    C57BL/6 mouse frozen spleen section was fixed with 4% paraformaldehyde (PFA) for 10 minutes at room temperature and blocked with 5% FBS for 30 minutes at room temperature. Then the section was stained with 10 µg/ml of CD8a (clone 53-6.7) purified and 10 µg/ml of CD20 (clone SA275A11) Brilliant Violet 421™ (blue) overnight at 4°C, followed by 2.5 µg/ml of anti-rat IgG2a (Clone MRG2a-83) Alexa Fluor® 647 (red) for 2 hours at room temperature. The image was captured by 10X objective.

Recommended Usage

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 µg per million cells in 100 µl volume. For immunohistochemistry on formalin-fixed paraffin-embedded tissue, a concentration range of 2.5 - 5.0 µg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.
