Summary for Patent: 5,320,970
Title: Detection of collagen degradation in vivo
Abstract:Methods of determining collagen degradation in vivo, by quantitating the concentration of a peptide in a body fluid, the peptide having the following structure: ##STR1## is hydroxylysyl pyridinoline or lysyl pyridinoline, and J is pyroglutamic acid or glutamine and (Leu) are optional leucines, are disclosed. Compositions useful in quantitating collagen peptides to determine the rate of bone resorption are prepared by treating bone with a protease, such as collagenase, and purifying the compositions so as to enrich them with peptides capable of binding to the monoclonal antibody MAb-1H11.
