Anti-SISe antibodies are protein reagents that detect specific antigens. The SISe antigen is another term for the human protein C-C motif chemokine ligand 1, encoded by the CCL1 gene. The protein is a reported cytokine that is chemotactic for monocytes but not for neutrophils. Canonically, it has an amino acid length of 96 residues and a mass of 11 kilodaltons. It is a secreted protein. The SISe protein is a member of the Intercrine beta (chemokine CC) protein family. Other alias names for SISe include I-309, I-309, and P500. These SISe antibodies are widely used in Western Blot experiments, among other applications.
