| 20100203572 | METHOD FOR CARRYING OUT AND EVALUATING MIX & MEASURE ASSAYS FOR THE MEASUREMENT OF REACTION KINETICS, CONCENTRATIONS AND AFFINITIES OF ANALYTES IN MULTIPLEX FORMAT - The invention relates to a method comprising the following steps: a) use of a support which has at least two different microparticle populations immobilized thereon; b) measuring the fluorescence of the support from step a) with an optical resolution 1, said resolution 1 permitting differentiation of microparticle singlets, doublets, triplets, multiplets and monolayers and determination of the localized position of individual immobilized microparticles; c) contacting the support from step a) with the sample to be analyzed; d) performing at least one additional measurement of the fluorescence of the support during or after contacting in accordance with step c) with a resolution 2; e) assigning the fluorescence values measured with resolution 2 to the individual microparticle singlets, doublets, triplets, multiplets and monolayers locally identified on the support in accordance with step b) and assigned to a particular acceptor molecule population; f) determining the change in fluorescence. The method is used to determine reaction kinetics, concentrations and affinities of analytes in samples. | 08-12-2010 |
