- Detection of Human Siglec-3/CD33 by Western Blot. Western blot shows lysates of U937 human histiocytic lymphoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Siglec-3/CD33 Monoclonal Antibody (Catalog # MAB11371) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Siglec-3/CD33 at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

- Siglec-3/CD33 in U937 and MOLT-4 Human Cell Lines. Siglec-3/CD33 was detected in immersion fixed U937 human histiocytic lymphoma cell line (left panel; positive stain) and MOLT-4 human acute lymphoblastic leukemia cell line (right panel; negative stain) using Mouse Anti-Human Siglec-3/CD33 Monoclonal Antibody (Catalog # MAB11371) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

- Siglec-3/CD33 in Human Tonsil. Siglec-3/CD33 was detected in immersion fixed paraffin-embedded sections of human tonsil using Mouse Anti-Human Siglec-3/CD33 Monoclonal Antibody (Catalog # MAB11371) 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 Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to lymphocytes.
