Statistical evaluation of a self-deconvoluting matrix strategy for high-throughput screening of the CXCR3 receptor.

In high-throughput screening (HTS), compounds can be tested in self-deconvoluting matrices (SDMs) of 10 compounds per well. The SDM setup is based upon a systematic mixing of compound samples such that each compound appears twice in the screening assay, in two independent mixtures. In order to test the quality of the SDM approach, we compared it with a standard single-compound screening approach. In a CXCR3 scintillation proximity assay, we performed five multiple screening trials of 26,400 compounds at a 10 microM screening concentration to estimate false positive and false negative rates in the compound population.
