Function
Assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation. -
Involvement in disease
Defects in CD19 are the cause of immunodeficiency common variable type 3 (CVID3) [MIM:613493]; also called antibody deficiency due to CD19 defect. CVID3 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B cells is usually in the normal range, but can be low. -
Sequence similarities
Contains 2 Ig-like C2-type (immunoglobulin-like) domains. -
Post-translational
modificationsPhosphorylated on serine and threonine upon DNA damage, probably by ATM or ATR. Phosphorylated on tyrosine following B-cell activation. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - HRP Anti-CD19 antibody [EPR5906] (ab195896)
IHC image of CD19 staining in a section of formalin-fixed paraffin-embedded normal human tonsil*, performed on a Leica BOND. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab195896, 1/50 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 61 kDa
Observed band size: 85 kDa why is the actual band size different from the predicted?
Exposure time: 3 minutesThis blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab195896 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.
