CD4 蛋白|CD4 protein|CD4(Human, His Tag)

人 CD4蛋白|CD4 protein|CD4(Human, C-His)（产品说明）
蛋白名称：CD4蛋白, CD4 protein
蛋白构建：A DNA sequence encoding the human CD4 (NP_000607.1) N-terminal two domains (D1D2) (Met 1-Ser 208) was fused with a polyhistidine tag at the C-terminus.
表达宿主：HEK293 Cells
蛋白纯度：> 94 % as determined by SDS-PAGE
蛋白活性：1. Measured by its ability to bind biotinylated GP140-His(Cat:11677-V08H) in a functional ELISA. 2. Measured by the ability of the immobilized protein to support the adhesion of NIH-3T3 mouse embryonic fibroblast cells. When 5×10^4 cells/well are added to CD4-coated plates (0.8 μg/mL and 100 μl/well), approximately >50 % will adhere specifically after 30 minutes at 37℃.
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 secreted recombinant human CD4 (aa 1-208) consists of 194 amino acids and has a predicted molecular mass of 21.7 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhCD4 is approximately 26 kDa.
蛋白NP号：NP_000607.1
蛋白氨基酸序列：Met1-Ser208
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.
