Reference Data

Target NameHomo sapiens CD19 molecule (CD19), transcript variant 2
Alternative NameB4; CVID3
Database LinkNP_001761
FunctionLymphocytes 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.

Immunohistochemical staining of paraffin-embedded Human lymph node tissue using anti-CD19 mouse monoclonal antibody. (UM500071; heat-induced epitope retrieval by 10mM citric buffer, pH6.0, 120C for 3min)
Immunohistochemical staining of paraffin-embedded human tonsil using anti-CD19 clone UMAB103 mouse monoclonal antibody at 1:200 dilution of 0.6mg/mL and detection with Polink2 Broad HRP DAB. UM500071 requires heat-induced epitope retrieval with citrate pH6.0 at 95-100C 20 minutes. . The image shows strong membranous and cytoplasmic staining in >40 % of non germinal center cells of tonsil and >90% of the germinal center cells. No staining was seen in the squamous epithelia cells.
