Recombinant Human CD19 Protein, Myc/DDK-tagged, C13 and N15-labeled

• Cat.No.: CD19-809H
• Product Overview: CD19 MS Standard C13 and N15-labeled recombinant protein (NP_001761) with a C-terminal MYC/DDK tag, was expressed in HEK293 cells.

Specification

• Description: 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.
