Recombinant Human DLL1/Delta1 Protein,His Tag

Description :
Source Human DLL1/Delta1 Protein is expressed from HEK293 with His tag at the C-terminal. It contains Gln18-Gly540.[Accession |NP_005609] Molecular Weight The protein has a predicted MW of 57.6 kDa. Due to glycosylation, the protein migrates to 60-70 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 50mM Tris, 150mM NaCl (pH 7.5). 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.
