Product Description
Cell-Free DNA Collection TubeProduct DescriptionThe Cell-Free DNA Collection Tube is applicable to the preservation of cell-free DNA (cfDNA) / circulating tumor DNA (ctDNA) and the preservation of circulating tumor cells (CTC).Also,it is applicable to the collection, transportation, storage and processing of clinical whole blood samples.FeaturesUnder the conditions of 4ºC to 30ºC, the cf-DNA in the samples within the tube can remain stable for at least 14 days.Under the conditions of 4°C to 30°C, the CTCs (circulating tumor cells) in the samples within the tube can remain stable for at least 7 days.When transported under the conditions ranging from 4°C to 30°C, the cf-DNA in the samples inside the tube can remain stable for at least 7 days.Product PrincipleGeneway.bio Cell-Free DNA Collection Tube is a kind of sterile vacuum tube. The additives it contains can prevent blood from clotting, cell lysis, and protect cell-free nucleic acids from being degraded by nucleases. During the transportation and storage of whole blood, the lysis of nucleated cells, which releases gDNA (genomic DNA), can seriously affect the accuracy of the analysis of the target cell-free DNA. Moreover, research has shown that the cell-free nucleic acids in the blood will degrade rapidly under the action of nucleases 36 hours after the whole blood leaves the body. The additives in the blood cell-free nucleic acid preservation tube can maintain the integrity of red blood cells and nucleated cells in the blood, inhibit their cellular metabolism to stabilize the cells, and prevent the release of gDNA during the transportation and storage of samples. Meanwhile, it also ensures the integrity of CTCs (circulating tumor cells), facilitating downstream processing and analysis. The additives also contain components that inhibit nucleases, thereby suppressing the activity of nucleases in the blood and preventing the degradation of cell-free nucleic acids in the plasma during transportation and storage.Specifications| Material | Volume | Specifications | Shelf Life |
