重组人 Siglec-2 / CD22 蛋白 (ECD,His标签)(产品说明)
蛋白名称:Human Siglec-2 / CD22 Protein (ECD,His Tag)
蛋白构建:A DNA sequence encoding the human CD22 isoform-beta (P20273-1) extracellular domain (Met 1-Arg 687) was fused with a polyhistidine tag at the C-terminus.
表达宿主:HEK293 Cells
蛋白纯度:> 95 % as determined by SDS-PAGE
蛋白活性:Measured by its binding ability in a functional ELISA. Immobilized human CD22 (Cat:11958-H08H) at 0.02 μg/ml (100uL/well) can bind anti-human CD22 Mab with a linear range of 0.2-50 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:Asp 20
蛋白分子量:The recombinant human CD22 consists of 679 amino acids and predictes a molecular mass of 76.6 kDa. As a result of glycosylation, it migrates as an approximately 108 kDa band in SDS-PAGE under reducing conditions.
蛋白NP号:P20273-1
蛋白氨基酸序列:Met1-Arg687
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.
