Detecting analytes in a sample uses determination cycles using immobilized receptors

摘要

Detecting analytes (A) in a sample uses determination cycles using immobilized receptors. Detecting analytes (A) in a sample uses determination cycles using immobilized receptors. (A) comprises: (a) carrying out a first detection cycle comprising: (i) providing a carrier with distinct areas comprising immobilized receptors which are each specific for a different analyte; (ii) contacting the sample with the carrier, and (iii) identifying the areas in which binding occurred; (b) carrying out a second determination cycle, comprising: (i) providing another carrier with distinct areas comprising immobilized receptors which are each specific for a different analyte, but the receptors are chosen according to the results of the first carrier binding, where the receptors and/or the binding conditions are varied; (ii) contacting the sample with the carrier, and (iii) identifying the areas in which binding occurred; and optionally (c) carrying out further determination cycles to obtain sufficient information.
