重组人 CD19 / Leu-12 蛋白 (ECD,His标签)（产品说明）
蛋白名称：Human CD19 / Leu-12 Protein (ECD,His Tag)
蛋白构建：A DNA sequence encoding the human CD19 (P15391-1) extracellular domain (Met1-Lys291) was expressed 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：Immobilized Human CD19 His (Cat: 11880-H08H) at 2 μg/ml (100 μl/well) can bind Anti-CD19 Antibody (Cat: 11880-RP01), the EC50 of Anti-CD19 Antibody is 5-40 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：Pro 20
蛋白分子量：The recombinant human CD19 consists of 283 amino acids and predictes a molecular mass of 31.6 kDa. In SDS-PAGE under reducing conditions, rhCD19 migrates as an approximately 47 kDa band due to glycosylation.
