Protocol Available protocols: Flow Cytometry (Fixed/Permeabilized), Flow Cytometry (Live) Specificity / Sensitivity CD57 (HNK-1) Mouse Monoclonal Antibody (Pacific Blue™ Conjugate) recognizes the CD57 carbohydrate modification produced by the B3GAT1 protein enzyme. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a membrane antigen from HSB-2 cells. Background CD57 antigen, also known as HNK-1 and Leu7, is a terminally sulfated glycan carbohydrate epitope (glyco-epitope) expressed on a variety of proteins, lipids, and chondroitin sulfate proteoglycans at the cell surface (1,2). CD57 is synthesized by the enzyme B3GAT1 and is present on a subset of peripheral blood lymphocytes, including NK cells and CD8 T cells, as well as neural cells and striated muscle (3-5). Studies have shown that CD57 is not expressed on platelets, monocytes, granulocytes, or red blood cells (6). The CD57 epitope may play a role in neural cell adhesion (7), and characterizes unique maturation states in T and NK cells (8,9). CD57 is an important marker when studying functional immune deficiency in patients with autoimmune diseases, infectious diseases, and cancers (1).
