A new CRISPR method detects rare cancer mutations in blood with high sensitivity, aiding early diagnosis and treatment monitoring.
A new CRISPR-based technique called MUTE-Seq, developed by researchers at Korea University, enables highly sensitive detection of rare cancer mutations in blood samples, identifying changes present at as low as 0.005% variant allele frequency.
By using an engineered enzyme to remove normal DNA and enrich tumor-derived DNA, the method boosts mutation signals up to 60-fold, improving accuracy in detecting minimal residual disease and early-stage cancers.
It works with just 50 ng of DNA, is compatible with standard lab processes, and enhances the reliability of liquid biopsies for multi-cancer screening, treatment tracking, and resistance monitoring.
The approach was published in Advanced Materials in November 2025 and featured on the journal’s front cover.
