Cell-free DNA Storage Tubes are engineered for stabilizing circulating cell-free DNA (cfDNA) samples, playing a pivotal role in liquid biopsy and precision medicine.
Preserving cfDNA Integrity:
➤ Inhibits nuclease degradation, preventing fragmentation
(especially critical for <160bp ctDNA fragments)
➤ Eliminates genomic DNA contamination to ensure detection
specificity
Enabling Precision Diagnostics:
➤ Provides high-quality samples for cancer early screening (e.g.,
lung/CRC), NIPT, and transplant rejection monitoring
➤ Supports high-sensitivity assays (NGS, dPCR)
| Feature | Technical Advantage |
|---|---|
| Chemical Stabilization | Proprietary stabilizer enables 7-14 days room-temperature storage, eliminating cold chain requirements |
| Nuclease Barrier | Tube-wall coating blocks nuclease activity (>95% cfDNA fragment retention, 40% improvement vs. EDTA tubes) |
| Ultra-Low Binding | Inert interior surface minimizes cfDNA loss (adsorption rate <0.5%) |
| Regulatory Compliance | ISO 13485 certified, compatible with automated extraction systems |
Operational Advantage: Direct blood transfer without pre-centrifugation; compatible with -80°C long-term storage
