mouse monoclonal IgG1; CaBP1 Antibody (A-4) is an IgG1 λ mouse monoclonal CaBP1 antibody (also designated CaBP1 antibody) that detects the CaBP1 protein of mouse, rat and human origin by WB, IP, IF and ELISA. CaBP1 Antibody (A-4) is available as both the non-conjugated anti-CaBP1 antibody form, as well as multiple conjugated forms of anti-CaBP1 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. The calcium binding protein (CaBP) family shares much similarity to calmodulin. It has been shown that CaBP proteins can substitute functionally for, and probably augment the function of, calmodulin. Calcium binding proteins are a crucial part of calcium mediated cellular signal transduction in the central nervous system. There are several members of the family with varying expression patterns. CaBP1 and CaBP2 can be expressed as multiple, alternatively spliced variants in brain and retina. CaBP3, CaBP4 and CaBP5 are restricted to retinal rod and cone cells.
