Abstract
The invention discloses a blood collection tube for protecting and stabilizing free DNA. The blood collection tube comprises a test tube, a sealing capsule and a protective agent. After blood is collected into the blood collection tube, the blood is shaken up and down ten times to be sufficiently and evenly mixed and then is preserved at room temperature. The blood free DNA can be protected for as long as 14 days at normal temperature, and the blood collection tube can be used for protecting and storing the blood free DNA.
Description
Technical field
The present invention relates to a kind of protection and the heparin tube of stabilization dissociative DNA.
Background technology
Free nucleic acid is earliest to be found by Mandel and Metais in nineteen forty-seven, but special due to lacking high sensitivity and height
The experimental technique of property, causes to be made slow progress within the longer term with disease associated research about dissociative DNA in blood.Until
The appearance and application of dissociative DNA technology, PCR detection techniques are efficiently separated, the research in this field was obtained at nearest more than 20 years
To relatively developing rapidly.After dissociative DNA can contain the mutation of DNA of tumor cell homologous genes in self-discovery blood, using molecular biosciences
Learning to do section increasingly increases the interest for circulating the research of free nucleic acid.But these free DNA in conventional heparin tube very
Easily just degraded disappears, therefore the heparin tube of a kind of protection and stabilization dissociative DNA is in demand.
At present, various heparin tubes are there are on the market, and all simply being played in these heparin tubes prevents blood clotting
Effect, without play a part of protect free nucleic acid.In CC, due to the limitation of condition or time, it is impossible to
Very first time separated plasma after blood is obtained, the cell rupture and prolonged unprotect exposed state in blood can cause blood
In the DNA degradation that dissociates, cause that the false negative of subsequent experimental or experimental result cannot be carried out, so as to cannot provide valuable for clinical
The information of value.
In view of this, the heparin tube of a kind of protection and stabilization dissociative DNA is invented herein, to reduce what subsequent survey was detected
Interference.
The content of the invention
A kind of heparin tube it is an object of the invention to manufacture protection and stabilization dissociative DNA, the heparin tube can not only be prevented
Blood clotting, and can protect and stablize wherein free DNA.The heparin tube is by test tube, seal rubber plug and protective agent group
Into.By blood collection to Guan Zhonghou, turning upside down 10 times, it is uniform to be sufficiently mixed, room temperature preservation.So that the dissociative DNA in blood
Can preserve at normal temperatures 14 days.
Main technical points of the invention are as follows：A kind of protection and the heparin tube of stabilization dissociative DNA, described heparin tube
It is to be fabricated by by PET's material of hydrophobic property, described seal rubber plug is manufactured by butyl rubber material
Form, described protective agent is formed by the dissolving of the material such as fourth EDTA-3K, IDU, glycine, bestain, AEBSF, concentration
Respectively 50g/L, 550g/L, 30g/L, 1mg/L, 0.172g/L, 0.24g/L.
In the application, by blood collection to Guan Zhonghou, turning upside down 10 times, it is uniform to be sufficiently mixed, room temperature preservation for the present invention.
Fig. 1 is composition structural representation of the invention.1 refers to test tube, and 2 refer to seal rubber plug, and 3 refer to protective agent.
Fig. 2 is that whole blood sample carries out 0,3,7,14 in the heparin tube of a kind of protection of the present invention and stabilization dissociative DNA
The testing result of its rear stability.
Fig. 3 is whole blood sample in conventional EDTA-Na20,3,7,14 days testing results of stability are carried out in heparin tube.
Specific implementation method
Following case study on implementation is only used for explaining the present invention, rather than the limitation present invention.
Example：
Blood sample is randomly selected simultaneously with heparin tube of the present invention and routine EDTA-Na2 heparin tubes, each blood sample extracts 4 pipes respectively, often
Temperature place 0 day, 3 days, 7 days, after 14 days carry out nucleic acid extraction（The QIAamp DNA Blood Mini Kit of Qiagen companies
(50)-kit of article No. 51104）, enter the real-time PCR detection of pedestrian's β-ACTB genes as sample with the nucleic acid for extracting.
Testing result：
It is placed in conventional EDTA-Na2The whole blood sample of the heparin tube of heparin tube and protection of the present invention and stabilization dissociative DNA,
After room temperature different time, nucleic acid extraction is carried out respectively, the nucleic acid of extraction enters the real-time fluorescence PCR of pedestrian's β-ACTB genes
Detection, the Ct values such as table 1 of its testing result.
Table 1
As shown in Table 1, the heparin tube of a kind of protection of the present invention and stabilization dissociative DNA can effectively be protected in 14 days
With stablize blood middle reaches from DNA, only extremely slight degraded；And routine EDTA-Na2The stability of heparin tube is excessively poor,
Degraded situation is extremely serious.
Fig. 2 and Fig. 3 is the real-time PCR detection result figure of the corresponding people β-ACTB genes of table 1, and wherein Fig. 2 is for herein
A kind of described protection and the heparin tube of stabilization dissociative DNA carry out 0,3,7,14 days testing results of stability, as seen from the figure,
In the detection time of 0 ~ 14 day, all detection samples are all correctly detected, and are had good stability, and the free nucleic acid in blood is obtained
It is effectively protected；Fig. 3 is routine EDTA-Na20,3,7,14 days testing results of stability, testing result are carried out in heparin tube
It has been shown that, conventional EDTA-Na2The stability of the free nucleic acid in heparin tube is excessively poor, and degraded situation is extremely serious.
