重组人 CD4 / LEU3 蛋白 (His标签)（产品说明）
蛋白名称：Human CD4 / LEU3 Protein (His Tag)
蛋白构建：A DNA sequence encoding the human CD4 (NP_000607.1) extracellular domain (Met 1-Trp 390) was fused with a polyhistidine tag at the C-terminus.
表达宿主：HEK293 Cells
蛋白纯度：> 90 % as determined by SDS-PAGE
蛋白活性：Measured by the ability of the immobilized protein to support the adhesion of NIH-3T3 mouse embryonic fibroblast cells. When cells are added to CD4-coated plates (0.8 μg/mL, 100 μL/well), approximately >40% will adhere specifically.
蛋白内毒素：< 1.0 EU per μg of the protein as determined by the LAL method
预测N端：Lys 26
蛋白分子量：The recombinant human CD4 consists of 376 amino acids and has a predicted molecular mass of 42.2 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhCD4 is approximately 46 kDa due to glycosylation.
蛋白NP号：NP_000607.1
蛋白氨基酸序列：Met1-Trp390
蛋白标签：C-His
蛋白保存条件：Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
