This specialized tube is designed exclusively for cell-free DNA (cfDNA) sample collection, storage, and extraction, with a core focus on preserving cfDNA integrity and ensuring high-quality extraction results. It integrates a unique buffer system (or inert inner coating, depending on product design) that effectively inhibits nuclease activity—one of the primary causes of cfDNA degradation—while preventing sample contamination from external nucleic acids or microorganisms.
Crafted from ultra-low DNA-binding medical-grade plastic, the tube minimizes non-specific adsorption of cfDNA to the tube wall, maximizing the recovery rate during extraction. Its airtight seal and chemical stability maintain sample conditions even during short-term room-temperature storage or transportation, eliminating the need for strict cold-chain logistics in most cases. Whether used for pre-analytical sample preservation or direct extraction workflows, the tube ensures cfDNA remains intact, pure, and suitable for downstream applications like next-generation sequencing (NGS) or digital PCR.
Key Features
Superior cfDNA Stability
Integrates nuclease inhibitors or protective buffers to block DNA degradation enzymes, keeping cfDNA intact for up to 72 hours at room temperature (or extended periods under refrigeration).
Maximized Sample Integrity
Ultra-low DNA-binding material reduces cfDNA loss from wall adsorption; sterile inner environment prevents cross-contamination, ensuring sample purity for accurate downstream testing.
High-Quality Extraction Support
Optimized tube design (e.g., smooth inner walls, compatible with standard extraction kits) streamlines cfDNA isolation, delivering higher yield and purity compared to general-purpose tubes.
Flexible Storage & Transportation
Chemical stability and airtight seal allow storage at 2°C–25°C (no strict cold chain required) and safe transportation, reducing logistics complexity and costs.
Compliant with Molecular Diagnostics
Meets ISO 13485 and other global molecular diagnostic standards, compatible with common cfDNA analysis workflows (NGS, PCR, digital PCR).
Applicable Testing & Research Fields
Clinical Molecular Diagnostics: Liquid biopsy (e.g., cancer early screening, tumor mutation detection, prenatal genetic testing) relying on cfDNA analysis. Biomedical Research: Studies on cfDNA biology (e.g., circulating tumor DNA, cell-free fetal DNA, cfDNA from bodily fluids like plasma or serum). Forensic Genetics: Low-input cfDNA sample processing for forensic identification or trace evidence analysis.
Clinical Labs & Hospitals: Molecular diagnostic departments conducting liquid biopsy or cfDNA-based disease detection. Biotech & Pharma Companies: R&D teams developing cfDNA-based diagnostic assays or therapeutic monitoring tools. Academic Research Institutions: Labs focused on hematology, oncology, or reproductive genetics research involving cfDNA.
