Human B7-H3 Antibody

Detection of B7-H3 in Human Lung Cancer via Multiplex Immunofluorescence staining on COMET™​

B7-H3 was detected in immersion fixed paraffin-embedded sections of human lung cancer using Mouse Anti-Human B7-H3 Monoclonal Antibody (Catalog # MAB11611) at 20ug/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). Tissue was stained using the Alexa Fluor™ 647 Goat anti-Mouse IgG Secondary Antibody at 1:200 at 37 ° Celsius for 2 minutes. (Yellow; Lunaphore Catalog # DR647MS) and counterstained with DAPI (blue; Lunaphore Catalog # DR100). Specific staining was localized to the membrane. Protocol available in COMET™ Panel Builder.​​

Detection of Human B7-H3 by Western Blot.

Western Blot shows lysates of U2OS human osteosarcoma cell line. PVDF membrane was probed with 1 µg/ml of Mouse Anti-Human B7-H3 Monoclonal Antibody (Catalog # MAB11611) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for B7-H3 at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Detection of B7-H3 in Human Lung Cancer.

B7-H3 was detected in immersion fixed paraffin-embedded sections of human lung cancer using Mouse Anti-Human B7-H3 Monoclonal Antibody (Catalog # MAB11611) at 5 µg/ml for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to the cell membrane.
