HLA-DRA in Human Tonsil via seqIF™ staining on COMET™

HLA-DRA was detected in immersion fixed paraffin-embedded sections of human tonsil using Rabbit Anti-Human HLA-DRA, Monoclonal Antibody (Catalog # MAB11834) at 0.5ug/mL at 37 ° Celsius for 4 minutes. Before incubation with the primary antibody, tissue underwent an all-in-one dewaxing and antigen retrieval preprocessing using PreTreatment Module (PT Module) and Dewax and HIER Buffer H (pH 9; Epredia Catalog # TA-999-DHBH). Tissue was stained using the Alexa Fluor™ Plus 647 Goat anti-Rabbit IgG Secondary Antibody at 1:200 at 37 ° Celsius for 2 minutes. (Yellow; Lunaphore Catalog # DR647RB) and counterstained with DAPI (blue; Lunaphore Catalog # DR100). Specific staining was localized to the membrane. Protocol available in COMET™ Panel Builder.

Immersion fixed paraffin-embedded sections of tonsil

HLA‑DR was detected in immersion fixed paraffin-embedded sections of human tonsil using Rabbit Anti-Human HLA‑DR Monoclonal Antibody (Catalog # MAB11834) at 1 µg/ml overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (VCTS021). Tissue was stained using the HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008) and counterstained with hematoxylin (blue). Specific staining was localized to the membrane.

Detection of Human HLA‑DR by Western Blot.

Western Blot shows lysates of HDLM‑2 human Hodgkin’s lymphoma cell line. PVDF membrane was probed with 0.5 µg/ml of Rabbit Anti-Human HLA‑DR Monoclonal Antibody (Catalog # MAB11834) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008). A specific band was detected for HLA‑DR at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background: HLA-DR

HLA-DR is a transmembrane human major histocompatibility complex 2 (MHC II) family member and consists of a 34 kDa (alpha) subunit and one of several 28 kDa (beta) subunits. HLA-DR is expressed primarily by B cells and dendritic cells (DC), in which it binds peptides derived from internalized and processed antigenic proteins. It presents these peptides on the cell surface for recognition by the T cell receptor on CD4⁺ T cells. This interaction is central to antigen specificity in the adaptive immune response. HLA-DR alleles, polymorphisms, and aberrant expression are linked to a variety of diseases including autoimmunity and cancer.
