Assay mit osmotisch induzierter Abtrennung und Anreicherung hochmolekularer nachzuweisender Substanzen und fluidisches Mikrosystem zu seiner Durchfuehrung

WO 2006092293 A1 UPAB: 20061101 NOVELTY - Assay for carrying out miniaturized affinity tests in a micro-array format comprising concentrating a fraction of the high-molecular substance in measuring chamber, and removing the low-molecular components with the solvent through the membrane pores to attain a high detection sensitivity, where the substance present in the measuring chamber is proved to be a high-molecular substance by optical interactions, radioactivity, electric and magnetic properties, enzymatic markers or catalyzed chemical reactions, is new. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an affinity assay; and (2) a fluid microsystem. USE - Used for carrying out miniaturized affinity tests in a microarray format (claimed). ADVANTAGE - Comfortable separation of high-molecular substance, cost effective, sensitive and short time assay method and high accuracy of affinity tests
