摘要:
A method for screening for modulators of the secretion by an osteoclast of a wnt or a wnt signal enhancer comprises exposing osteoclasts in culture to a compound to be screened, exposing a wnt sensitive detection system to conditioned medium from said osteoclast culture, and determining whether a wnt signal is present in said medium by assaying for wnt mediated activation of bone formation by osteoblasts or by wnt mediated activation of LRP5 and or LPR6 signalling in a cell by detection of β catenin or detection of translocation of dishevelled, axin, or Fratl to the cell membrane of said cell.
摘要:
Provided is a method of bioassay for the quantification of peptide fragments elevated in lung diseases such as COPD, SCC, or IPF. The peptide fragments comprise a neo-epitope formed at a cleavage site by cleavage in vivo of elastin by a proteinase. In the method a sample is contacted with an antibody having specific binding affinity for the neo-epitope amino acid sequence and determining the level of binding is determined where the antibody binds one of the following terminal sequences: . . . FGPGVV, . . . VPGLGV or IKAPKL . . . . Also provided are antibodies and immunoassay kits for use in such methods.
摘要:
An assay for citrullinated fragments of SOCS-2, Alpha 1 anti tyrpsin, versican, biglycan, laminin, or other protein having a terminal antibody binding site comprising citrulline in a blood derived sample shows diagnostic relevance in relation to rheumatoid arthritis or fibrotic disease.
摘要:
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.
