Gene Information

General description

Human leukocyte antigen A classical class I family consists of three members including HLA-A, HLA-B and HLA-C. Members of classical class I major histocompatibility complex (MHC) contain a peptide bound to a transmembrane glycoprotein subunit, the heavy chain, in association with a soluble light chain called β2-microglobulin. Class I MHC are present in changeable volumes on all nucleated cells.
The antibody MEM-81 reacts with human classical MHC Class I molecules in native cell-surface forms. MHC Class I molecules (MHC Class Ia) are expressed on the surface of human nucleated cell types.

The previously assigned protein identifier P01891 has been merged into P04439. Full details can be found on the UniProt database.

Application

The reagent is designed for Flow Cytometry analysis. Suggested working dilution for Flow Cytometry is 1 μg/mL of sample. Indicated dilution is recommended starting point for use of this product. Working concentrations should be determined by the investigator.

Biochem/physiol Actions

Human leukocyte antigen A class I downregulation is implicated in tumor invasion and development. Genetic variations in the class I major histocompatibility complex (MHC) is associated with the development of melanoma. HLA-viral peptide interaction plays a major role in the regulation of human immunodeficiency virus (HIV) infection.
