Specific binding assays utilizing a viable cell as a label

摘要

A method and composition for detecting analyte moieties by means of a signalling moiety capable of aggrandizement are disclosed. The signalling moiety can be attached to or not attached to the analyte moiety/analyte-specific moiety complex. The signalling moiety can be viable or non-viable. The methods disclosed herein provide a sensitive assay for the detection of a wide range of different analyte moieties.
