Data Examples

Western Blot Detection of Human COX‑2 by Western Blot. View Larger

Detection of Human COX‑2 by Western Blot. Western blot shows lysates of human peripheral blood mononuclear cells (PBMC) untreated (-) or treated (+) with LPS. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human COX-2 Monoclonal Antibody (Catalog # MAB4198), followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for COX-2 at approximately 75 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Immunocytochemistry COX‑2 in A549 Human Cell Line. View Larger

COX‑2 in A549 Human Cell Line. COX-2 was detected in immersion fixed A549 human lung carcinoma cell line using Mouse Anti-Human COX-2 Monoclonal Antibody (Catalog # MAB4198) 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 cytoplasm.

Immunohistochemistry COX‑2 in Human Breast Cancer Tissue. View Larger

COX‑2 in Human Breast Cancer Tissue. COX-2 was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using Mouse Anti-Human COX-2 Monoclonal Antibody (Catalog # MAB4198) at 1.7 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm.

Background: COX-2

Cyclooxygenase-2 (COX-2) also known as prostaglandin G/H synthase 2 (PGHS2) is a 70 kDa microsomal enzyme that belongs to the prostaglandin G/H synthase family. It is inducibly-expressed by a number of cell types, including fibroblasts, vascular smooth muscle cells, endothelium, and monocytes. Functionally, COX-2 is a homodimer that catalyzes two steps in the conversion of arachadonic acid to prostaglandin H2. Mature human COX-2 is 587 amino acids (aa) in length and contains one EGF-like domain (aa 18‑55), a potential membrane interacting region (aa 277‑292) and a globular catalytic domain (aa 293‑604). At least one splice form exists that shows an 11 aa substitution for the C-terminal 451 amino acids. Over the amino acid range of the immunogen, human COX-2 shows 83% aa identity to mouse COX-2.
