Recombinant Human B2M/beta 2-Microglobulin (His Tag)

Description :
FAQ COA 已发表文献 Beta 2-Microglobulin (B2M) forms the light chain of Class I MHC molecules. It has been measured in a variety of body fluids, including serum/plasma, saliva, CSF, and urine. B2M freely passes through the glomerular membrane, but it is nearly completely reabsorbed and degraded in proximal tubule cells. Clinically, serum B2M is elevated in rheumatoid arthritis, systemic lupus erythematosus, viral infections, and conditions associated with decreased glomerular filtration. 产品性质 别名 Beta-2-microglobulin;B2M;-2-microglobulin Uniprot No. P61769.1 Recombinant Human B2M/beta 2-MicroglobulinProtein is expressed from HEK293Cellswith His tag at the C-terminal. It contains Ile21-Met119. 分子量 Approximately 12.8 kDa. Due to glycosylation, the protein migrates to 13-15 kDa based on Tris-Bis PAGE result. > 95% as determined by SDS-PAGEand HPLC. 内毒素 1.0EU per 1g of the protein by the LAL method. Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. 复溶 Centrifuge tubes before opening. Reconstituting to a concentration more than 100 g/mL is recommended (usually we use 1mg/mLsolution for lyophilization). Dissolve the lyophilized protein in distilled water.
