This antibody recognizes human CD19. It has not been tested with other species.
Description
This anti-CD19 antibody is a purified recombinant antibody, which is labeled with R-Phycoerythrin (PE). This antibody has been tested in flow cytometry assay for specific binding to human CD19 on the surface of CD19 CHO Recombinant Cell Line (BPS Bioscience #79561).
assay conditions: One million CD19 CHO recombinant cells (BPS Bioscience #79651>) were blocked and stained with 1 ug of anti-CD19 antibody, PE-labeled (BPS Bioscience #101625) for 30 minutes on ice, washed three times, and analyzed by flow cytometry. CD19 CHO recombinant cells (green) were compared to parental CHO-K1 cells (blue). Y-axis is the cell count. X-axis is PE intensity.
Formulation
8 mM Phosphate, pH 7.4, 110 mM NaCl, 2.2 mM KCl, 0.09% Sodium Azide, 0.2% BSA, and up to 20% glycerol. May contain protein stabilizer.
