重组人 KLK-4 / Kallikrein-4 蛋白 (His标签)(产品说明)
蛋白名称:Human KLK-4 / Kallikrein-4 Protein (His Tag)
蛋白构建:A DNA sequence encoding the human KLK4 (NP_004908.3) (Met 1-Ser 254) was expressed, with a polyhistidine tag at the C-terminus.
表达宿主:HEK293 Cells
蛋白纯度:> 94 % as determined by SDS-PAGE
蛋白活性:Measured by its ability to cleave the fluorogenic peptide substrate Boc-VPR-AMC. (R&D Systems, Catalog # ES011) . The specific activity is >250 pmoles/min/μg. (Activation description: The proenzyme needs to be activated by Thermolysin for an activated form)
蛋白内毒素:< 1.0 EU per μg of the protein as determined by the LAL method
预测N端:Ser 27
蛋白分子量:The secreted recombinant human KLK4 consists of 239 amino acids and predictes a molecular mass of 25.8 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhKLK4 is approximately 30-35 kDa due to glycosylation.
