ペプチドを結合蛍光タンパク質のDNAを用いた表面係留大型DNA分子の可視化

Executive Industry Relevance

Direct visualization of surface-tethered large DNA molecules using fluorescent protein DNA binding peptides (FP-DBP) enables precise interrogation of DNA-protein interactions at the single-molecule level. This capability supports early-stage target validation and mechanistic de-risking in biopharma discovery pipelines. The method enhances predictive confidence for downstream assay development and screening workflows.
