Desheng develops and produces a variety of nucleic acid detection materials to choose from
Recently, the new crown virus has been raging in Fujian, Heilongjiang and other places, causing the epidemic that should have been alleviated to enter a moment of emergency again. The strain that spreads the epidemic is the Delta mutant strain, which has a strong spreading ability and a fast spreading speed, coupled with the particularity of the place where the current round of the epidemic occurred, which has also led to a further expansion of the spread. In response to this epidemic, Desheng adheres to the spirit of "watching for each other and helping each other, and we will provide raw virus transport medias to enterprises in the epidemic area as soon as possible. We will do our part to provide strong support for epidemic prevention and control related testing.
In addition to the virus transport media that plays a direct role in nucleic acid detection, Desheng develops and produces a variety of products that are used in the raw materials for nucleic acid detection.
Tris(hydroxymethyl)aminomethane (TRIS) is an important biological buffer, which is widely used in the preparation of buffers in the fields of biochemistry and molecular biology. Since nucleic acids (DNA, RNA) are easily hydrolyzed in acidic solutions, they are more stable in neutral or weakly alkaline solutions. The pH buffer range of TRIS: 7.0-9.0, can maintain the stability of the nucleic acid released after the lysis of the sample to be extracted, so as to avoid the degradation of the nucleic acid and improve the concentration and purity of the nucleic acid.
EDTA is ethylenediaminetetraacetic acid, which can combine with metal ions such as Mg2+, Ca2+, Mn2+, Fe2+, and can prevent metal ions from activating proteases, thereby reducing the impact of metal ions on nucleic acid quality.
Proteinase K can degrade histones that are tightly bound to nucleic acids, separate DNA and proteins, so that DNA can be better extracted; in addition, proteinase K can degrade RNA hydrolase (RNase) activity, inhibit RNase hydrolysis of template RNA, and is used in RNA extraction And it plays an indispensable role in the detection process, so the significance of proteinase K in the new crown detection is very important.
The HEPES buffer is also contained in the non-inactivated virus storage solution. It maintains the pH value and increases the survival time of the virus host cell in vitro after sampling. It retains the integrity of the viral nucleic acid and protein to a large extent, improves the accuracy of detection, and inactivates the virus. TRIS is generally used as a buffer in live virus transport medias.
The development of an enterprise is inseparable from the support of national policies and social forces. It is the responsibility of the enterprise to return to the society, and it is the requirement and embodiment of the entrepreneurial spirit in the new era. Since its establishment in 2005, Desheng Technology has been adhering to the value orientation of morality, integrity, innovation, cooperation, and win-win, and has closely linked the company's own development with social responsibility.
On the one hand, Desheng is committed to the research and development of high-end biological buffers, in vitro diagnostic reagent materials, chemiluminescence reagents, and blood collection tube additives. With pioneering and innovative spirit and perseverance, it promotes the steady development of the company and enhances its value. Provide employees with a safe and reliable development platform, and provide customers with high-quality, convenient, and more cost-effective diversified products and services. On the other hand, Desheng actively fulfills its social responsibilities and responsibilities, takes the corporate culture as the guide, practices social welfare, and feeds back the society with practical actions and outstanding performance.
In today's medical field, heparin lithium plays an indispensable role. Heparin lithium is a blood anticoagulant widely used in blood collection and blood gas detection. As a high-tech enterprise specializing in heparin lithium, Desheng's products are widely used in the field of medical diagnosis.
