Human CD19 is a B cell restricted membrane protein expressed from early stages of B cell development and associates with the antigen receptor complex (1). CD19 is involved in the regulation of B cell proliferation but eventually disappears from plasma cells.
Isotype: Murine IgG1
Immunogen: Human EB-4 Burkitt lymphoma cell line
Specificity: Antibody BU12 recognizes the CD19 molecule of about 95 kd (2).
Functional Application: Antibody BU12 induces adhesion of B cells (3).
