A process for carrying out a specific binding assay, for the qualitative detection or quantitative or semi-quantitative determination of an analyte which forms a component of a specific binding reaction, using a labelled conjugate form of a derivative or analogue of one of the relevant specific binding partners, said labelled form being capable of emitting delayed luminescence upon photo-excitation, characterised in that the labelled conjugate form of one of the relevant specific binding partners comprises a derivative or analogue of the specific binding partnerwith a derivative of a luminescent substance which shows a delayed light emission upon photoexcitation, the delayed light emission of which is subject to quenching by molecular oxygen, and characterised further in that the assay is carried out by the use of a time-resolved photometric method in the presence of an effective amount of a quench-inhibiting substance able to prevent quenching by molecular oxygen.
