|---|---|
| 纯化说明 | 0.22 µm filter sterilized. Endotoxin level is less than 0.1 EU/µg of the protein, as determined by the LAL test. |
| 纯度 | > 97% (by SDS-PAGE) |
| 缓冲液 | PBS (pH 7.4) |
| 复溶 | Reconstitute to a concentration of 0.1 - 0.5 mg/ml in sterile distilled water. |
| 存放说明 | For long term, lyophilized protein should be stored at -20°C or -80°C. After reconstitution, aliquot and store at -20°C for up to one month, at 2-8°C for up to one week. Storage in frost free freezers is not recommended. Avoid repeated freeze/thaw cycles. Suggest spin the vial prior to opening. |

| 基因名称 | B2M |
| 全名 | beta-2-microglobulin |
| 背景介绍 | This gene encodes a serum protein found in association with the major histocompatibility complex (MHC) class I heavy chain on the surface of nearly all nucleated cells. The protein has a predominantly beta-pleated sheet structure that can form amyloid fibrils in some pathological conditions. The encoded antimicrobial protein displays antibacterial activity in amniotic fluid. A mutation in this gene has been shown to result in hypercatabolic hypoproteinemia. [provided by RefSeq, Aug 2014] |
| 生物功能 | Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. Exogenously applied M.tuberculosis EsxA or EsxA-EsxB (or EsxA expressed in host) binds B2M and decreases its export to the cell surface (total protein levels do not change), probably leading to defects in class I antigen presentation (PubMed:25356553). [UniProt] |
| 细胞定位 | Secreted. Cell surface. Note=Detected in serum and urine (PubMed:1336137, PubMed:7554280). Note=(Microbial infection) In the presence of M.tuberculosis EsxA-EsxB complex decreased amounts of B2M are found on the cell surface (PubMed:25356553). [UniProt] |
| 预测分子量 | 14 kDa |
| 翻译后修饰 | Glycation of Ile-21 is observed in long-term hemodialysis patients. [UniProt] |
