Recombinant Human SEMA4B Protein,His Tag

Description :
Source Human SEMA4B Protein is expressed from HEK293 with His tag at the C-terminal. It contains Leu44-Glu717.[Accession |Q9NPR2] Molecular Weight The protein has a predicted MW of 75.8 kDa. Due to glycosylation, the protein migrates to 80-110 kDa based on Tris-Bis PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by Tris-Bis PAGEand HPLC Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
