Capillary zone electrophoresis of collagen type I CNBr peptides in acid buffers.
Collagen type-I CNBr peptides were separated under acidic conditions by capillary electrophoresis. Separation conditions were: 100 mM phosphate buffer pH 2.5, 50 cm x 50 microns capillary (placed in a cartridge), 8 kV, running time 30-45 min, detection by UV at 200 nm. The peptides were separated strictly by their molecular mass and the overall pattern was well comparable to RP-HPLC separations...
متن کاملMapping the heparin-binding sites on type I collagen monomers and fibrils
The glycosaminoglycan chains of cell surface heparan sulfate proteoglycans are believed to regulate cell adhesion, proliferation, and extracellular matrix assembly, through their interactions with heparin-binding proteins (for review see Ruoslahti, E. 1988. Annu. Rev. Cell Biol. 4:229-255; and Bernfield, M., R. Kokenyesi, M. Kato, M. T. Hinkes, J. Spring, R. L. Gallo, and E. J. Lose. 1992. Annu...
متن کاملExpression of genes encoding the collagen-binding heat shock protein (Hsp47) and type II collagen in developing zebrafish embryos
Hsp47 is a heat-shock protein which interacts with newly synthesize procollagen chains in the endoplasmic reticulum (ER) of collagen-secreting cells and is thought to assist in procollagen triple helix assembly and subsequent transport to the cis-Golgi. This is supported by studies which have reported that genes encoding collagen and Hsp47 are subject to co-ordinate increases and decreases in e...
متن کاملAre there autoantibodies reacting against citrullinated peptides derived from type I and type II collagens in patients with rheumatoid arthritis?
OBJECTIVES To assess the possible presence in patients with rheumatoid arthritis (RA) of autoantibodies recognising citrullinated peptides derived from type I and II collagens. METHODS Firstly, the binding of four pairs of synthetic peptides (arginine-containing and artificially citrullinated forms) related to different regions of human type II collagen were tested with sera from 120 patients...
متن کاملA synthetic peptide derived from the sequence of a type I collagen receptor inhibits type I collagen-mediated platelet aggregation.
A synthetic peptide-1, an 18 amino acid residue peptide derived from a hydrophilic domain of a cloned platelet type I collagen receptor, was used to study the role of the receptor on types I and III collagen-induced platelet aggregation and the release of ATP. The peptide inhibits the type I, but not the type III, collagen-induced platelet aggregation and the release of ATP in a dose-dependent ...
