Nachweis von Antigenen und Antikörpern in einem Testmedium

摘要

There is provided a detection sheet comprising a known antigen or antibody immobilized on a fibrous composite having carried thereon particles of a calcium phosphate compound e.g. tricalcium phosphate, hydroxyapatite or flourapatite, having an average particle diameter of 0.01 to 200 microns and a Ca/P ratio of 1.0 to 2.0. Using this detection sheet, the detection is made by contacting the sheet with a test medium anticipated to show the presence of an antigen or antibody, thereby bonding the anticipated antigen or antibody to said known antigen or antibody of said sheet, and then detecting the resulting antigen-antibody complex upon contact of said complex with a solution of a labeling compound capable of specifically binding to said anticipated antigen or antibody.
