B2M Detection Service

β2-microglobulin (B2M) is a non-glycosylated protein synthesized by nucleated cells. It is involved in the regulation of cancer cell growth and cancer bone metastasis, and also mediates cancer-related cell signaling networks. B2M is manifested in an increased concentration in body fluids in a variety of cancers and is a biomarker that can be used to indicate the prognosis and treatment effect of these cancers. Creative BioMart Biomarker provides customers with accurate, sensitive and specific cancer biomarker testing services, including B2M detection services. High-quality services, short turnaround time and reasonable prices can effectively help customers shorten the research cycle and reduce research costs.

B2M and Cancers

B2M is a 12kDa small molecular weight protein synthesized by all nucleated cells. B2M is the light chain part of the major histocompatibility complex (MHC) class I antigen that exists on the surface of nucleated cells, and is the key to the efficient transport of the newly born MHC class I heavy chain to the cell surface. MHC class I consist of a long 45kDa heavy chain, a short light chain and a transmembrane domain with a short cytoplasmic domain. it is responsible for presenting endogenous Antigen and activate CD8+ T cells. The binding of B2M to the heavy chain domain is essential to maintain the stability of MHC. MHC class I molecules are expressed on the cell surface. When MHC degrades, the membrane-bound heavy chain is endocytically internalized, and the monomeric B2M is released into the circulatory system. B2M is involved in multiple physiological mechanisms of the body, including immune mechanisms, as well as regulatory mechanisms for cell survival, proliferation, metastasis, and apoptosis. B2M is considered to be a regulator of cancer cell survival and metastasis in solid tumors. It is an active molecule that can stimulate cancer cell growth and angiogenesis, as well as promote epithelial-to-mesenchymal transition (EMT) and bone metastasis. Under normal physiological conditions, the content of B2M in blood and urine is low, while the concentration of B2M is increased in malignant diseases such as solid tumors, lymphomas and multiple myeloma, which indicates the synthesis and release of B2M in these malignant diseases increase. Therefore, B2M has the potential as a cancer biomarker, which may have an indicator effect on the prognosis and treatment effect of cancer patients.
