Abstract
The invention is directed to enhanced methods for detecting an analyte of interest in situ, by immunoassay, or by hybridization comprising binding an enzyme-labeled conjugate molecule to an analyte of interest in the presence of a redox-inactive reductive species and a soluble metal ion. The enzyme catalyzes the conversion of the inactive reductive species to an active reducing agent, which in turn reduces the metal ion to a metal atom thereby providing an enhanced means of detecting the analyte via metal deposition.
