摘要:
A bioassay for the quantification of peptide fragments comprising a neo-epitope formed by cleavage of a titin protein by a proteinase comprises contacting a sample with an antibody specifically binding said neo-epitope and determining the level of binding. Partial sequences of titin that may be detected include: 3519' ↓GEYVCDCGTD '13528, 3532' NVTVEARLIK↓ '13542, 3543'↓VEKPLYGVEV '1553.
摘要:
Provided herein is a method of bioassay for the quantification of peptide fragments relevant to neurodegenerative conditions. The method comprises cleaving a Tau protein by a secretase, such as ADAM10, to form a neo-epitope. The method comprises contacting a blood derived sample with an antibody specific for the neo-epitope and determining the level of binding of the antibody to peptide fragments comprising the neo-epitope in the sample. Neo-epitope containing peptide levels are found to be inversely correlated to cognitive function.
摘要:
A method of bioassay for the quantification of peptide fragments comprising a neo-epitope formed by cleavage of a protein of an atherosclerotic plaque by a proteinase, wherein the protein is versican and said method comprises contacting a sample such as urine or serum with an antibody reactive with the neo-epitope and determining the level of binding of said immunological binding partner to peptide fragments in said sample. The assay is predictive of risk of cardiovascular disease events.

Excessive articular cartilage degradation is treated or prevented by administration to a mammal such as a human Pueraria lobata (Kudzu) root or an extract thereof.
摘要:
A method of bioassay for the quantification of peptide fragments comprising a neo-epitope formed by cleavage of a protein of an atherosclerotic plaque by a proteinase, wherein the protein is CRP and said method comprises contacting a sample such as urine or serum with an antibody reactive with the neo-epitope and determining the level of binding of said immunological binding partner to peptide fragments in said sample. The assay is predictive of risk of cardiovascular disease events.
摘要:
A method of bioassay for the quantification of peptide fragments comprising a neo-epitope formed by cleavage of a protein of an atherosclerotic plaque by a proteinase, wherein the protein is decorin and said method comprises contacting a sample such as urine or serum with an antibody reactive with the neo-epitope and determining the level of binding of said immunological binding partner to peptide fragments in said sample. The assay is predictive of risk of cardiovascular disease events.
摘要:
Methods of diagnosis or of quantitation of pathological conditions comprise conducting an immunoassay to measure neo-epitope containing protein fragments naturally present in a bioflui sample, and associating an elevation of said measure in said 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 said 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 said immunological binding partner to measure therein protein fragments comprising said 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.
