Detecting rare mutations requires analytical methods with exceptional sensitivity and precision.

Droplet digital PCR (ddPCR) has emerged as a powerful technology for quantifying low-frequency genetic variants, making it well suited for applications such as minimal residual disease (MRD) assessment and mutation monitoring. This white paper presents a performance evaluation of a ddPCR assay for detecting rare BRAF V600E mutations in bone marrow and peripheral blood mononuclear cell (PBMC) samples, demonstrating its analytical sensitivity, accuracy, and reproducibility.

Key topics include:

• Analytical validation of a ddPCR assay for detecting rare BRAF V600E mutations
• Performance evaluation using bone marrow and PBMC sample matrices
• Assessment of analytical sensitivity, limit of detection, precision, and accuracy
• Applications of ddPCR for rare mutation detection, minimal residual disease (MRD), and oncology research

The study demonstrated a limit of detection of 0.01% variant allele frequency (VAF) and consistent performance across validation studies, supporting the use of ddPCR as a reliable approach for detecting low-frequency mutations in hematologic research and investigational clinical applications.
