The present invention concerns a system and method for the luminescence detection of an analyte in a liquid sample. The system comprises a support on which an analyte-specific substance and a reference substance are located. The analyte-specific substance is able to emit a first luminescence signal on contact with the analyte and the reference substance is able to emit a second luminescence signal which is substantially quenched by contact with the liquid sample.

A method of obtaining fluorochromes that bind to specific sites on proteins is presented. The method consists of synthesizing a peptide bearing a sequence from a parent protein and a second peptide of similar composition but with a scrambled sequence. Each peptide is then added to a test fluorochrome at similar concentrations, and a difference in fluorescence is obtained. A difference in fluorescence indicates a sequence dependent interaction between the peptide and fluorochrome. A large number of fluorochromes can be screened using the two peptides to find one binding in a sequence dependent fashion. This fluorochrome can then be tested for binding to the original full-length protein. The fluorochrome can then serve as scaffold in medicinal chemistry. The fluorochrome/peptide interaction and resulting fluorescence can be inhibited by non-fluorescent test compounds, which are compounds that bind to this peptide. Thus. the peptide/fluorochrome interaction can provide assays screening for therapeutic drugs binding to this site on the protein.
