MHC Class I (clone HI21), anti-human

Protein Family: Cellular Antigens

Pathway and Disease: Immune System

Description:
MHC Class I (HI21) antibody recognizes class I major histocompatibility complex (or human leukocyte antigen) monomorphic antigen which is expressed widely on human nucleated cells such as lymphocytes, monocytes/ macrophages, dendritic cells and other hematopoietic and non-hematopoietic nucleated cells, and platelets. The expression of HLA-I antigen varies with cell types and decreases with cell maturation, e.g. low expression on mature granulocytes and almost null on mature erythrocytes. HLA-I antigen is also expressed on most cells of human leukemic cell lines, but not or low in Daudi and K562 cell lines and nerve cells. In addition to membrane HLA-I antigen, a soluble form of HLA-I can be detected in serum.

Alternate Names: HLA-I, HLA class I histocompatibility antigen, MHC class I antigen

Application Notes: Purified antibody is suitable for immunohistochemistry with acetone-fixed frozen and formalin-fixed paraffin sections. E: 1:500-1:1,000; FC: 1:200-1:1,000; IHC: 1:200-1:500

Format: Each vial contains 0.1 mg IgG in 0.1 ml (1 mg/ml) of PBS pH7.4 with 0.09% sodium azide. Antibody was purified by Protein-G affinity chromatography.
