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

Feedback from participants of previous workshops: 

"Thanks! It was a very nice and informative workshop :)" – Wageningen University & Research Laboratory of Biochemistry, The Netherlands.

"Thank you very much for the workshop! I myself learned quite some additional things, I didn’t know before. And I talked to some of my colleagues just now and they also really liked your workshop. Thanks also for providing the pdf, I will send them to the participants! I really enjoyed your presentation and I can see how dedicated you are about western blots, it was really great to listen to you!" – Max Planck Institute of Molecular Plant Physiology in Potsdam-Golm, Germany.

Detect and quantify Rubisco using antibodies with 20 years of publication record

Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyzes the rate-limiting step of CO2 fixation in photosynthetic organisms. It is demonstrably homologous, from purple bacteria to flowering plants, and consists of two protein subunits, each present in 8 copies. In plants and green algae, the large subunit (~55 kDa) is coded by the chloroplast rbcL gene, and the small subunit (15 kDa) is coded by a family of nuclear rbcS genes.

There are the following advantages of using Agrisera antibodies to Rubisco:
  • Working in very high dilutions, 1: 10 000 1h/RT incubation
  • Broad species reactivity, including higher plants, mosses, algae, cyanobacteria and diatoms. One and the same antibody will detect and quantify Rubisco in thousands of species
  • Suitable for Western blot, immunolocalization and tissue printing
  • Possibility of quantification in quantitative Western blot and ELISA
  • Cited in hundreds of publications, over the last 20 years

In the recent publication by Nuamzanei et al. (2024). "Impact of polyvinyl chloride (PVC) microplastic on growth, photosynthesis and nutrient uptake of Solanum lycopersicum L. (Tomato)", was investigated, using anti-RbcL antibodies from Agrisera.

Which secondary antibody to choose for Western blot for protein detection in plant and algal samples?

A matching secondary antibody, that can be used at high dilutions, will contribute to good Western blot results, with less risk for background signal. Beyond this, it can be used for many experiments, and is therefore very cost-efficient. The differences between secondary antibodies from various suppliers are discussed here.

Agrisera's primary antibodies are produced in chicken, goat, mouse, rabbit and rat. The following high-titer secondary antibodies are appropriate matches: 
At the bottom of each primary antibody product page, you will find a recommended secondary antibody to use with it. 

*This antibody is in the group of the most published antibodies in the world, based on publication record analyses performed by CiteAB.

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.
