Anti-PDIA8 antibodies enable researchers to detect and measure the PDIA8 antigen in biological samples. This target is a reported synonym of the ERP27 gene, which encodes endoplasmic reticulum protein 27. This protein is known to function in protein folding, among other biological roles. The human version of PDIA8 has a canonical amino acid length of 273 residues and a protein mass of 30.5 kilodaltons. It is reported to be localized in the ER of cells and notably expressed in the pancreas. PDIA8 is a member of the Protein disulfide isomerase protein family.
