| Formulation |
CD74 protein solution (0.5mg/ml) contains phosphate buffered saline (pH7.4) and 10% glycerol. |
| Purity |
Greater than 85.0% as determined by SDS-PAGE. |
| Description |
CD74 produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 166 amino acids (73-232a.a.) and having a molecular mass of 19.05kDa (Molecular size on SDS-PAGE will appear at approximately 18-28kDa). CD74 is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques. |
| Protein Background |
CD74 (HLA class II histocompatibility antigen gamma chain isoform b), is a transmembrane protein (on antigen presenting cells) which is the invariant chain that chaperones MHC class IIdimers from the endoplasmic reticulum to the cell surface. CD74 is expressed by cells of both T lymphocyte and Blymphocyte lineages. CD74 upregulated in several cancers and is also expressed by non immune cells during inflammation. Diseases related with CD74 include thymic epithelial neoplasm and gastroduodenitis. Among its related super-pathways are Immune System and Immune response Antigen presentation by MHC class II. In addition CD74 functions as cell surface receptor for the cytokine MIF. |
