Anti-PHS1 antibodies are protein reagents that detect specific antigens. The PHS1 antigen is another term for the human protein prostaglandin-endoperoxide synthase 1, encoded by the PTGS1 gene. The protein is known to function in the regulation of cell proliferation and the response to oxidative stress, among other biological roles. Canonically, it has an amino acid length of 599 residues and a mass of 68.7 kilodaltons. Its subcellular localization is in the ER and membrane and it is widely expressed in many tissue types. The PHS1 protein is a member of the Prostaglandin G/H synthase protein family. Other alias names for PHS1 include COX1, COX3, and PCOX1. Western Blot is the most common application for the PHS1 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
