CD57, NK CellsCatalogue number: CD57-1
|Product Type||Monoclonal Antibody|
|Application||IHC (cryostat and paraffin sections)|
CD57 (NHK-1) is a glycoprotein with an oligosaccharide antigen determinant, which is localized especially on NK-cells, but also on subsets of T- and B-cells. T-cells expriming CD57 are upregulated in patients with HIV infection and after transplantation. The antigen is also exprimed by neuronal tissues and most neuroendocrine cells. human CD57, a 110 kDa membrane protein of human lymphocytes.
