Henan successful production of influenza detection kit (Map) - Influenza - pharmaceutical industries

"Two hours! Just two hours, you can quickly test to determine whether patients infected with the influenza A H1N1 virus !"??( 6 pm) 4 pm, the reporter in Henan Engineering Research Center for Bio Molecular biological experiments room, see the Biotechnology Research Center of Henan Province, chief expert Wang Yunlong, his first move was good news out of two fingers!

5 11 at midnight, when reporters contact Wang Yunlong, the research team has battled hard with 10 days of the provincial research center leader biological test given in the latest standard operating hours or 3 hours, more rapid test kit is being tested, verification.

HC Pharmacy Industrial network with map

Less than 20 hours after continued efforts, Wang Yunlong team has broken one after another the other departments announced on May 3 to 5 hours to complete the pigs infected with influenza A H1N1 virus detection limit, minimum two hours to the results of a nationwide R & D-type H1N1 virus detection reagent "emergency in the Race", by running in the forefront.

6 pm when reporters on the scene were in the molecular biology laboratory, reagent preparation laboratory, and genetic engineering labs, see the center of molecular diagnostics expert Dr. Li Zhitao, Li Yulin, director of genetic engineering specialists, immunization diagnosis expert Susan Branch Professor and Dr. Liu Wanggen and other research team members are methodically working tension.

"If necessary, these reagents by a suitable means to free the quickest way to send to all levels of the new cities and counties in Henan Province Influenza Designated hospitals or designated health prevention and control institutions "?? Wang Yunlong answering questions from reporters, said.

5 7,'s telephone interview with Zhang, deputy director of Science and Technology Department of Henan Province on behalf of the people, asked his assessment of the results of the study, he said: "The very recognition! We should be prepared for." Reporter learned The Center is carrying out the advantage of rapid diagnosis of one of the units in the first study in China during the SARS SARS success of the first rapid diagnostic reagents and known access to national drug certification. Initially in the "swine flu" disease began before the release of the April 23, the center is sensitive to the team, has started to actively find related information do a lot of preparatory work.

2009 4 28 United States on public alpha (H1N1) influenza virus gene sequences, the central research team night analysis, design, multiple pairs of primers were optimized for three pairs of specific primers were synthesized good, after days and nights continuous research, experiment, verify, May 4 kit for success.

Wang Yunlong, said test kit for the successful development of efficient, thanks to the provincial party committee provincial government, the Zhengzhou municipal government attach great importance. Science and technology in our province and Zhengzhou city government department in charge of rapid response carefully arranged, the first time to support biotechnology research center in Henan Province of human infection with swine influenza start Epidemic Prevention and control strategies and key technology research, careful organization and scientific research early and rapid diagnostic reagents, the Provincial Science and Technology Department Director Zhao Chen, deputy director and director of special appointed Director of Social Development Centre in person to understand biological research and progress, to see scientists. Zhengzhou City Science and Technology Secretary Wang Jichang two research groups reported on the deployment of special arrangements to listen to related work, and to arrange and social development, Deputy Secretary in charge Director of the first line in person, on-site to solve some research on the problems encountered. Research team worked day and night through the research and experiments have been used center technology platform for rapid diagnosis of diseases and in molecular biology, molecular hybridization, gene amplification and other aspects of the advantages of accumulated technology, successfully developed such a rapid, specific, sensitive Influenza A (H1N1) influenza virus detection kit.

The reagent has three distinctive features :

An advanced technology. The design of the project has the following six technical advantages: the use of advanced triple PCR technique; using one-step rapid test; by UNG pollution prevention system; using component separation and release, to ensure high specificity; used throughout every step of the internal control system detects reaction; with nucleoprotein NP, neuraminidase (NA), hemagglutinin (HA) 3 gene in multiple confirmed to detect were more detailed understanding of the characteristics of the sample.

2, speed, and can be detected within 2 hours. Provincial Life Centre with high efficiency, sophisticated nucleic acid extraction technology that can be completed in half an hour fast, high-yield target template extraction process, compared with the traditional method to triple its output, while in the process of triple PCR amplification technology to operate double time and effort to reduce 2 / 3.

3, results are reliable. The project uses the amplified fragments of different sizes of three pairs of primers, PCR technology using triple swine influenza A (H1N1) genes were detected, while adding a whole system of reference to track, because the operator can avoid a result of incorrect operation miscarriage of justice or the kit itself, the result of problems caused by false positives, and can ensure sensitivity of detection.

The purpose of the project using a simple and quick detection method for qualitative strip test, has wide adaptability. Equipment only general PCR, can be early and rapid diagnosis, with the maneuverability is strong, using the broad features. In the current "swine flu" continues to spread the grim situation, in time, rapid diagnosis is extremely important. Currently, the successful development of the project, is actively involved in science and technology of Henan Province "swine flu" prevention and control of action and important stage, we will have far-reaching in Henan Province's social health impact.

High Quality Content by WIKIPEDIA articles A reagent is a substance or compound that is added to a system in order to bring about a chemical reaction or is added to see if a reaction occurs . Such a reaction is used to confirm the presence of another substance. Examples of such analytical reagents include Fehlings reagent, Millons reagent and Tollens reagent. Although the terms reactant and reagent are often used interchangeably, a reactant is more specifically a substance that is consumed in the course of a chemical reaction. Solvents and catalysts, although they are involved in the reaction, are usually not referred to as reactants. In organic chemistry, reagents are compounds or mixtures, usually composed of inorganic or small organic molecules, that are used to affect a transformation on an organic substrate. Examples of organic reagents include the Collins reagent, Fentons reagent, and Grignard reagent. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Tollens Reagent


Tollens Reagent


$79.66


High Quality Content by WIKIPEDIA articles Tollens reagent is usually ammoniacal silver nitrate, but can also be other compounds, as long as there is an aqueous diamminesilver(I) complex. It was named after Bernhard Tollens.The diamminesilver(I) complex is an oxidizing agent, which is itself reduced to silver metal, which in a clean glass reaction vessel forms a silver mirror : Ag(NH3)2]+ (aq) + e Ag (s) + 2 NH3 (aq) This feature is used as a test for aldehydes, which are oxidized to carboxylic acids. It should be noted that the actual oxidation product is the carboxylate ion, which on acidification gives the corresponding carboxylic acid. Once it has been identified that there is a carbonyl group on the organic molecule using 2,4dinitrophenylhydrazine (also known as Bradys reagent or 2,4DNPH), Tollens reagent can be used to ascertain whether the compound is a ketone or an aldehyde. Importantly, there is a special case in which Tollens Reagent will give a positive for a ketone. If the ketone is an alphahydroxy ketone, then the Tollens reagent will react.

High Quality Content by WIKIPEDIA articles Collins reagent is the complex of chromium(VI) oxide with pyridine in dichloromethane. It is used to selectively oxidize primary alcohols to the aldehyde, and will tolerate many other functional groups within the molecule. It can be used as an alternative to the Jones reagent and pyridinium chlorochromate (PCC) when oxidising secondary alcohols to ketones. Moreover, the Collins reagent is especially useful for oxidations of acid sensitive compounds.This complex is both difficult and dangerous to prepare, as it is very hygroscopic and can inflame during preparation. It is typically used in a sixfold excess in order to complete the reaction. Nowadays, PCC or PDC oxidation have largely supplanted Collins oxidation for these very reasons.

High Quality Content by WIKIPEDIA articles Nesslers reagent is a reagent named after Julius Nessler and is used to detect small amounts of ammonium ions.. It is a 0.09 mol/L solution of potassium tetraiodomercurate(II) (K2 HgI4]) in 2.5 mol/L potassium hydroxide. A yellow coloration indicates the presence of ammonia: at higher concentrations, a brown precipitate may form. The sensitivity as a spot test is about 0.3 g NH3 in 2 L. It is toxic if swallowed, inhaled or absorbed through the skin. It presents a neurological hazard and may act as a carcinogen and be a reproductive hazard. It is corrosive and causes burns. Nesslers reagent is generally prepared from potassium iodide and mercury(II) iodide. A hot concentrated solution of mercury(II) chloride is added to concentrated solution of potassium iodide, until the precipitate of mercury(II) iodide stops dissolving. The liquid is filtered, and potassium hydroxide and a further bit of mercury(II) chloride solution are added. The resulting solution is then cooled and diluted to required concentration. Nesslers reagent may be used with Nessler tube Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.
