β2-microglobulin (B2M) is a non-glycosylated polypeptide composed of 99 amino acids. It is present on the surface of all nucleated cells. The protein is characterized with the single polypeptide chain, which is linked noncovalently to major histocompatibility complex (MHC) class I cell surface antigen. The gene coding for B2M is mapped to human chromosome 15q.
Immunogen
Purified isolated human beta2-microglobulin
Application
The reagent is designed for Flow Cytometry analysis. Suggested working dilution 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
β2-microglobulin (B2M) plays a vital role in cell survival, proliferation and metastasis in various types of cancer. Elevated concentration of β-2-microglobulin (B2M) can be considered as a prognostic marker for hemophagocytic lymphohistiocytosis (HLH). Elevated concentration of circulating B2M, due to renal dysfunction and long term hemodialysis leads to dialysis-related amyloidosis. Overexpression of serum B2M is observed in hepatitis C virus (HCV) related chronic liver diseases, therefore it might act as a potential marker for the HCV disease progression towards cirrhosis and carcinoma. Missense mutation in the B2M gene results in familial hypercatabolic hypoproteinemia (FHH).

Linkage relationships of homologous loci in man and mouse were used to estimate the mean length of autosomal segments conserved during evolution. Comparison of the locations of greater than 83 homologous loci revealed 13 conserved segments. Map distances between the

β2-Microglobulin (β2m), a key component of the major histocompatibility class I complex, can aggregate into fibrils with severe clinical consequences. As such, investigating the structural aspects of the formation of oligomeric intermediates of β2m and their subsequent progression toward fibrillar

Egypt has the highest prevalence of HCV infection in the world (~14.7%). Around 10-15% of HCV-infected persons will advance to cirrhosis within the first 20 years. The incidence of HCC is expected to grow in the next two decades, largely
The nonclassical MHC class-I molecule, FcRn, salvages both IgG and albumin from degradation. Here we introduce a mechanism-based kinetic model for human to quantify FcRn-mediated recycling of both ligands based on saturable kinetics and data from the literature using easily
