Executive Industry Relevance

Replication fork stalling at structure-prone DNA repeats presents a critical challenge for predictive confidence in early drug discovery, particularly when targeting genome stability pathways. Two-dimensional gel electrophoresis enables direct visualization of replication intermediates, supporting mechanistic de-risking and target validation for therapeutic programs addressing repeat-associated disorders. This capability informs portfolio decisions by clarifying the biological impact of sequence-specific replication impediments.
