Recombinant Cynomolgus/Rhesus macaque CD19 Protein,His Tag

Description :
Synonyms CD19; B4; CVID3; Leu-12; MGC12802 Source Cynomolgus/Rhesus macaque CD19 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Gln21-Trp291.[Accession | A0A2K5W8L9] Molecular Weight The protein has a predicted MW of 30.96 kDa. Due to glycosylation, the protein migrates to 50-70 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:Anti-CD19 Antibody, hFc Tag captured on CM5 Chip via Protein A can bind Cynomolgus/Rhesus macaque CD19, His Tag with an affinity constant of 0.24 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.
