HIV gp140蛋白|HIV gp140 protein|HIV gp140(HIV, C-human IgG1-Fc)（产品说明）
蛋白名称：HIV gp140蛋白, HIV gp140 protein
蛋白构建：A DNA sequence encoding the HIV-1 envelope glycoprotein gp160 extracellular domain (Ala 29-Ser 661), termed as gp140, was fused with the Fc region of human IgG1 at the C-terminus and a signal peptide at the N-terminus.
表达宿主：HEK293 Cells
蛋白纯度：> 95 % as determined by SDS-PAGE
蛋白活性：Using the Octet RED System, the affinity constant (Kd) of gp140-Fc bound to human CD4 is 0.3 μM.
蛋白内毒素：< 1.0 EU per μg of the protein as determined by the LAL method
预测N端：Ala 29
蛋白分子量：The recombinant HIV-1 gp140 consists of 874 amino acids after removal of the signal peptide and has a predicted molecular mass of 98 kDa. The apparent molecular mass of the recombinant protein is approximately 210-230 kDa in SDS-PAGE under reducing conditions.
蛋白NP号：0
蛋白氨基酸序列：Ala29-Ser661
蛋白标签：C-human IgG1-Fc
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.
