Anti-GRP58 antibodies enable researchers to detect and measure the GRP58 antigen in biological samples. This target is a reported synonym of the PDIA3 gene, which encodes protein disulfide isomerase family A member 3. This protein is known to function in the apoptotic pathway, among other biological roles. The human version of GRP58 has a canonical amino acid length of 505 residues and a protein mass of 56.8 kilodaltons. It is reported to be localized in the ER of cells and widely expressed in many tissue types. Other names for this target antigen include ER60, ERp57, and ERp60. Some GRP58 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
