The Abpromise guarantee
Our Abpromise guarantee covers the use of ab270176 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
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.

Flow cytometry staining of C57 BL/6 mouse splenocytes with ab270176 (right) or Rabbit IgG (monoclonal) Alexa Fluor® 488 (ab199091) isotype (left). Cells were incubated for 30 min on ice in 1x PBS containing 10 μg/ml anti CD16/CD32 and 10 % normal goat serum to block FC receptors and non-specific protein-protein interaction followed by the antibody (ab270176) or Rabbit IgG (monoclonal) Alexa Fluor® 488 (ab199091) isotype (1x 106 in 100μl at 5 µg/ml (1/100)) for 30 min on ice. The cells were simultaneously stained with CD3.
Acquisition of >30000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter. Events were gated on live single cells.
