C5073-24A	CILP (Cartilage Intermediate Layer Protein 1, CILP-1, Cartilage Intermediate-layer Protein, UNQ602/PRO1188)

Description:
The CILP-1 (cartilage intermediate-layer protein 1) gene product is a 138kD monomeric glycoprotein that is found in both hyaline and fibrocartilage. It is a precursor for two secreted, proteolytically generated products, a 90kD N-terminal CILP-1, and a 62kD C-terminal NTPPHase-homolog. The N-terminus is suggested to serve as both a matrix structural protein, and an IGF-I/TGF-beta1 suppressor sequestration molecule. Human CILP-1 spans aa22-720 of the CILP-1 precursor. It contains one TSP-1 domain (aa149-201) and a C2-type Ig-like region (aa309-395). Over aa1-720 of the CILP-1 precursor, human CILP-1 shares 89% aa identity with mouse CILP-1, and 42% aa identity with human CILP-2.

Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA: 1:128,000
Western Blot: 0.1-0.3ug/ml, observed in rat spinal cord lysates on ~150kD bands
Optimal dilutions to be determined by the researcher.

Storage and Stability:
