents from the Agrisera ECL reagent set. If there is too much background, and a very strong band for the target protein, apply Agrisera ECL Bright. If a target protein band is not detected, apply Agrisera ECL SuperBright

Take advantage of Agrisera antibodies to proteins involved in response to plant pathogen attack

As plants cannot move and change their habitat quickly as animals can, they have instead developed other amazing strategies to cope with various pathogen attacks. Listed below are some examples of plant pathogens.

Fungal diseases: These pathogens typically thrive in warm, moist conditions and can infect various parts of the plant, such as leaves, stems, fruits, and roots.
Bacterial diseases: Bacterial pathogens infect plants through wounds or natural openings, causing diseases like bacterial wilt, leaf spot, and soft rot, and can spread rapidly through the whole plant.
Viral diseases: Viruses can infect plants through vectors such as insects, nematodes, and even human activities, like grafting. Viral diseases can significantly reduce crop yields and quality.
Nematode damage: Nematodes are microscopic roundworms that feed on plant roots, leading to reduced nutrient uptake and stunted growth. Root-knot nematodes, for example, cause the formation of galls on roots, interfering with water and nutrient absorption.

All antibodies to proteins involved in environmental stress response are offered at a 20% discount until the end of March. Use discount code Stress20.

Wide species range of blocking serum for ELISA and immunolocalization

For most immunoassays, like immunolocalization, ELISA or Western blot, blocking is a crucial step. This procedure blocks spaces that are not occupied by immobilized proteins, and thus prevents non-specific binding of the antibodies used in the assay. If blocking is not performed, false signals or high background will occur.

If normal serum is used as a blocker, it is recommended to use serum derived from the same host species as the detection antibody, conjugated with a reporter enzyme, like HRP (Horseradish peroxidase) and ALP (Alkaline phosphatase), or a fluorochrome, like DyLight®, FITC or others. 

Example: 
Primary antibody: Rabbit anti-target protein

Blocking serum: Normal Chicken Serum (usually used at 5% v/v in PBS with Tween®20 detergent)

Secondary antibody: Chicken anti-Rabbit IgG-HRP conjugated

Note: Rabbit serum cannot be used for blocking in such a combination.
 
  Agrisera blocking serum
Agrisera blocking serum from various species, is provided in three purity grades: non-purified, purified on Protein G and ultrapure, available as in research and bulk quantities.

Not certain which blocker to use? Ask Agrisera.

Plant oxidative stress antibody set, 20 % off until end of March

Oxidative stress response in plants involves a complex network of proteins that work together to mitigate the damage caused by reactive oxygen species (ROS), such as superoxide radicals, hydrogen peroxide, and hydroxyl radicals. Below is a list of the main proteins involved in this process:

  • Superoxide dismutase (SOD): Enzyme that catalyzes the dismutation of superoxide radicals into oxygen and hydrogen peroxide. There are different isoforms of SOD found in various cellular compartments, such as cytosol, mitochondria and chloroplast.
  • Catalase (CAT): Enzyme that catalyzes the decomposition of hydrogen peroxide into water and oxygen. It is primarily located in peroxisomes and helps neutralize excess hydrogen peroxide, generated during oxidative stress.
  • Ascorbate peroxidase (APX): Enzyme that uses ascorbate as a reducing agent to scavenge hydrogen peroxide and convert it into water, while oxidizing ascorbate to monodehydroascorbate. This enzyme is crucial for maintaining the redox balance in chloroplasts and other cellular compartments.
  • Glutathione peroxidase (GPX): Enzyme that utilizes glutathione (GSH) as a cofactor to reduce hydrogen peroxide and lipid hydroperoxides to their corresponding alcohols. It plays a significant role in protecting cells from oxidative damage by ROS.
  • Glutathione S-transferases (GSTs): Family of enzymes that catalyze the conjugation of glutathione to a wide range of electrophilic compounds, like lipid peroxides and xenobiotics. They are involved in both detoxification processes and in the regulation of cellular redox status.

   Plant Oxidative Stress antibody set

Choose 5 specific antibodies, combined according to your requirements from the following antibodies:

APX Cat Cu/ZnSOD | FeSOD | HRP Gamma-ECS | GR | GS | MnSOD | RBOHD

Offered at 20% discount until the end of March, with the promotion code Stress20.

20% off antibodies to proteins involved in plant environmental stress response

As environmental conditions are changing, plants have to adapt to cope, as they, unlike animals, are stationary and cannot move to another location. Adaptive mechanisms help plants survive and thrive in challenging conditions and include:
  • Osmotic adjustment
  • Antioxidant defense system
  • Change in root morphology
  • Stomatal regulation
  • Metabolic adjustment
  • Dormancy and shedding
  • Hormonal regulation
  • Symbiotic relationships
  • Epigenetic changes
and the synthesis of stress proteins, which help protect cellular structures and enzymes from damage caused by environmental stress.

These mechanisms collectively allow plants to adapt to their environment, and optimize their chances of survival in the face of various stressors. The specific strategies employed can vary depending on both the type of stress and the plant species involved.

Agrisera's antibody collection to proteins involved in plant stress response
has been developed over many years, in close collaboration with the scientific community.

You can browse our full environmental stress antibody collection, which is discounted by 20% until end of March 2024. Use the discount code Stress20.

The Global Plant Events Calendar is celebrating 5th anniversary

Exactly 5 years ago, in January 2019, Agrisera and Plantae decided to launch The Global Plant Events Calendar to support the plant science community with a good overview of worldwide meetings, conferences and workshops, both in person and online. 

The calendar served as an important resource during the pandemic, when many meetings were cancelled or converted to online events. All events submitted to the calendar are curated, to exclude meetings that do not fit the plant community, as well as so-called "predatory conferences". 

"The calendar is about inclusion, education and quality. We promote smaller, local meetings along with the big, popular ones," says Agrisera's Technical Support Manager, Dr. Joanna Porankiewicz-Asplund, in a recent interview conducted by ASPB. 

She continues; "And you can think about it like this: if you dive into the cell and look at the organelles and research about it, and then if you take that up and translate it into the tree standing in the forest and being exposed to the climate, the calendar will cover almost every event remotely related to that process. So, this is a metaphor for what this calendar is really covering. It’s all the factors of plant science, internal and external. Big and small."

You are welcome to read the full story of the calendar in the interview by Rachel Belsky, ASPB Peer Review & Content Review Coordinator.

On average, there are around 200 meetings listed in the calendar each year. Over the last few years, the calendar has become recognized by organizers of highly recognized meetings, such as GRC (Gordon Research Conferences) and the Global Plant Council.

Discover the advantages of Agrisera detection reagents for ELISA

Agrisera offers detection reagents for ELISA (Enzyme-Linked Immunosorbent Assay), a widely used laboratory technique, employed for detecting and quantifying the presence of specific proteins, antibodies, peptides, hormones, or other substances in a sample. It is a highly sensitive and specific immunological assay, based on the principles of antigen-antibody interactions.

Visualization of antibody binding is usually performed using a secondary antibody, linked to an enzyme like Alkaline Phosphatase (ALP), or Horse Radish Peroxidase (HRP). A substrate specific to the linked enzyme is then added, and visualization is achieved as described below.

Colorimetric detection:
If a chromogenic substrate is used, the enzyme catalyzes a reaction that produces a colored product. The intensity of the color is proportional to the amount of the target substance in the sample. The color change is quantified using a spectrophotometer.

Chemiluminescent detection: If a chemiluminescent substrate is used, the enzyme catalyzes a reaction that produces light. The emitted light is measured using a luminometer. The advantages of chemiluminescent ELISA include its high sensitivity, wide dynamic range, and suitability for quantitative analysis. It is commonly used in various fields, including clinical diagnostics, research laboratories, and pharmaceutical development, where the accurate measurement of protein concentrations is crucial due to its versatility, sensitivity, and ability to handle numerous samples simultaneously.

Until the end of March 2024, Agrisera offers 15% discount on all detection reagents.

Investigation of protein-protein interactions with Agrisera anti-TurboID antibodies

Protein-protein interactions in crop plants can be studied using transient TurboID-based proximity labeling. 

In the recent publication  "Protocol to identify protein-protein interaction networks in Solanum tuberosum using transient TurboID-based proximity labeling" from the Laboratory of Plant Breeding, Wageningen University & Research, The Netherlands, authors Li Shi et al. described the methodology of transient expression of constructs of a protein under investigation, fused to TurboID, and the identification of protein-protein interactions in potato leaves.

The publication describes a detailed protocol for preparation of plant material and transgene desing, as well as protein identification, using Agrisera's anti-TurboID antibody (AS20 4440). The authors also discuss limitations of the protocol, and provide suggestions on how to adress them. 
 
Steps of the protocol include: 
  • Design and Construction of TurboID Fusion Protein with the protein of interest (POI).
    The TurboID enzyme biotinylates nearby proteins within a certain radius (typically tens of nanometers) when activated by the addition of biotin-tyramide and hydrogen peroxide.
  • Expression of POI with TurboID. After expressing the TurboID fusion proteins, cells are treated with biotin-tyramide and hydrogen peroxide to activate TurboID. TurboID then catalyzes the covalent attachment of biotin to nearby proteins within its labeling radius.
  • Protein Extraction: Biotinylated proteins are enriched using streptavidin beads or other methods, isolating the proteins that were in close proximity to the TurboID-fused protein.
  • Protein Identification by Mass Spectrometry. The enriched protein sample is subjected to to mass spectrometry for identification. This helps identify the proteins that were labeled by TurboID.
  • Validation. Identified protein-protein interactions are often validated using additional experimental techniques, such as Western blot.
