50 µg
蛋白名称：Beta-2 microglobulin蛋白, Beta-2 microglobulin protein
蛋白构建：A DNA sequence encoding the rat B2M (P07151) (Met 1-Met 119) was expressed, fused with a polyhistidine tag at the C-terminus.
表达宿主：HEK293 Cells
蛋白纯度：> 97 % as determined by SDS-PAGE
蛋白活性：0
蛋白内毒素：< 1.0 EU per μg of the protein as determined by the LAL method

文献和实验β2 -微球蛋白（β2 -microglobulin,BMG）分子量为11800，存在于所有有核细胞的表面，特别是淋巴细胞和肿瘤细胞，并由此释放入血循环。它是细胞表面人类淋巴细胞抗原（HLA）的β链（轻链）部分（为一条单链多肽），分子内含一对二硫键，不含糖。半寿期约107分钟，可透过肾小球，但尿仅有滤过量的1%，几乎完全可由肾小管回收。 β2 -微球蛋白在肾功能衰竭、炎症及肿瘤时，血浆中浓度可升高。主要的临床应用在于监测肾小管功能。特别用于肾移植后，如有排斥
