Scientific Data Images for Human Lumican Antibody

Detection of Human Lumican antibody by Western Blot.

Detection of Human Lumican by Western Blot.

Western blot shows lysates of human colon tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Lumican Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2846) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Lumican at approximately 60-85 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Lumican antibody in Human Kidney by Immunohistochemistry (IHC-P).

Lumican in Human Kidney.

Lumican was detected in immersion fixed paraffin-embedded sections of human kidney using Goat Anti-Human Lumican Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2846) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to convoluted tubules.

Detection of Human Lumican by Simple WesternTM.

Simple Western shows lysates of human colon tissue, loaded at 0.5 mg/ml. A specific band was detected for Lumican at approximately 100-180 kDa (as indicated) using 10 µg/mL of Goat Anti-Human Lumican Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2846). This experiment was conducted under reducing conditions and using the 12-230kDa separation system.

Background: Lumican

Lumican is a 40 kDa member of the family of small leucine-rich repeat proteoglycans (SLRPs) and the class II subfamily (1). Human Lumican is synthesized as a 338 amino acid (aa) precursor that contains an 18 aa signal sequence and a 320 aa mature chain. The mature chain contains a negatively charged N-terminal domain containing sulfated tyrosine and disulfide bonds, 12 leucine-rich repeats (LRRs), four potential sites of N-linked glycosylation, and a carboxyl terminal domain containing two conserved cysteines (1). Mature human Lumican is 88%, 87%, and 70% aa identical to mature mouse, rat, and chick Lumican, respectively. SLRPs constitute an important fraction of noncollagenous extracellular matrix proteins (ECM) proteins (1, 2). Lumican is expressed in a variety of tissues, including skin, artery, lung, cornea, kidney, bone, aorta, and articular cartilage (1). Lumican’s role in vivo has been found using Lumican null mice. These mice have functional deficits including corneal opacity as well as skin and tendon fragility associated with disorganized and loosely packed collagen fibers (1, 3‑6). The abnormal connective tissue phenotype seen in the Lumican null mice shows the importance of the role of Lumican in collagen fibrillogenesis (1). In addition to the control of collagen fibril assembly, Lumican has been shown to play a role in the regulation of cell proliferation (7, 8), migration (8, 9), and adhesion (9). Lumican’s overexpression has been reported in carcinoid tumor, breast, colorectal, neuroendocrine, uterine cervical and pancreatic cancers (10).
