Lymphocytes proliferate and differentiate in response tovarious concentrations of different antigens. The ability of the Bcell to respond in a specific, yet sensitive manner to the variousantigens is achieved with the use of low-affinity antigenreceptors. This gene encodes a cell surface molecule whichassembles with the antigen receptor of B lymphocytes in order todecrease the threshold for antigen receptor-dependent stimulation.

Titration of the anti-CD19 antibody may be required due to differences in protocols and secondary/substrate sensitivity.

A portion of amino acids 505-532 from the human protein was used as the immunogen for this anti-CD19 antibody.

Aliquot the anti-CD19 antibody and store frozen at -20oC or colder.Avoid repeated freeze-thaw cycles.
