HNK-1 monoclonal antibody binds to human CD57, a 100-115 kDa oligosaccharide antigen expressed by several cell lineages¹. CD57, also known as HNK-1, NK-1, Leu-7 and L2, is present on peripheral blood lymphocyte subsets, including CD8 T cells and NK cells, neural and striated muscle cells^2,3. CD57 antigens are not expressed on erythrocytes, platelets, granulocytes, and monocytes⁴. While the function of CD57 is not well known, studies have shown that it may play a role in neural adhesion and cell-matrix interactions⁵. The antibody was conjugated to a fluorophore and purified by affinity chromatography.
