The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesCharacterization of leukemias and lymphomas in human lysed whole peripheral blood or mononuclear cells separated by density gradient.
CD19 (FITC) immunofluorescence analysis can be performed on a flow cytometerequipped with an excitation source of 488nm and fitted with logarithmic amplifiers.
10µl ofCD19 (FITC) is sufficient for labelling of 1x106 cells.
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.
