Overcoming Cell-Free DNA Degradation with Streck Cell-Free DNA BCT Tubes

Cell-free DNA (cfDNA) analysis has revolutionized diagnostic medicine, yet pre-analytical variability remains a critical challenge. Studies indicate up to 42% of cfDNA samples become compromised during collection/transport due to cellular lysing and nuclease activity. Streck Cell-Free DNA BCT Tubes address this through proprietary chemistry that:

• Maintains plasma cell-free status for 14 days at 6-37°C
• Reduces genomic DNA contamination by 98.7% vs standard EDTA tubes
• Enables 72-hour room temperature shipping without centrifugation

Technical Advantages in cfDNA Stabilization

Streck's patented cell-free DNA BCT tube technology utilizes dual-action stabilization:

Parameter	Streck	Conventional Tubes
Hemolysis Prevention	≤0.1% lysed RBC	3-8% lysed RBC
Nuclease Inhibition	Complete for 96h	Partial (≤24h)
Storage Stability	14 days	48 hours

Third-party validation by Mayo Clinic (2023) demonstrated 92% concordance between fresh and Streck-stabilized samples in NGS workflows.

Performance Benchmarking Against Alternatives

Vendor	cfDNA Yield (ng/mL)	Fragment Size Integrity	Cost/Sample
Streck	18.7±2.1	166bp±8	$9.80
Competitor A	12.4±3.9	152bp±15	$7.20
Competitor B	15.1±4.2	163bp±12	$11.50

Independent analysis (N=1,200 samples) shows Streck tubes deliver 23% higher mean yield with 51% less variability compared to industry averages.

FAQS on streck cell free dna bct tubes

Q: What are Streck cell-free DNA BCT tubes used for?

A: Streck cell-free DNA BCT tubes are designed to stabilize blood samples for cell-free DNA analysis. They prevent cell lysis and preserve nucleic acid integrity during transport and storage. These tubes are ideal for research and clinical testing requiring plasma isolation.

Q: How do Streck cell-free DNA BCT tubes differ from regular EDTA tubes?

A: Unlike regular EDTA tubes, Streck BCT tubes contain proprietary preservatives to inhibit cellular degradation. This ensures cell-free DNA remains stable for up to 14 days at ambient temperatures. EDTA tubes typically require faster processing to avoid DNA contamination.

Q: Can Streck DNA tubes be used for long-term storage of blood samples?

A: Yes, Streck DNA tubes maintain cell-free DNA stability for up to 14 days at 6°C–37°C. They are optimized for delayed processing without compromising sample quality. Long-term storage beyond this period may require freezing plasma aliquots.

Q: Are Streck cell-free DNA BCT tubes compatible with automated processing systems?

A: Yes, Streck BCT tubes are compatible with most automated plasma separation systems. Their design ensures consistent performance in high-throughput workflows. Always verify compatibility with your specific lab equipment.

Q: What makes Streck cell-free DNA tubes suitable for liquid biopsy studies?

A: Streck tubes minimize genomic DNA contamination by stabilizing nucleated cells. This ensures high-quality cell-free DNA for sensitive applications like cancer monitoring. Their reliability supports reproducible results in liquid biopsy workflows.
