CD19 Mouse Monoclonal Antibody [Clone ID: OTI5F3]

CAT#: CF500363

Carrier-free (BSA/glycerol-free) CD19 mouse monoclonal antibody, clone OTI5F3 (formerly 5F3)

Product Images

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.

• 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.
• Synonyms: B4; CVID3
