Latest Publications

Here are a few publications from the Sexton laboratory that show the kinds of projects and technologies that we use.

Nuisance compounds in cellular assays

Compounds that exhibit assay interference or undesirable mechanisms of bioactivity (‘‘nuisance compounds’’) are routinely encountered in cellular assays, including phenotypic and high-content screening assays. Much is known regarding compound-dependent assay interferences in cell-free assays. [...]
