Recombinant Cynomolgus B7-H7/HHLA2 Protein,His Tag

Description :
Synonyms B7H7; B7-H7; HHLA2; B7 Homolog 7 Source Cynomolgus B7-H7/HHLA2 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ile21-Asn345.[Accession | XP_005548285.2] Molecular Weight The protein has a predicted MW of 38.31 kDa. Due to glycosylation, the protein migrates to 60-70 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 SPR Data:Cynomolgus B7-H7, His Tag captured on CM5 Chip via anti-his antibody can bind Human CD28H, hFc Tag with an affinity constant of 7.86 nM as determined in SPR assay . Formulation Lyophilized from 0.22 m 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.
