Significance of The Cell-free DNA Storage Tube

Cell-free DNA storage tube

Cell-free DNA storage tube is a disposable vacuum collection tube that can directly draw whole blood and stably store and transport free DNA (cfDNA), circulating tumor DNA (ctDNA) and nuclear cell genomic DNA at room temperature.

Product introduction

It is a disposable vacuum collection tube that can directly draw whole blood and be used for cell-free plasma DNA collection, stable storage and transportation. cf-DNA blood anticoagulant contained in blood tubes can stabilize nucleated blood cells to avoid the cleavage of white blood cells in blood, reduce the degradation of plasma DNA, and contribute to the overall stability of cell-free DNA. Free DNA samples can be stored at room temperature for up to 14 days, making sample collection, transportation and storage easier.

Product characteristics

The anticoagulants and cellular preservatives contained in the free DNA preservation tube can stabilize nucleated blood cells, prevent the release of cellular genomic DNA, inhibit nuclease-mediated degradation of cell-free DNA, and contribute to the overall stability of cell-free DNA. Noninvasive prenatal screening for mothers, which is accepted and recognized for its safety and accuracy, is the diagnosis of fetal genetic diseases through the detection and analysis of fetal free DNA in the mother's blood. The long-term preservation of samples of circulating tumor cells (CTC) in human blood creates conditions for early screening of tumors, and makes it possible to target tumors for treatment.

Product application

The Cell-free DNA storage tube has been widely used in many fields such as genetic research and biomedicine, such as fetal non-invasive birth defect screening (non-invasive Down test), tumor discovery and research, tumor treatment progress and efficacy evaluation research, acute molecular diagnosis and detection, clinical drug development and testing.

The specifications of Cell-free DNA storage tubes produced by Shengshi Dongtang are 5ml and 10ml.
