Listed are ELISA Kits for the detection of pERp1, an alias name of marginal zone B and B1 cell specific protein. The human protein, encoded by the gene MZB1, is 189 amino acid residues long and has a mass of 20,694 daltons. However, there are up to 5 reported isoforms. It is a member of the MZB1 family. This protein is reported to have a cytoplasmic, nuclear and secreted cellular localization. This target may also be known as: HSPC190, caspase-2 binding protein, mesenteric estrogen-dependent adipose 7, plasma cell-induced ER protein 1, and plasma cell-induced resident ER protein.
