Digital PCR Kits for cfDNA Quantification & ctDNA Detection

Digital PCR system costs vary widely by platform, throughput, and vendor, typically ranging from $30,000 to over $100,000 USD for instruments. Consumable kits like the OncoSeek cfDNA Extraction Kit are priced separately and available in 50-reaction packs.

Traditional PCR amplifies DNA and measures fluorescence relative to a standard curve, providing relative quantification. Digital PCR partitions the reaction into thousands of individual droplets or chambers, enabling absolute quantification without standards. Digital PCR is significantly more sensitive for detecting rare variants such as ctDNA mutations at low allelic frequencies, making it the preferred method for oncology liquid biopsy workflows.

The OncoSeek cfDNA Extraction Kit is optimized for plasma samples. It requires a minimum of just 1 mL of plasma — half the volume required by many competitors — while delivering 5–20× higher cfDNA yield. This is especially advantageous for pediatric oncology, limited-volume clinical samples, and longitudinal monitoring studies.

Yes. The OncoSeek cfDNA Extraction Kit uses bead-based purification that is fully compatible with automation platforms, including the Beluga automated liquid handler from Cambrian Bioworks. Automation reduces manual effort, minimizes variability, and enables consistent high-throughput cfDNA extraction in approximately 55 minutes per batch.

The extracted cfDNA is validated for use in Next-Generation Sequencing (NGS) library preparation, quantitative PCR (qPCR), and digital PCR including droplet digital PCR (ddPCR) workflows. The kit preferentially captures 150–200 bp tumor-derived cfDNA fragments, enriching ctDNA fractions for improved sensitivity in mutation profiling and minimal residual disease detection.

The OncoSeek cfDNA Extraction Kit is currently intended For Research Use Only (RUO) and is designed for oncology research and liquid biopsy applications. Cambrian Bioworks holds ISO 13485 certification and CDSCO IVD certification for its manufacturing operations.
