Does it bind? An instant binding assay for DNA oligonucleotide interactive small molecules

Abstract

Ultrafiltration analysis has been used to screen DNA oligonucleotide interactive small molecules for the first time, providing an almost instantaneous indication of the binding affinity, and was used to identify a new class of DNA interactive molecules based on a range of dihydro-imidazo-phenanthridinium-based framework; this methodology provides a straightforward yes/no answer to small molecule DNA binding.
