Recombinant Biotinylated Human 2B4/CD244/SLAMF4 Protein,His-Avi Tag

Description :
Synonyms CD244; CD244 antigen;2B4; NAIL Source Biotinylated Human 2B4/CD244/SLAMF4 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Cys22-Arg221.[Accession | Q9BZW8-2] Molecular Weight The protein has a predicted MW of 24.9 kDa. Due to glycosylation, the protein migrates to 48-70 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 ELISA Data: Immobilized Biotinylated Human 2B4, His Tag at 0.5g/ml (100l/well) on the streptavidin precoated plate (5g/ml). Dose response curve for Human CD48, hFc Tag with the EC50 of 29.3ng/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.
