Anti-PsbA | D1 protein of PSII, phosphorylated

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.

KLH-conjugated synthetic peptide derived from available plant PsbA sequences with phosphorylated (T), including Arabidopsis thaliana UniProt: P83755, TAIR:AtCg00020, Oryza sativa P0C434 and other higher plant PsbA sequences

Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
