Abstract

Methods of diagnosis or of quantitation of pathological conditions comprise conducting an immunoassay to measure neo-epitope containing protein fragments naturally present in a biofluid sample, and associating an elevation of the measure in the patient above a normal level with the presence or extent of pathology. The immunoassay is conducted by a method comprising: contacting protein fragments naturally present in the sample with an immunological binding partner reactive with a neo-epitope formed by cleavage of a protein by a proteinase and measuring the extent of binding of peptide fragments to the immunological binding partner to measure therein protein fragments comprising the neo-epitope. Neo-epitopes from, collagen type I, collagen type III, collagen type IV, collagen type V, collagen type VI, elastin, biglycan, decorin, lumican, versican, C-reactive protein, ApoE and laminins are described.
