Recombinant Mouse ICOS/CD278 Protein,hFc Tag

Description :
Synonyms AILIM; CVID1; CRP-1; MGC39850 Source Mouse ICOS/CD278 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Glu21-Leu144.[Accession | Q9WVS0-1] Molecular Weight The protein has a predicted MW of 40.8 kDa. Due to glycosylation, the protein migrates to 65-80 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 and HPLC. Activity SPR Data: Mouse ICOS, hFc Tag captured on CM5 Chip via Protein A can bind Mouse B7-H2, His Tag with an affinity constant of 0.329 M 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.
