Flow cytometry analysis of CD19 expression by C57BL/6 mouse splenocytes (right panel) compared to an isotype control (left panel). C57BL/6 mouse splenocytes cells were stained with Recombinant CD19 Antibody (AF647) (Ab302111) at 0.1μg/test for 1 hour at 4°C. Left panel - Rat IgG (AF647) (Ab190071).
Flow cytometry analysis of CD19 expression by C57BL/6 mouse splenocytes (red) compared to an isotype control (blue). C57BL/6 mouse splenocytes cells were stained with Recombinant CD19 Antibody (AF647) (Ab302111) at 0.1μg/test for 1 hour at 4°C. Blue - Rat IgG (AF647) (Ab190071). Black - Unlabelled control, cells without incubation with primary antibody.
