ANTI-HUMAN CD19

Mouse

FC - Quality tested

Human Chronic Lymphocytic Leukemia (CLL) cells

（Biolegend-302212）Human peripheral blood lymphocytes were stained with CD19 (clone 4G7) (filled histogram) APC or mouse IgG1, κ isotype control (open histogram) APC.

The antibody was purified by affinity chromatography and conjugated with APC under optimal conditions.

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood.

CD19 is a 95 kD type I transmembrane glycoprotein also known as B4. It is a member of the immunoglobulin superfamily expressed on B-cells (from pro-B to blastoid B cells, absent on plasma cells) and follicular dendritic cells. CD19 is involved in B cell development, activation, and differentiation. CD19 forms a complex with CD21 (CR2) and CD81 (TAPA-1), and functions as a BCR co-receptor.
