Detection of Mouse Intelectin‑1/Omentin by Western Blot. Western blot shows lysates of mouse small intestine tissue. PVDF membrane was probed with 2 µg/mL of Rat Anti-Mouse Intelectin‑1/Omentin Monoclonal Antibody (Catalog # MAB8074) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for Intelectin‑1/Omentin at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Intelectin‑1/Omentin in Mouse Intestine. Intelectin‑1/Omentin was detected in perfusion fixed frozen sections of mouse intestine using Rat Anti-Mouse Intelectin‑1/Omentin Monoclonal Antibody (Catalog # MAB8074) at 25 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to Paneth cells in intestinal glands. View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Intelectin (endothelial lectin; also ITLN-1 and omentin) is a 34 kDa Ca-dependent galactofuranose-binding lectin that is not a C-type lectin. It is expressed in intestinal and airway epithelium and appears to participate in insulin signaling and microbe recognition. Intelectin-1 is upregulated in asthma and contributes to allergic airway inflammation. The mouse Intelectin-1 preproprecursor is 313 amino acids (aa) in length. It contains a 19 aa signal sequence, a 279 aa mature segment (aa 20-298), and a 15 aa C-terminal proregion that is cleaved to generate a GPI-linkage. Soluble Intelectin-1 can be released from omental adipose tissue and malignant pleural mesothelioma. One fibrinogen-related domain exists in the mature molecule (aa 32-251). Human Intelectin-1 exists as a disulfide-linked glycosylated homotrimer; mouse is unglycosylated and a monomer. Mature mouse Intelectin-1 is 82% aa identical to human Intelectin-1.
