CellProBio Cell-free DNA storage tube

Principle of action:

The DNA tube additive consists of an EDTA anticoagulant and a special protectant. Anticoagulants prevent blood samples from clotting. The protective agent not only prevents the degradation of free DNA and prevents the blood nucleated cells from rupturing to produce gDNA contamination, but also effectively maintains the stability of blood components without cross-linking reactions.

Product advantages

The self-developed protective agent can effectively inhibit the degradation of free DNA, protect the integrity of red blood cells and white blood cells, and maintain the stability of blood components.

• After collecting blood samples, free DNA can be stored at room temperature for up to 14 days and transported for 7 days.
• Compared with the same type of products, the amount of plasma obtained increased by 10 ~ 20%, and the proportion of 50 ~ 250bp free DNA fragments was higher.
• Aluminum foil vacuum packaging improves the performance protection of additives and ensures the stability of the product during the validity period.
• Personalized customization

Clinical application

It is used for blood collection, storage and transportation and can stably protect free DNA in blood samples. Free DNA sample preservation tube blood samples can be extracted according to most commercial kits, and the extracted free DNA can be applied to downstream detection and analysis, such as non-invasive prenatal screening and tumor liquid biopsy and other diseases of scientific research. At the same time, the product can also be used for the preservation of nucleated cells and CTCs in the blood.
