BEAVER Cell Free DNA Tubes BEAVER Cell Free DNA Tubes are prepared by a special blood protection reagent in a vacuum blood collection tube. The protective reagent prevents blood coagulation and blood cell breakage, inhibits nuclease activity, protects cell surface antigens, maintains cell morphology, maintains blood component stability and also has other functions.
The detection of nucleic acid components in animal blood, especially the detection and analysis of circulating DNA in plasma (cfDNA), is an important field in current disease diagnosis methods. The study found that only a very small amount of cfDNA was found in healthy plasma samples. (Approximately 5-30 ng/ml), an increase of peripheral blood cfDNA levels is associated with many clinical disease occurrences.
