Anti-PAP41 antibodies enable researchers to detect and measure the PAP41 antigen in biological samples. This target is a reported synonym of the PRPSAP2 gene, which encodes phosphoribosyl pyrophosphate synthetase associated protein 2. This protein is known to function in bone development, among other biological roles. The human version of PAP41 has a canonical amino acid length of 369 residues and a protein mass of 40.9 kilodaltons, although 4 isoforms have been identified. It is reported to be widely expressed in many tissue types. PAP41 is a member of the Ribose-phosphate pyrophosphokinase protein family. Indicated applications for PAP41 antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
