Recombinant Mouse CD200/OX-2 Protein,His Tag

Description :
Source Mouse CD200/OX-2 Protein is expressed from HEK293 with His tag at the C-terminal. It contains Gln31-Gly232.[Accession |O54901] Molecular Weight The protein has a predicted MW of 23.6 kDa. Due to glycosylation, the protein migrates to 45-60 kDa based on SDS-PAGE result. 内毒素Endotoxin 1EU per g by the LAL method. Purity > 95% as determined by SDS-PAGEandHPLC Activity SPR Data: Mouse CD200 R1, His Tag immobilized on CM5 Chip can bind Mouse CD200, His Tag with an affinity constant of 1.19 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 tubes before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
