Investigate proteins involved in sucrose metabolism with Agrisera antibodies

Sucrose metabolism plays a crucial role in energy production, carbon partitioning, and sugar transport. It is therefore essential for cellular function, growth and development in plants.

Using Agrisera antibodies, proteins involved in various stages of this process can be tracked. 

Sucrose breakdown involves an enzyme called sucrase (invertase), which cleaves sucrose into the monosaccharides glucose and fructose.

Sucrose biosynthesis occurs primarily in the cytoplasm of photosynthetic cells, and involves the enzymes sucrose phosphate synthase (SPS) and sucrose phosphate phosphatase (SPP). These enzymes are involved in the production of sucrose, which can then be transported to other plant tissues for storage or energy utilization.

Shorten the time of Western blot or IL by using directly conjugated primary antibodies

To directly conjugated a primary antibody to an enzyme, like ALP or HRP, or a fluorescent dye, like DyLight®, the antibody must be of the highest purity; purified against the specific antigen. 

Q: What are the benefits of using directly conjugated primary antibodies?

A: The time necessary to complete all steps of a Western blot or immunolocalization protocol, is shortened considerably, as there is no need for secondary antibody incubation and subsequent washes, before the final reaction can be visualized. Potential cross-reactions, which may occur when using secondary antibodies, are also eliminated. Possible sample loss due to washing steps is also reduced. 

Until end of 2024, all directly conjugated Agrisera primary antibodies are discounted by 10%, when applying the discount code Primconj10.

Check out the complete Agrisera collection of directly conjugated primary antibodies here

  Directly conjugated primary antibodies

20 % off for antibodies to proteins involved in electron transfer in photosynthesis

Electron transfer in the thylakoid membrane generates energy through the synthesis of adenosine triphosphate (ATP). The enzyme ATP synthase catalyzes the formation of ATP from adenosine diphosphate (ADP) and inorganic phosphate (Pi), using the proton gradient established across the membrane. Additionally, NADPH, produced during electron transfer, serves as a source of reducing power for the Calvin cycle, where carbon dioxide is fixed and converted into carbohydrates. This process in the thylakoid membrane plays a crucial role in harnessing light energy and converting it into chemical energy.

Agrisera's collection of antibodies to proteins involved in electron transfer offers you the following advantages:
  • Can be used at high dilutions
  • Broad species reactivity, including higher plants, mosses, algae, cyanobacteria and diatoms
  • Suitable for Western blot
  • Cited in hundreds of publications, over the last 20 years

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. 

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

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
