Description
The specific antibody recognizes a 110 kDa protein on Natural killer (NK) cell surface that is identified as CD57. Follicular center cell lymphomas often contain many NK cells within the neoplastic follicles. Cd57 antibody is involved in the biosynthesis of L2/HNK-1 carbohydrate epitope on glycoproteins. It can also play a role in glycosaminoglycan biosynthesis. In HCMV (Human cytomegalovirus) there observed an increased number of
CD57 positive natural killer cells.CD57 expression has been regarded as a marker of terminal differentiation of anergy & senescence.
