Principles and advantages of agarose gel electrophoresis Agarose gel electrophoresis is an electrophoretic method using agar or agarose as a supporting medium. For samples with larger molecular weights, such as macromolecular nucleic acids, viruses, etc., agarose gel with larger pore size can generally be used for electrophoretic separation.

What kind of blood coagulant is good for coagulation? Blood coagulant is one of the core additives in vacuum blood collection tubes. The quality of the coagulant directly affects the coagulation effect of the separation gel-promoting tube, and the amount of use is large, the technical requirements are high, and the technical performance is very critical. It represents the true technical level of the enterprise in the vacuum blood collection tube industry, so it is very important to choose the appropriate coagulant.

The secret of coagulant between blood collection tube and blood The speed of medical tests is of great clinical significance. Some tests require the separation of serum from blood concentration in order to perform. It usually takes one hour from blood clotting to hemorrhage extraction. Even if heated centrifugation is used, it takes half an hour, and it is easy to cause hemolysis. In case of emergency blood distribution or emergency diagnosis, delay time and delay treatment. Therefore, shortening the time of serum separation is an urgent problem to be solved in the current inspection work. In this case, blood coagulant was born.

The main points of using EDTA-K2 as anticoagulant for blood collection tube EDTA-K2 refers to dipotassium ethylenediaminetetraacetic acid. It is an EDTA salt. It is commonly used as an anticoagulant in vacuum blood collection tubes. Due to its wide range of applications, the method of use in non-application is also different. Here Explain the main points of its use as an anticoagulant.
Experimental principle of agarose gel electrophoresis Agarose prefabricated gels are essentially similar to ordinary agarose gels, except that a large number of gels are prepared in advance and pre-stained with nucleic acid dyes in advance, eliminating the need for gel preparation time and nucleic acid electrophoresis. To purchase and use nucleic acid dyes, this article introduces the basic principles of agarose gel electrophoresis.
Desheng's report on how to control the growth of activated Virus Transport Media Recently, there are a lot of phenomena on the market that activated Virus Transport Medias grow bacteria during use. Many companies have returned goods. However, for Desheng, this problem does not exist. As for the problem of Virus Transport Media growth bacteria, we Asked Director Liu of Desheng Technology Department, he said that Desheng's activated Virus Transport Media does not grow bacteria.
Warmly congratulate Desheng Chemical on successfully completing the installation of new equipment The magpie climbed the branch to rejoice, and the breeze blew the Liumanman pear. On June 15, 2020, Desheng Biochemical completed the equipment installation work under the desperation of Desheng. In the early stage of the epidemic, Desheng organized all the staff to carry out the work of plant renovation and equipment upgrade. Increasing production capacity expansion is our starting point, but it is not our end. We hope to provide quality products to more customers while ensuring product quality.
Instructions for use of piperazine-1,4-diethylsulfonic acid PIPES Piperazine-1,4-diethylsulfonic acid PIPES, CAS No. 5625-37-6, is a widely used biochemical reagent, with a white powder appearance and weak acidity, usually dissolved in NAOH aqueous solution to make a biological buffer The buffer range is 6.1-7.5, suitable for neutral weak acid buffer system.
