HEK293T cells were transfected with the pCMV6-ENTRY control (Left lane) or pCMV6-ENTRY CD19 (RC202922, Right lane) cDNA for 48 hrs and lysed. Equivalent amounts of cell lysates (5 ug per lane) were separated by SDS-PAGE and immunoblotted with anti-CD19. Positive lysates LY400678 (100ug) and LC400678 (20ug) can be purchased separately from OriGene.

  Anti-CD19 mouse monoclonal antibody (TA506241) immunofluorescent staining of COS7 cells transiently transfected by pCMV6-ENTRY CD19 (RC202922).

• 

  Living HEK293T cells transfected with either CD19 (RC202922) overexpression plasmid or empty vector control plasmid were immunostained by either anti-CD19 antibody (TA506241) or a nonspecific negative control antibody ([TA180143]) and then analyzed by flow cytometry. CD19 (red) or empty vector (blue) transfected cells with anti-CD19 antibody. CD19 (green) or empty vector (aqua) transfected cells with control antibody (1:100).

• 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.
