Anti-CPF antibodies enable researchers to detect and measure the CPF antigen in biological samples. This target is a reported synonym of the NR5A2 gene, which encodes nuclear receptor subfamily 5 group A member 2. This protein is known to function in acinar cell differentiation and cholesterol metabolism and homeostasis, among other biological roles. The human version of CPF has a canonical amino acid length of 541 residues and a protein mass of 61.3 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include B1F and B1F2. Western Blot is the most common application for the CPF antibodies listed below. ELISA and Immunohistochemistry are also common applications.
