Anti-exdpf antibodies enable researchers to detect and measure the exdpf antigen in biological samples. This target is a reported synonym of the PPDPF gene, which encodes pancreatic progenitor cell differentiation and proliferation factor. This protein is known to function in cell differentiation, among other biological roles. The human version of exdpf has a canonical amino acid length of 114 residues and a protein mass of 11.8 kilodaltons, although 2 isoforms have been identified. exdpf is a member of the PPDPF protein family.
