Product and properties Synonyms Complement factor D; C3 convertase activator;Adipsin; PFD Source Rhesus macaque Complement Factor D/CFD Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Gln21-Ala253.[Accession | H9EXC1-1] Molecular Weight The protein has a predicted MW of 25.7 kDa. Due to glycosylation, the protein migrates to 26-30 kDa based on SDS-PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Activity ELISA Data: Immobilized Rhesus macaque Complement Factor D, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-Complement Factor D Antibody, hFc Tag with the EC50 of 16.3ng/ml determined by ELISA. Formulation Lyophilized from 0.22μm filtered solution in 50mM 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 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Storage The product should be stored at -25~-15℃ for 1 year from date of receipt. 2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3 -6 months, -85~-65℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
