抗HLA I类抗原单克隆抗体，100TEST，F5662-100TST，Sigma

General description

Monoclonal Anti-Human HLA Class I Antigen (mouse IgG2a isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cell line NS-1 and splenocytes from BALB/c mice immunized with human tonsil leukocyte membrane preparation. Class I proteins are highly polymorphic. HLA-A, -B, -C are classical class I proteins and are heterodimers. HLA-A consists of a polymorphic transmembrane α heavy chain and an invariant water-soluble light chain.
The function of HLA class I molecules is to present antigen to CD8+ lymphocytes. They are involved in the regulation of positive and negative selection of CD8+ T cells by thymic epithelial cells during T cell maturation. These molecules are important in allograft rejection and in the linkage of certain haplotypes in autoimmune diseases. Expression of HLA class I antigens may be modulated in pathological states. Malignant cells may lose these antigens while hepatocytes in alcoholic hepatitis, biliary cirrhosis and chronic active hepatitis may display enhanced reactivity. Increased expression of these antigens is described in muscle cells affected by muscular dystrophy, inflammatory myopathy and other neuro-muscular disorders.

The previously assigned protein identifier P01892 has been merged into P04439. Full details can be found on the UniProt database.
