标题 :Analytical system
发明人：ROTMAN M BORIS
摘要:An analytical system for rapid detection and identification of different analytes directly from a test sample by mixing test material with a germinogenic source and enzyme-free spores, allowing the mixture to stand for a time to allow analyte-induced spore germination and subsequent de novo synthesis of an enzyme capable of producing a germinant in the presence of the germinogenic source and detecting the presence of a germination-derived product. The germinant which is formed promotes further spore germination with concomitant additional de novo enzyme synthesis which results in a propagating cascade of analyte-independent germination after which a germination-derived product can be easily detected. The technique is particularly efficient to conduct thousands of parallel assays in an array of microscopic wells.

摘要:An analytical system for rapid detection and identification of different analytes directly from a test sample by mixing test material with a germinogenic source and enzyme-free spores, allowing the mixture to stand for a time to allow analyte-induced spore germination and subsequent de novo activity of an enzyme capable of producing a germinant in the presence of the germinogenic source and detecting the presence of a germination-derived product. The germinant which is formed promotes further spore germination with concomitant additional de novo enzyme synthesis or activation which results in a propagating cascade of analyte-independent germination after which a germination-derived product can be easily detected. The technique is particularly efficient to conduct thousands of parallel assays in an array of microscopic wells.
