The CILP-1 (cartilage intermediate-layer protein 1) gene product is a 132 kDa (predicted) monomeric glycoprotein that is found in both hyaline and fibrocartilage. It is a precursor for two secreted, proteolytically generated products, a 90 kDa N-terminal CILP-1, and a 62 kDa C-terminal NTPPHase-homolog. The N-terminus is suggested to serve as both a matrix structural protein, and an IGF-I/TGF-beta 1 suppressor sequestration molecule. Human CILP-1 spans aa 22‑720 of the CILP-1 precursor. It contains one TSP-1 domain (aa 149‑201), a C2‑type Ig-like region (aa 309‑395) and six potential N-glycosylation sites. Over aa 1‑720 of the CILP-1 precursor, human CILP-1 shares 89% aa identity with mouse CILP‑1, and 42% aa identity with human CILP-2.

Scientific Data Images for Human CILP‑1 N-Terminal Fragment Antibody
Detection of Human CILP‑1 N-Terminal Fragment by Western Blot.
Western blot shows lysates of human cartilage tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human CILP-1 N-Terminal Fragment Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5504) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for CILP-1 at approximately 100-110 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.Detection of Human CILP‑1 by Simple WesternTM.
Simple Western lane view shows lysates of human cartilage tissue, loaded at 0.2 mg/mL. A specific band was detected for CILP-1 at approximately 133 kDa (as indicated) using 10 µg/mL of Goat Anti-Human CILP-1 N-Terminal Fragment Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5504) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 66-440 kDa separation system.Applications for Human CILP‑1 N-Terminal Fragment Antibody
