Purification affinity purified
Background AGI Code: ATCG00020
The PsbA (D1) protein of Photosystem II is rapidly cycled under illumination in all oxygenic photobionts. Disruption of PsbA cycling or losses of PsbA pools are central to photoinhibition of photosynthesis in cyanobacteria, algae and plants under a wide range of conditions including excess light, low temperature and UV exposure. Tracking PsbA pools using the Global PsbA antibody can show the functional content of Photosystem II in a wide range of samples.
Molecular Weight expected: 38 kDa, apparent: 28-30 kDa
UniProt P14660, P0C434, P83755, Q14FH6
Application Notes Recommended Dilution: 1 : 4000 - 1 : 8000 on 5 µg of total protein, detected with standard ECL (WB).
A number of degradation products may be observed when using anti-PsbA antibodies, including products having apparent molecular weights of 24kDa and16kDa. 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 cellsprior 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 willnot detect D2 protein, as the peptide used to generate PsbA antibodies has no homology to the D2 sequence.

The antibody is appropriate for detecting both, 24 kDa or the 10 kDa C-terminal fragments, whichever is generated under given treatment conditions.In our analysis we have seen both, ca. 24 kDa and ca. 10 kDa fragments from different samples, depending on treatments and isolation procedures.This antibody will also detect the phosphorylated form of D1as an alternate band to the main band on a high resolution gel.
