Key Features

1. 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).
2. 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.
3. 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.
4. 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.
5. 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.
