Recombinant Human CD19 Protein, mFc Tag

Molecular Characterization: CD19 (Pro20-Lys291) mFc (Pro99-Lys330) Molecular weight: The protein has a predicted molecular mass of 56.3 kDa after removal of the signal peptide. The apparent molecular mass of CD19-mFc is approximately 70-100 kDa due to glycosylation.Description: Recombinant human CD19 protein with C-terminal mouse Fc tagLymphocytes 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.
