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 molecules are present in changeable volumes on all nucleated cells.
The antibody W6/32 recognises MHC Class I molecules (MHC Class Ia) that are expressed on the surface of all human nucleated cell types. The antibody W6/32 is a valuable reagent for analysing variations in HLA class I expression in different disease states e.g. liver disease, muscular dystrophy, inflammatory myopathy and other neuromuscular disorders.

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 2-8 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.

Features and Benefits

Evaluate our antibodies with complete peace of mind. If the antibody does not perform in your application, we will issue a full credit or replacement antibody. Learn more.

Physical form

Solution in azide free phosphate buffered saline, pH 7.4; 0.2 um filter sterilized. Endotoxin level is less than 0.01 EU/ug of the protein, as determined by the LAL test.

Spatially controlled, cargo-specific endocytosis is essential for development, tissue homeostasis and cancer invasion. Unlike cargo-specific clathrin-mediated endocytosis, the clathrin- and dynamin-independent endocytic pathway (CLIC-GEEC, CG pathway) is considered a bulk internalization route for the fluid phase, glycosylated membrane proteins and
