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 ≤0.25 ?g per million cells in 100 ?l volume.? It is recommended that the reagent be titrated for optimal performance for each application.

Additional reported applications (for the relevant formats) include: immunofluorescence⁴, blocking^6,7,8,9, and immunohistochemistry of acetone-fixed frozen sections^{4, 11}. The LEAF? purified antibody (Endotoxin <0.1 EU/?g, Azide-Free, 0.2 ?m filtered) is recommended for functional assays (Cat. No. 124303). For highly sensitive assays, we recommend Ultra-LEAF? purified antibody (Cat. No. 124318) with a lower endotoxin limit than standard LEAF? purified antibodies (Endotoxin <0.01 EU/?g).
