Abstract
A homogenous bioassay including i) a first group containing a short lifetime fluorescent acceptor, and ii) a second group containing a quencher, with the first and second groups linked by at least a first linkage. The bioassay measures the acceptor's fluorescence increase resulting from cleavage of the first linkage and also includes iii) a third group containing a donor for energy transfer to the acceptor, where the donor is an up-conversion fluorescent compound, a long-lifetime fluorescent compound or an electrogenerated luminescent compound. A conformational or terminal epitope is created on the first group through linkage cleavage, and the third group includes a binder with affinity for this epitope. The acceptor's fluorescence is caused by exciting the donor. Also disclosed are bioassay kits for this method.
