 Zhongguang Wang Beijing June 30 news (reporters Du Ximeng), according to Voice of China "News" reported that summer, and in the evening,Xo32E21iVA, the food stalls, street vendors,u21vI5zYj5, roast the lamb skewers Ji Chuan, come bottles of beer, presumably a lot of people, in the summer to select a favorite leisure hot weather. Recently, however, Anhui University student Xue pure DNA is detected by way of Hefei 66 stalls made of chicken meat component testing, the results unexpectedly in 66 samples collected only about two percent of the lamb. Anhui University, 2009 graduate senior biology major Xue pure science is a animal lover, he feared that some unscrupulous merchants will kill stray animals to reduce the cost of kebabs. Xue pure: I am a member of our school Animal Protection Association, has been very concerned about the stray dogs and cats to protect this piece,louboutin soldes femme, because I saw a news report said that Guangdong has to catch stray cats and dogs used for mutton string,xgH1AUWc31, I wanted to see Kebab there are no such meat. I just want to graduate yet, just have such a good opportunity. After consultation and thesis advisor,nike air max 90, Xue pure decide the type of test in kebab meat as their thesis research. Xue pure: Then and our instructors talk about, that there are these stray cats chicken meat, not very likely, because of a moment that the meat supply is not very stable, does not have a sufficient supply of goods, and finally my The results also proved this point. The idea of a decision, Xue pure began the implementation process. He spent two months traveled four main city of Hefei, Hefei 66 stalls to buy back as 66 teriyaki chicken samples. Xue pure: Whether by bike or take a bus, ride a friend's car, then hit the stalls have to buy a bunch of lamb skewers. Then, beginning with the gene combination Xue pure variety of molecular biology tools in the DNA sample for testing, and finally compare global gene pool to confirm the type of meat. Xue pure: back we removed part of the meat, all kinds of processing of the DNA extracted, sequenced its look, and then generate the database than to look, you can determine what the meat. However, test results and teacher let Xue pure surprise, these kebabs in mutton content is less than two percent, filled with all kinds of poultry and pork and other varieties. Xue pure: test results in less than 20%, and only 19.7% are lamb, like pork accounted for 69% and other chicken, duck,tn reuqin pas cher,vD7z9HE1i5, beef as well as the emergence of the individual. Xue pure that such genetic testing technology is already very mature,SPYlPtMqyo, testing concluded that 100% accurate. Xue pure: Because whether human or animal, its DNA do not lie, who is who. 66 finish this experiment, really spent a lot of costs, but these are within the budget: Xue pure: with a different reagent, sample some of you may not be able to come out again,scarpe hogan online, probably if all down the total cost considerations,piumini woolrich,nu79Ckkvt6, a test should be meeting hundreds, this is our teacher-funded experiments we do, And we do undergraduate thesis schools are funded. Experimental data for one by the local media,wAcgoWUAgw, immediately aroused the concern of many people, Xue pure that he was just doing a small thing to do. Xue pure: to apply the knowledge I've learned, for the social progress it has made little contribution, pride really, can only say that I count it a clear conscience. After all, make some achievements, but also quite practical value. Now begin to focus on the general public from food safety issues, he is ready to make more efforts in the laboratory before the operation, and if the related business activities, must be recognized by the legal level. Xue pure: because this truly up and running, it will involve the issue of liability, if the results from the third party in the proceedings for recognition of words. I think the prospects for application up is very good. Xue pure representation, if you can obtain official authorization, the next step going to open a meat authenticity detection mechanism, so that people eat on safe meat. Xue pure: Meat genuine sources, we can do it. Beef and mutton hot pot use can be done. Anhui University Students by Xue pure DNA to detect kebab meat ingredient, then in the end how to check? Subtle molecular level how the gene than another? Reporters recently entered the Chinese Institute of Food and Drug test, food safety inspection techniques to explore this safety line the tongue. In the field of biological testing, DNA identification is the standard moves of a trick. Whether it is the storm before the uproar horse, or the current flurry of fake lamb event, it must determine using this technique. Dr. Chinese Academy of Food and Drug test, the current through the meat purified DNA sample amplification, essentially confirmed genuine lamb. Cuisheng Hui: Because normal DNA as software coding gene sequences we also ATCT sorted, usually using specific primers to amplify the lamb. Reporter: This is the equivalent of what the concept is to take a magnifying glass to put what thing? Cuisheng Hui: nor is he selected some specific sequence, for example, a sequence which has only sheep, pigs that period only, with this as a starting sequence to amplify, if it means something to spread out lamb through this It is not able to identify genuine and fake lamb. After this amplification and sample after re-entering the electrophoresis, because of the size of the different substances in specific molecular weight, arranged in a stripe pattern of high and low ranges, duck three times higher than the lamb, the results at a glance. Cuisheng Hui: for example, this is a genetic testing ducks emergence of this specific band, he showed that duck. Reporter: So this confirms the results of it? Cuisheng Hui: No, it's just 99 percent identified as duck, and ultimately we have to do genetic sequences required to International (DNA) database for comparison. Reporter: So you get your sample to the final result from how long it takes? Cuisheng Hui: the fastest, then, is about a week. Reporter: In fact, in front of the NDA detect it very quickly? Cuisheng Hui: day down. Cuisheng Hui frank,uSx2q320C0, although the results obtained have been basic day seems correct, but six days later, a 1% guarantee to get equally indispensable. Because 100% accurate test results in order to become certified food safety law enforcement force. Cuisheng Hui: Sometimes people will be very anxious, but this process is not to be shortened biological processes.
