The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/3000. Detects a band of approximately 23 kDa (predicted molecular weight: 28 kDa).
PsbP, also known as 23 kDa protein of oxygen evolving complex (OEC),
is a peripheral component of photosystem II located at the lumenal side of the thylakoid membrane. The Arabidopsis genome encodes two PsbP proteins, PsbP1 and PsbP2 and the loss of PsbP in Arabidopsis thaliana results in inability to grow under phototrophic conditions.
In cyanobacteria, PsbP is probably involved in the stabilisation of the charge separation in photosystem II through interaction with the Mn cluster.
