A method of bioassay for the quantification of peptide fragments comprising a neo-epitope formed by cleavage of mimecan, a protein of an atherosclerotic plaque, by a proteinase is provided. In the method a sample, such as urine or serum, is contacted with an antibody reactive with the neo-epitope and the level of binding of the antibody to peptide fragments in the sample is determined. The assay is predictive of risk of cardiovascular disease events.

Biochemical markers for CVD risk assessment

Provided is a monoclonal antibody specifically reactive with a C-terminal neo-epitope of PIIINP comprised in a C-terminal amino acid sequence CPTGXQNYSP-COOH (SEQ ID NO: 4) in which X is Gly or Pro, and where the monoclonal antibody does not recognize or bind an elongated version of the C-terminal amino acid sequence CPTGXQNYSPQZ-COOH (SEQ ID NO: 5), in which Z is absent or is one or more amino acids of the sequence of collagen type III. Also provided is a method of immunoassay for detecting in a biological sample the C-terminal neo-epitope of PIIINP generated by N-protease cleavage of intact type III procollagen, by contacting the sample with the monoclonal antibody, and determining the amount of binding of the antibody.

PIIINP neo-epitope assay

An immunoassay for the quantification of fragments having an N- or a C-terminal neo-epitope formed by cleavage of a titin protein by a proteinase is provided. The immunoassay includes the steps of contacting a sample with an antibody specifically binding to the N- or C-terminal neo-epitope of the fragments and determining the level of binding.

In vitro assessment of cardiovascular events by assay for neo-eptitopes of titin protein

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.

Pathology biomarker assay

Provided herein are methods of diagnosis or of quantitation of fibrosis. An immunoassay is conducted to measure neo-epitope containing protein fragments of collagen type III, collagen type I, collagen type IV, collagen type V, or collagen type VI, elastin, biglycan, decorin, lumican, versican, perlecan, neurocan, brevican, fibromodulin, serglycin, syndecan, betaglycan, vimentin, or C-reactive protein naturally present in a biofluid sample obtained from a patient. An above normal elevation of the measured protein fragments in the patient is associated with the presence or extent of fibrosis.
