• Excellent Stability: The tubes contain a preservative solution with EDTA anticoagulant and unique protective agents. It can effectively inhibit plasma nucleases and prevent the release of genomic DNA from blood nucleated cells. The CF-DNA can be stably preserved for up to 14 days at 6-37°C, facilitating sample collection, transportation, and testing.
• Maintaining Sample Integrity: They prevent the release of intracellular nucleic acids into the plasma, avoiding contamination of cell-free DNA. Also, they protect cell-free DNA from degradation and cross - linking with other substances. These tubes help maintain sample integrity during storage and transportation, ensuring accurate test results by minimizing circulating tumor cell degradation
• Wide Applicability: They are suitable for various applications, including preserving circulating tumor cells and DNA in liquid biopsies for cancer research, and fetal cell-free DNA in non - invasive prenatal testing. These tubes also support the isolation and extraction of blood microbial DNA, plasma cell-free DNA, and blood nucleated cells for downstream experiments, thus bolstering disease diagnosis, drug development, and clinical studies
• High-Quality DNA Extraction: DNA extracted from samples in these tubes using commercial kits is of high purity and quality, meeting the requirements of downstream analyses like high-throughput sequencing and qPCR
• User-Friendly: They allow direct blood sample collection and transportation without complex pretreatment, simplifying workflows, improving efficiency, and reducing demands on operators
