  • PROBER is a fast and sensitive episome-based method to identify sequence-specific DNA-binding proteins from living cells using proximity proteomics. This method quantifies steady-state and inducible association of transcription factors and corresponding chromatin regulators to specific DNA sequences as well as binding quantitative trait loci present as a result of single nucleotide variants.

  • Tardigrades are everywhere. They’re tiny — usually under a millimeter long — and they’re mostly transparent, so they’re easy to miss. But you probably walk by them every day. We’ve been grooming them as emerging models for studying how body forms evolve and how biological materials can survive extreme conditions.
