Description:    Recombinant human CD19 Protein with C-terminal Human Fc and 6xHis tag
Background:     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.
Species/Host:    HEK293
Molecular Weight:    The protein has a predicted molecular mass of 57.1 kDa after removal of the signal peptide.The apparent molecular mass of CD19-hFc-His is approximately 70-100 kDa due to glycosylation.
Molecular Characterization:    CD19(Pro20-Lys291) hFc(Glu99-Ala330) 6×His tag
Purity:    The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining.
Formulation & Reconstitution:    Lyophilized from nanodisc solubilization buffer (20 mM Tris-HCl, 150 mM NaCl, pH 8.0). Normally 5% – 8% trehalose is added as protectants before lyophilization.
Storage & Shipping:    Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature.
