Recombinant Human Complement factor I Protein,His Tag

Description :
Synonyms C3B/C4B inactivator;EC:3.4.21.45; CFI Source Human Complement factor I Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Lys19-Val583.[Accession | P05156] Molecular Weight The protein has a predicted MW of 64.58 kDa. Due to enzyme lysis and glycosylation, the protein migrates to 75-95 kDa based on SDS-PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Formulation Lyophilized from 0.22m filtered solution in 20mM Tris, 150mM NaCl (pH 8.0). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
