小鼠 PD-L1蛋白|PD-L1 protein|PD-L1(Mouse, C-His)(产品说明)
蛋白名称:PD-L1蛋白, PD-L1 protein
蛋白构建:A DNA sequence encoding the mouse CD274 (NP_068693.1) extracellular domain (Met 1-Thr 238) was fused with a polyhistidine tag at the C-terminus.
表达宿主:HEK293 Cells
蛋白纯度:> 98 % as determined by SDS-PAGE
蛋白活性:Measured by its binding ability in a functional ELISA. Immobilized recombinant mouse PD-L1 at 1 μg/ml (100 μl/well) can bind mouse PD1 with a linear range of 6.25-400 ng/ml.
蛋白内毒素:< 1.0 EU per μg of the protein as determined by the LAL method
预测N端:Phe 19
蛋白分子量:The secreted recombinant mouse CD274 comprises 231 amino acids and has a predicted molecular mass of 26.3 kDa. As a result of glycosylation, it migrates as an approximately 40-45 kDa band in SDS-PAGE under reducing conditions.
蛋白NP号:NP_068693.1
蛋白氨基酸序列:Met1-Thr238
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.
