  • Publication number: 20180172678
    Abstract: Methods, systems and nanoprobes for identifying sequence-specific transcription factor DNA interactions for drug and/or disease screening are provided. The method includes homogeneously mixing plasmonic metal nanoparticle probes with protein samples as an assay in multi-well plates. The plasmonic metal nanoparticle probes comprise a plurality of plasmonic metal nanoparticles and a specific DNA response element and the protein samples bind with the specific response elements to form an assembly of the plasmonic metal nanoparticle probes. The method further includes measuring particle size distribution of the assembly of the plasmonic metal nanoparticle probes in the solution by dynamic light scattering and determining one or more sequence-specific transcription factor DNA interactions from a curve of the particle size distribution determined from light scattered by the dynamic light scattering. The nanoprobe includes a plurality of plasmonic metal nanoparticles and a DNA linker.

  • Publication number: 20150276755
    Abstract: The present disclosure provides a method of determining resistance of a biological molecule to inhibition of its interaction with a target molecule by an inhibitor of the biological molecule, the method comprising the steps of: a) co-compartmentalizing a gene encoding the biological molecule with the target molecule, or a gene encoding the biological molecule with a gene encoding the target molecule into an aqueous droplet disposed within a water-in-oil emulsion, and b) assaying for a complex comprising the biological molecule and the target molecule upon expression of the gene encoding the biological molecule and the gene encoding the target molecule, wherein detection of the complex in the presence of the inhibitor indicates that the biological molecule is resistant to inhibition of its interaction with the target molecule by the inhibitor. Also provided are mutated HDM2 ubiquitin ligase polypeptides exhibiting resistance to Nutlin inhibition of p53 binding.
