Cell Free DNA Tubes

BEAVER Cell Free DNA Tubes are prepared from specially formulated blood protective agents pre-packed in vacuum blood collection tubes. The protective agents can prevent blood coagulation and blood cell fragmentation, inhibit nuclease activity, protect cell surface antigens, maintain cell morphology, and maintain blood circulation. Ingredient stability and other functions.

The detection of nucleic acid components in animal blood, especially the detection and analysis of cell-free DNA (cfDNA) in plasma, is an important field in current disease diagnosis methods. Studies have found that there is only a very small amount of cfDNA (about 5-30ng/ml) in healthy plasma samples, and increased levels of cfDNA in peripheral blood are related to the occurrence of many clinical diseases. Under normal conditions, during the collection, storage and transportation of fresh blood, nucleated cells in the blood are easily broken and release cellular genomic DNA and other components, causing the free DNA components in the plasma to be contaminated or affected by nuclease-mediated degradation. , the solution to this problem has always been one of the important aspects of preprocessing of such biological samples.

This product can be directly used for animal blood collection. After the blood sample is fully mixed with the pre-installed protective agent, it can be stably stored at 6-37°C for 14 days, which can better meet the researchers' needs for short-term storage and transportation of blood samples. It provides guarantee for the isolation and extraction of blood microbial DNA, plasma cell-free DNA, blood free nucleated cells and other samples and other follow-up experiments.

Note: This product can only be used for scientific research and not for medical diagnosis.

Data:

Compared with imported products, free DNA was extracted from peripheral blood samples of pregnant women collected and stored by BEAVER Cell-Free DNA Tubes, and then library construction and sequencing were performed.
The results showed that the sequencing results were stable and normal, and the GC content was normal, which was consistent with the test results of imported competitive products. As shown below.

Cell-free DNA was extracted from blood samples stored in beaver cell-free nucleic acid storage tubes and then library construction and sequencing were performed. The results showed that the sequencing results were good and the GC content was normal, which was basically consistent with the test results of foreign competitive products.
