Anti-PLRP1 antibodies are used in antigen-specific immunodetection in biological samples. The target PLRP1 is a known alias name of the protein pancreatic lipase related protein 1, encoded by the PNLIPRP1 gene in humans. This 467-amino acid residue protein is believed to function as a inhibitor of dietary triglyceride digestion. The protein is secreted and features post-translational modifications.
