The antibody does not detect Form I RbcL/cbbL,Protein extraction from diatoms protocol can be found here.
Rubisco(ribulose-1, 5-diphosphate carboxylase/oxygenase) catalyzes the rate-limiting step of carbon dioxide fixation in photosynthetic organisms. Form II Rubisco is found in many photosynthetic bacteria and archaea, as well as some photosynthetic dinoflagellates. The large subunit (LSU) of Type I Rubisco is encoded by the RbcL/cbbL gene, and the large subunit of type II Rubisco is encoded by the cbbM gene.
