    IHC staining of Purified anti-human HLA-DR, DP, DQ (clone Tü39) on formalin-fixed paraffin-embedded human tonsil tissue. Following antigen retrieval using 1X Tris-Buffered Saline (final concentration 0.05M) with Tween 20 (Cat. No. 925501), the tissue was incubated without (panel A) and with (panel B) 5.0 µg/mL of primary antibody followed by incubation with Alexa Fluor® 647 goat anti-mouse IgG (Cat. No. 405322) for 1 hour at room temperature. Nuclei were counterstained with DAPI (Cat. No. 422801). Images were captured with a 10X objective. Scale bar: 50 µm

HLA-DR, HLA-DP, and HLA-DQ are heterodimeric cell surface glycoproteins comprised of an α (heavy) chain and a β (light) chain. They are 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. Variations in the HLA gene expression are crucial to graft survival.

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 sections, a concentration range of 1 - 10 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Tü39 has been reported to react with a shared epitope of HLA-DR, HLA-DP, and HLA-DQ.

Additional reported applications (of relevant formats) include immunoprecipitation6, in vitro blocking of MLR5, and suppressor cell generation4. The LEAF™ purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (contact our custom solutions team).
