Recombinant Mouse IFN alpha 1 Protein,hFc Tag

Description :
Synonyms Interferon alpha-1/13;LeIF D;Interferon alpha-D; IFN alpha1 Source Mouse IFN alpha 1 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Cys24-Lys189.[Accession | P01572] Molecular Weight The protein has a predicted MW of 45.88 kDa. Due to glycosylation, the protein migrates to 50-60 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 SDS-PAGE Activity SPR Data: Human IFN alpha/beta R1, His Tag captured on CM5 Chip via anti-his antibody can bind Mouse IFN alpha 1, hFc Tag with an affinity constant of 11.96 nM as determined in SPR assay . 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.
