The PAXgene Blood ccfDNA Tube is a tube specifically designed for the preservation and stabilization of circulating cell-free DNA (ccfDNA) in blood. This product has the following features:
High-quality preservation of ccfDNA
The PAXgene Blood ccfDNA Tube stabilizes circulating cell-free DNA (ccfDNA) immediately after blood collection, allowing samples to maintain high quality over an extended period. This stability prevents DNA degradation and ensures the accuracy and consistency of downstream analyses.
Non-invasive sample collectio
This method is simple, convenient, and places minimal burden on the patient. Compared with traditional invasive sampling methods, obtaining ccfDNA through a blood draw is safer and more acceptable, making it particularly suitable for repeated sampling or long-term monitoring.
Enhanced reliability in analysis
Blood samples preserved in this tube provide significantly improved reliability and reproducibility when performing ccfDNA analysis, which is critical for various molecular diagnostic techniques such as:
- Next-Generation Sequencing (NGS)
- Polymerase Chain Reaction (PCR)
By maintaining sample integrity, the tube reduces technical variation, resulting in more accurate test results and more dependable data for clinical and research applications.
Primary applications
The PAXgene Blood ccfDNA Tube is widely used in both clinical and research settings, including:
- Liquid biopsy for cancer
Detection and monitoring of tumor DNA to enable non-invasive diagnosis and treatment assessment. - Prenatal diagnostics
Detection of fetal DNA from maternal blood for non-invasive prenatal testing (NIPT) or other genetic analyses. - Post-transplant monitoring
Monitoring circulating DNA in transplant patients to help detect graft-versus-host disease (GVHD) or to evaluate transplant outcomes.
Intended users
This product is primarily designed for researchers and healthcare professionals who require high-quality, reliable data from blood samples to support precision diagnostics, disease research, and the advancement of personalized medicine.
