Recombinant Human M-CSF/CSF-1 Protein,His-Avi Tag

Description :
Synonyms MCSF; CSF-1;CSF1; MGC31930 Source Human M-CSF/CSF-1 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Glu33-Asn190.[Accession | P09603-1] Molecular Weight The protein has a predicted MW of 21.3 kDa. Due to glycosylation, the protein migrates to 28-34 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. Activity ELISA Data: Immobilized Human M-CSF, His Tag at 0.5g/ml (100l/well) on the plate. Dose response curve for Human M-CSF R, hFc Tag with the EC50 of 14.2ng/ml determined by ELISA . Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). 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.
