VanGenes® cfDNA Preservation Tube
Overview
VanGenes Cell-Free DNA preservation tube is a direct draw whole blood collection tube intended for collection, stabilization and transportation of cell-free DNA in plasma or serum and cellular genomic DNA present in nucleated cells.
It is widely used in the collection, transportation and storage of blood samples of pregnant women for Non-invasive Prenatal Test (NIPT) , Non-invasive Prenatal Paternity Test (NIPPT) and cancer early screening.
VanGenes cfDNA preservation tube has been registered with CIBG, Ministry of VWS, Netherlands. It complies with The European Commission’s (EC) In Vitro Diagnostic Regulation (EU IVDR 2017/746) and can be used for in vitro diagnostics in EU countries.
VanGens's manufacturing department's Quality Management System has been certificated by POSI against the provision of ISO13485:2016.
Advantage
- High Stability: Effectively avoids cfDNA degradation and genomic DNA release to maintain the concentration of cfDNA.
- High Tolerance: With VanGenes proprietary reagents, VanGenes cfDNA BTC preserves cfDNA for 14 days at 6~37℃ or 72 hours in shipment.
- Easy Downstream Operation: Extraction of plasma cfDNA and celluar genomic DNA can be accomplished using most commercially available kits.
- High-performance Reagent: Anticoagulant K3EDTA and VanGenes proprietary reagents added do not dilute blood samples.
- VanGenes cfDNA BTC is a CE marked In Vitro Diagnostic(IVD) device
- Wide Application: Liquid biopsies for oncology, infection, prenatal diagnosis, etc.

The right picture shows that ten blood samples from pregnant woman who carries male fetus were collected by using both VanGenes tube and a branded tube . The concentration of VanGenes tube was consistent with that tube.
The right picture above shows that the blood samples of pregnant women were collected by VanGenes cfDNA preservation tubes, which were stored at room temperature for 0/3/7 days. The concentration of fetal cfDNA was calculated by NIPT experimental analysis process. The results showed that VanGenes cfDNA preservation tube could stably store cfDNA in different storage time.
