Researchers developed new technologies for chemical genetics, enabling large-scale screening of small molecules to study biological pathways. This platform facilitates efficient compound synthesis and assaying for diverse chemical genetic experiments.

Area of Science:

  • Chemical biology
  • Molecular biology
  • Synthetic chemistry

Background:

  • Chemical genetics utilizes small molecules to investigate biological processes, necessitating extensive and varied chemical libraries.
  • Perturbing specific biological pathways requires precise tools for chemical library screening.

Purpose of the Study:

  • To develop and present an integrated technology platform for chemical genetics.
  • To enable the screening of chemical libraries synthesized via split-pool solid-phase synthesis in various chemical genetic assays.

Main Methods:

  • Compounds synthesized on high-capacity polystyrene beads using split-pool solid-phase synthesis.
  • Bead arraying into 384-well plates, followed by compound cleavage and nanoliter-scale transfer using robotic systems.
  • Development of reusable silicone rubber assay plates (1536- and 6144-well) for laboratory casting and manual filling.
