Anti-I309 antibodies enable researchers to detect and measure the I309 antigen in biological samples. This target is a reported synonym of the CCL1 gene, which encodes C-C motif chemokine ligand 1. This protein is known to function in TNF-mediated cellular signaling pathways and chemotaxis, among other biological roles. The human version of I309 has a canonical amino acid length of 96 residues and a protein mass of 11 kilodaltons. It is reported to be a secreted protein. This target antigen may also be known as P500. These I309 antibodies are widely used in Western Blot experiments, among other applications.
