BioImage last week launched two new assays that use the company's Redistribution technology: a ß-Catenin Redistribution assay and a Rad51 Redistribution assay.
According to BioImage, the ß-catenin Redistribution assay is designed to assay for antagonists of ß-catenin translocation by monitoring the translocation of a GFP-ß-catenin fusion protein from the membrane to the nucleus. The Rad51 assay is designed to assay for compounds inducing replication-associated DNA double-stranded breaks, as such compounds lead to accumulation of the Rad51-GFP fusion protein in foci within the nucleus.
