Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining using the ?g size, the suggested use of this reagent is ≤1.0 ?g per million cells in 100 ?l volume. For flow cytometric staining using test sizes, the suggested use of this reagent is 5 ?l per million cells in 100 ?l staining volume or 5 ?l per 100 ?l of whole blood.

* Alexa Fluor? 488 has a maximum emission of 519 nm when it is excited at 488 nm.

Application Notes

The L243 monoclonal antibody reacts with the HLA-DR antigen, a member of MHC class II molecules. It does not cross react with HLA-DP and HLA-DQ. Clone L243 binds a conformational epitope on HLA-DRa which depends on the correct folding of the a? heterodimer.19

Additional reported applications (for the relevant formats) include: immunoprecipitation8, Western blotting8, in vitro blocking of mixed lymphocyte reactions9,10, depeletion of MHC class II cells7,?immunohistochemical staining of acetone-fixed frozen sections4,5, and spatial biology (IBEX)21,22. For sensitive functional assays, we recommend using the Ultra-LEAF? purified antibody (Endotoxin < 0.01 EU/?g, Azide-Free, 0.2 ?m filtered) (Cat. No. 307648, 307665 - 307669).

Additional Product Notes

Iterative Bleaching Extended multi-pleXity (IBEX) is a fluorescent imaging technique capable of highly-multiplexed spatial analysis. The method relies on cyclical bleaching of panels of fluorescent antibodies in order to image and analyze many markers over multiple cycles of staining, imaging, and, bleaching. It is a community-developed open-access method developed by the Center for Advanced Tissue Imaging (CAT-I) in the National Institute of Allergy and Infectious Diseases (NIAID, NIH).
