Monoclonal antibodies for detection of urinary trypsin inhibitors
View Patent ↗Certain monoclonal antibodies are able to detect urinary trypsin inhibitors (UTIs) that are characteristic of disease in humans. In particular, the UTIs include AMBK, Bikunin, Uristatin, Uristatin-1, Uristatin-2, as defined herein, also including the fragments and aggregates thereof.
1. A method of assaying a biological fluid for urinary tryspin inhibitors (UTI) selected from the group consisting of uristatin, uristatin-1, uristatin-2 and THP comprising contacting a sample of biological fluid with a monoclonal antibody against purified uristatin and detecting said UTIs bound by said monoclonal antibody.
2. A method of claim 1 , wherein said monoclonal antibody is secreted by a hybridoma selected from the group consisting of ATCC 421-5G8.1A8.5C1, ATCC 420-5D11.5G8.1E4, and ATCC 421-3G5.4C5.3B6.
3. A method of claim 2 , wherein said monoclonal antibody is secreted from hybridoma ATCC 421-5G8.1A8.5C1.
4. A method of claim 2 , wherein said monoclonal antibody is secreted from hybridoma ATCC 420-5D11.1E4.
5. A method of claim 2 wherein said monoclonal antibody is secreted from hybridoma ATCC 421-3G5.4C5.3B6.
6. A method of claim 2 wherein said UTIs are detected in an immunoassay.
7. A method of claim 6 wherein said immuno assay is selected from the group consisting of MIC (microparticle capture immunoassays, LAI (latex agglutination inhibition), IC (solid phase chromatographic), RIA (radio immunoassays), ELISA (enzyme linked immunoabsorbent assay), BIA (enzyme linked assays), FIA (fluorescence linked assays), LIA (luminescence linked assays), CLA (chemiluminescence assays), OA (optical color label assays), EST (electrochemical signal transducers) and rare earth metals label assays.
8. A method of claim 1 wherein said biological fluid is urine.
9. A method of claim 1 wherein said biological fluid is blood plasma.
