Description

conjugation-Unconjugated-source-Recombinant human CD19 Protein, C-His (Expi293) protein is expressed in HEK293 with C-His. It contains the amino acid sequence of 20-291/556.-gene_id-930-swiss_prot-P15391-applications-ELISA-species-Others-background-CD19 is a transmembrane glycoprotein that is delectively expressed on the cell surface of B-lymphocytes,where it activates intracellular signaling cascades involving both Ras and phosphatidylinositol 3-kinase pathways.Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.-storage_buffer-0.01M TBS(pH7.4)-storage_condition-The product should be stored at -70°C or -20°C.-expression_system-HEK293-tag-C-His-purity->95% as determined by SDS-PAGE-endotoxin-Not Tested
