人 alk5蛋白|alk5 protein|alk5(Human, C-human IgG1-Fc & His)（产品说明）
蛋白名称：alk5蛋白, alk5 protein
蛋白构建：A DNA sequence encoding the human TGFBR1 (NP_004603.1) extracellular domain (Met 1-Glu 125) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
表达宿主：HEK293 Cells
蛋白纯度：> 85 % as determined by SDS-PAGE
蛋白活性：1. Measured by its binding ability in a functional ELISA . Immobilized mouse CD105 at 10 μg/ml (100 μl/well) can bind human TGFRB1 with a linear ranger of 6.4-800 ng/ml . 2. Measured by its ability to bind human CD105 in a functional ELISA .
蛋白内毒素：< 1.0 EU per μg of the protein as determined by the LAL method
预测N端：Ala 25
蛋白分子量：The recombinant human TGFBR1/Fc is a disulfide-linked homodimer. The reduced monomer consists of 349 amino acids and has a predicted molecular mass of 38.8 kDa. As a result of glycosylation, the apparent molecular mass of rh TGFBR1/Fc monomer is approximately 45-50 kDa in SDS-PAGE under reducing conditions, with ~10% free Fc fragments.
