Recombinant Human ULBP-4 Protein,hFc Tag

Description :
Synonyms N2DL-4; NKG2DL4; RAE-1-like transcript 4; RAET1E; LETAL; N2DL4; ULBP4; Source Human ULBP-4 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains His31-Asp225.[Accession | Q8TD07-1] Molecular Weight The protein has a predicted MW of 49.12 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:Human ULBP-4, hFc Tag captured on CM5 Chip via Protein A can bind Human NKG2D, His Tag with an affinity constant of 0.17 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.
