BunnyTube Cell-free DNA Preservation Tube

BunnyTube Cell-free DNA Preservation Tube contain a special stabilizer that immobilizes blood cells after collection to prevent the release of genomic DNA and inhibit the degradation of cfDNA by nucleases to maintain the overall stability of cell-free DNA. It is used for the collection, transport and storage of cell-free DNA from blood samples for clinical testing.

BunnyTube Cell-free DNA Preservation Tube

Product Description

The role of plasma cell-free DNA (cfDNA) is becoming increasingly evident as an important test sample for tumor diagnosis and non-invasive prenatal screening. BunnyTube Cell-free DNA Preservation Tube can be directly used for whole blood collection, preservation and transportation, which can effectively protect cfDNA from degradation by nucleases and avoid the release of genomic DNA from blood nucleated cells, greatly ensuring the downstream application of cfDNA.

This product uses EDTA anticoagulant and special protective agents to stably preserve cell-free DNA in blood for up to 14 days at 6-35°C. Preserved blood samples can be used to most commercial kits for cfDNA extraction to meet the needs of research and in-vitro diagnostic applications.


Product Advantage

  1.  High Stability: Effectively avoids cfDNA degradation and genomic DNA release.

  2.  High Tolerance: Good temperature tolerance for easy storage and transport of samples.

  3.  Excellent Sequencing: The extracted cfDNA has excellent library preparation efficiency and sequencing quality.

  4.  Wide Application: Designed for liquid biopsies for oncology, infection, prenatal diagnosis, etc.


Experimental Data

采血管1

Figure 1. Hemolysis of blood samples and stable cfDNA yield at different storage times.

Blood samples were collected into 3 brands of preservation tubes, and the samples were placed at room temperature for 0, 3, 7 and 14 days to compare the hemolysis and cfDNA yield. BunnyTube Cell-free DNA Preservation Tube could effectively inhibit hemolysis and the extracted cfDNA yield was stable.

Figure 2. Hemolysis of blood samples and stable cfDNA yield at different transport temperatures.

The blood samples were collected into 3 brands of preservation tubes, and samples were compared for hemolysis and cfDNA yield after 0 days at room temp, 3 days at room temp (25℃), high temp (35℃) and low temp (4℃) transportation. BunnyTube Cell-free DNA Preservation Tube can withstand different transportation temperatures and have better resistance to genomic nucleic acid release.
