产品英文名称：
Recombinant Human Beta 2 Microglobulin， His Tag

英文简称:
B2M His

中文名称:
重组人β2微球蛋白，His标签

背景资料:
B2M is a part of the MHC class I family that participates in the presentation of peptide antigens to the immune system. B2M is localized on the surface of numerous cells and abundant on the surface of white blood cells. High production or destruction of these cells causes B2M levels in the blood to raise. This increase is observed in people with cancers involving white blood cells， but it is mainly significant in people newly diagnosed with multiple myeloma. B2M Testing is done primarily when evaluating a person for certain kinds of cancer a大肠杆菌中重组表达ecting white blood cells including chronic lymphocytic leukemia， non-Hodgkin’’s lymphoma， and multiple myeloma or kidney disease.

产品描述:
B2M Recombinant Human produced in E.Coli is a single， non-glycosylated polypeptide chain containing 120 amino acids （1-119 a.a.） and having a molecular mass of 14 kDa. The B2M is fused to 21 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.
