Description

HLA-DR is a heterodimeric cell surface glycoprotein comprised of a 36 kD α (heavy) chain and a 27 kD β (light) chain. It is expressed on B cells, activated T cells, monocytes/macrophages, dendritic cells, and other non-professional APCs. In conjunction with the CD3/TCR complex and CD4 molecules, HLA-DR is critical for efficient peptide presentation to CD4+ T cells.

Antibody Type
Monoclonal
Host Species
Mouse
Formulation
test size: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA).
µg size: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation
The antibody was purified by affinity chromatography, and conjugated with FITC under optimal conditions.
Concentration
µg sizes: 0.5 mg/mL
test sizes: lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.)
Storage & Handling
The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application

FC - Quality tested
Recommended Usage

For flow cytometric staining using the µg size, the suggested use of this reagent is ≤2.0 µg per million cells in 100 µl volume. For flow cytometric staining using test sizes, 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.

Excitation Laser
Blue Laser (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 aß 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/µg, Azide-Free, 0.2 µm filtered) (Cat. No. 307648, 307665 - 307669).
