Key Features of Cell3™ Preserver
Enhanced Blood Sample Stability
Cell3™ Preserver collects and stabilizes whole blood at room temperature for 15 days, eliminating the need for immediate processing or cold chain logistics. Ideal for long-distance transport or unexpected delays.
Suitable for Advanced Applications
- Non-Invasive Prenatal Testing (NIPT)
Maintains fetal DNA fraction consistency, enabling accurate detection of chromosomal abnormalities (e.g., trisomy 21, monosomy X). - Liquid Biopsy
Preserves ctDNA integrity for reliable cancer mutation detection in metastatic patients. - Compatibility
Works with qPCR, DNA fragment analysis, whole-genome sequencing, and targeted sequencing platforms.
Designed for Safe Handling
- Plastic Evacuated Tube
Durable, disposable, and compatible with standard blood collection systems. - Reduced Contamination Risk
Minimizes pre-analytical variability for consistent results.
Validated on Multiple Platforms
Performance has been validated across various methodologies, including qPCR, DNA fragment analysis, and NGS (whole-genome and targeted sequencing). Results show performance equal to or better than other products in the market.
NIPT
Blood samples from five patients stored in Cell3™ Preserver and a competitor’s tube (Company S) were analyzed:
- Accurate Results
Correctly identified fetal chromosomal abnormalities, including monosomy X and normal karyotypes - Fetal Fraction Consistency
Cell3™ Preserver showed stable fetal DNA levels at Day 5 and Day 11, matching Company S’s performance at Day 5 (Figure 1)

Liquid Biopsy
Blood samples from metastatic breast cancer patients post-chemotherapy preserved in Cell3™ Preserver and Company S’s tube were compared:
- Pathogenic Variant Detection
Both tubes identified two therapeutic-relevant mutations in ctDNA and FFPE tumor tissue, absent in germline DNA - Variant Frequency Correlation
Cell3™ Preserver matched competitor performance in mutation detection accuracy (Figure 2)
