Cell-free DNA storage at room temperature and large-volume machine extraction so

Product Description:

The content of cell-free DNA in blood is very small, and it is easily degraded without processing after sampling. Clinical projects such as non-invasive prenatal screening (NIPT) for pregnant women, early screening of tumors, and precise medication guidance all require the detection and analysis of cell-free DNA. The preservation, enrichment and extraction effects of cell-free DNA will directly affect the accuracy of back-end detection. AJcore's plasma cell-free DNA storage tube (NA-001-T) is used for sampling and storage at room temperature, and a pre-packaged large-volume plasma cell-free DNA extraction kit (NA-001-Y) is used combined with an eight-channel large-volume nucleic acid extraction instrument. (AJPure08) to complete the automated enrichment and extraction of plasma free DNA, which can obtain high-purity free DNA. The enriched and extracted products can be directly used in various PCR, gene sequencing, molecular hybridization and other experiments.

Product Features

1. NA-001-T plasma free DNA storage tube at room temperature contains a special cell protective agent, which can effectively inhibit nuclease in the blood and prevent the rupture of blood cells. Free DNA can be stably stored at room temperature for 14 days
2. NA-001-Y plasma cell-free DNA extraction reagent is packaged in pre-packaged reagent strips. It is safe and non-toxic. The standard sample loading volume is 2 ml
3. The AJPure 08 nucleic acid extractor is easy to operate and can complete the automated enrichment and extraction of 8 samples in 40 minutes

Experiment Data

Example of results

Use AJPure08 nucleic acid extractor and AJcore plasma free DNA extraction kit to extract 2 ml of plasma from different people (the curves shown are the results of PCR amplification of purified free DNA from different samples). The Ct values of different samples are all high, and the extraction performance Stablize.

 

AJcore plasma cell-free DNA storage tubes at room temperature were extracted and purified using AJPure 08 nucleic acid extractor and AJcore plasma cell-free DNA extraction kit at different storage days (1 day, 3 days, 5 days, 9 days, 14 days) and then subjected to PCR amplification. As the storage time increases, the total amount of free DNA in the storage tube is relatively stable.
