Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase.

Our Abpromise guarantee covers the use of ab1168 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|Flow Cyt||Use at an assay dependent concentration.
Characterization of leukemias and lymphomas in human lysed whole peripheral blood or mononuclear cells separated by density gradient. CD19 (PE) immunofluorescence analysis can be performed on a flow cytometerequipped with an excitation source of 488nm and fitted with logarithmic amplifiers. 10µl of CD19 (PE) is sufficient for labelling of 1x106 cells.
ab91357 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
FunctionAssembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.
Involvement in diseaseDefects 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 similaritiesContains 2 Ig-like C2-type (immunoglobulin-like) domains.
modificationsPhosphorylated on serine and threonine upon DNA damage, probably by ATM or ATR. Phosphorylated on tyrosine following B-cell activation.

ab1168 used in Flow Cytometry.
Whole PBMC cells from Rhesus monkey were fixed with paraformaldehyde. The lymphocyte population was gated based on forward and side scatter properties. The cells within the gate were then analysis on 2 color dot plots with the CD19 (clone CB19) plotted on one axis and other lineage makers plotted on the other axis. CD3 and NKG2a positive population were negative for CD19 staining.All CD20 positive cells also stained positive for CD19. Addition analysis was carried out to verify that the monocyte and granulocyte populations were negative for staining with this CD19 antibody as is expected.
