Anti-PsbA | D1 protein of PSII, C-terminal, DyLight® 650 conjugated (40 µg)

The psbA gene has been cloned from many species of plants, green algae, and cyanobacteria, The psbA gene is located in the chloroplast genome and encodes for the D1 protein, a core component of Photosystem II, PsbA/D1 is rapidly cycled under illumination in all oxygenic photobionts, Tracking PsbA pools using the Global PsbA antibody can show the functional content of Photosystem II in a wide range of samples, Alternative names: 32 kDa thylakoid membrane protein, photosystem II protein D1

Due to biology of PsbA (D1) protein a number of degradation products can apprear in a sample and may be observed when using anti-PsbA antibodies, including products having apparent molecular weights of 24kDa and 16kDa. D1 degradation is a complex set of events and the products observed can be influenced by both the extraction procedure and the physiology of the cells prior to harvest. Third, cross-linking may occur between D1 and cytochrome b559, shifting the protein higher in the gel. In cyanobacteria (PCC7942), three different bands were competed out by preincubating the antibody with the PsbA free peptide, indicating that all bands are indeed PsbA and its precursors or breakdown products. Competition assays were also performed with spinach and Chlamydomonas, confirming the identity of PsbA bands, Anti-PsbA antibodies will not detect D2 protein, as the peptide used to generate PsbA antibodies has no homology to the D2 sequence.DyLight® 650 has Amax = 652 nm, Emax = 672 nm.
