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.

Product Details

Reactivity
Human, African Green, Baboon, Chimpanzee, Cynomolgus, Dog (Canine), Marmoset, Rhesus, Squirrel Monkey, Tamarin
Antibody Type
Monoclonal
Host Species
Mouse
Formulation
Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and 0.2% (w/v) BSA (origin USA).
Preparation
The antibody was purified by affinity chromatography, and conjugated with APC under optimal conditions.
Concentration
Lot-specific (please contact technical support for concentration and total µg amount, or use our Lookup tool if you have a lot number.)
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

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.

Excitation Laser
Red Laser (633 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, and immunohistochemical staining of acetone-fixed frozen sections4,5. 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).
