Digital PCR Systems & Cost: dPCR Platform Comparison for Liquid Biopsy

Standard qPCR machines range from $5,000 to $30,000, while digital PCR platforms typically cost $30,000 to $90,000 or more. Beyond the instrument, per-run consumable and sample prep costs are significant. Automated, cartridge-based extraction kits help reduce hands-on labor and reagent waste, lowering the total cost of each dPCR experiment substantially.

Digital PCR liquid biopsy workflows commonly use plasma-derived cfDNA, whole blood gDNA, FFPE tissue gDNA, and RNA from blood or FFPE. Cambrian Bioworks offers dedicated extraction kits for all these sample types, each optimized to deliver high-purity, high-yield nucleic acids ready for direct input into dPCR assays without additional cleanup steps.

Digital PCR detects rare mutant alleles at frequencies as low as 0.01%, so template purity and yield directly determine assay sensitivity. The OncoSeek cfDNA Extraction Kit preferentially captures 150–200 bp tumor-derived fragments and minimizes genomic DNA contamination, ensuring your dPCR reactions are not diluted by non-target DNA that can mask low-abundance ctDNA signals.

The OncoSeek cfDNA Extraction Kit completes bead-based purification in approximately 55 minutes from just 1 mL of plasma. The Cambrian Whole Blood gDNA Isolation Kit processes samples in under 30 minutes. Both workflows are automation-compatible on the Manta platform, significantly reducing hands-on time before your digital PCR run begins.

Yes. All Cambrian Bioworks extraction kits are designed for automation on the Manta cartridge-based platform, processing 1 to 32 samples per run. Pre-filled, non-reusable cartridges eliminate manual reagent dispensing and prevent cross-contamination, making them ideal for high-throughput digital PCR workflows in clinical oncology and research settings.

Yes. The OncoSeek cfDNA Extraction Kit is explicitly optimized for ddPCR, qPCR, and NGS workflows. Performance is validated using TapeStation cfDNA ScreenTape analysis, and the kit consistently delivers cfDNA of sufficient purity (minimal gDNA contamination) and quantity to meet the stringent input requirements of digital PCR-based ctDNA detection assays.
