Disclosed is a homogeneous assay method for determining the presence of a nucleic acid sequence of interest in a sample, comprising combining in solution: the sample; a first nucleic acid probe substantially complementary or homologous to at least part of the sequence of interest and associated, or capable of being associated, with an enzyme or a substance capable of affecting the activity of an enzyme; a second probe capable of binding to the first probe or capable of binding to at least part of the sequence of interest and comprising a ligand moiety; and a binding partner capable of binding to said ligand moiety, the arrangement being such that when the first and second probes are bound in proximity an effect of the binding partner on enzyme behaviour is altered; and monitoring said enzyme behaviour. |
