These csp1 ELISA kits are immunodetection tools for measuring the levels of csp1 in biological samples. csp1 is an alias name of the human RCAN1 gene, which encodes the protein, regulator of calcineurin 1. Notably, csp1 is known to play a role in the response to oxidative stress, among other functions. The RCAN1 protein is 252 amino acid residues in length and 28.1 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. This protein is known to be phosphorylated. Other names for this target antigen include ADAPT78 and DSC1.
