Hong Beijing June 30 news (reporter Duxi Meng), according to Voice of China "News" reported that summer, and in the evening, the food stalls, street vendors, grilled lamb skewers on several strings, come back bottles of beer, presumably a lot of people, in the summer to select a favorite hot weather leisure. Recently,OQV3BJ2u9Q, however,mulberry outlet, Xue pure Anhui University student, by way of DNA to detect, Hefei 66 stalls were skewers of meat ingredients, and the results unexpectedly in 66 samples collected in the lamb only about two percent.
Anhui University 2009 Professional senior biological science graduates is an animal lover Xue pure, he feared some unscrupulous businesses 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, because I saw news reports that Guangdong has to catch stray cats and dogs used for lamb skewers, 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, Xue pure determines the type of test where kebab meat as their thesis research.
Xue pure: Then and our instructors talk about, that there are these stray cats chicken meat,a6XTSC6sDy, the likelihood is not great, because of a moment that the meat supply is not very stable,hQAlJ1DWJ1, does not have a sufficient supply of goods,tn requin pas cher, and finally my The results also proved this point.
The idea of ??a decision, Xue pure began the process of implementation. He spent two months time,KsHSl3r3WT,nike air max pas cher, traveled to four main city of Hefei, Hefei 66 from 66 skewers kebab stalls to buy back as samples.
Xue pure: Whether riding a bike or take a bus, take a friend's car, then hit a string mutton stalls to buy a bunch.
Then,fRF1vOzheN, beginning with the gene combination Xue pure biological means of various molecules in the DNA sample for testing, and finally confirm the type of comparative global gene pool of meat.
Xue pure: back,chaussures nike pas cher, we remove the part of the meat, all kinds of processing the DNA is extracted,moncler outlet online, its sequence determined look on the database and then generate alignments look, you can determine what meat.
However,HS71yo40V7, test results and teacher let Xue pure surprise, these kebabs,Eo2w88D8y0, the content is less than two percent of lamb, pork, chicken and duck filled with all kinds of other varieties.
Xue pure: test results in less than 20%, and only 19.7% are lamb, like pork accounted for 69%, the other chicken, duck, beef as well as the emergence of the individual.
Xue pure that such genetic testing technology is already very mature, testing and concluded that 100% accurate.
Xue pure: Because whether human or animal, it's DNA do not lie,peuterey outlet milano, and who is who.
Experiments done this 66 times, really spent a lot of costs, but these are within your budget:
Xue pure: with the different reagents, sample some of you may not be able to come out again, probably if the total cost of all considerations down, a test should be at the one hundred, this is our teacher-funded experiments we do, And we do undergraduate thesis schools are funded.
Experimental data one by the local media release, immediately aroused the concern of many people, Xue pure said he just did a little thing to do.
Xue pure: the use of the knowledge I have learned,moncler milano, for the progress of society to make a little contribution to it, really proud of, can only say that I count it a clear conscience. After all,moncler outlet, has also made some achievements, but also quite practical value.
Now the general public began to show concern for food safety issues, he is ready to make more efforts in the laboratory before the operation, and if the related activities of commercial, legal aspects must be recognized.
Xue pure: Because this truly up and running, it will relate to legal liability issues, if the results of third-party recognition in legal proceedings words. I think it's still a good prospect of application.
Xue pure that if you can get official authorization, the next step going to open a mechanism to detect the authenticity of meat, so that people eat on safe meat.
Xue pure: Meat genuine sources, we can do it. Beef and mutton hot pot can be used to do.
Anhui University Students Xue pure by DNA to detect kebab meat ingredients, then in the end how to check? Subtle to the molecular level how the gene than another? This reporter recently walked into the Chinese Institute of Food and Drug verification, food safety inspection techniques to explore this safety line on the tongue.
In the field of biological testing, DNA identification is a standard trick clincher. Whether it is the storm before the hubbub of the horse, or the current flurry of fake lamb event,peuterey prezzi, it is necessary determination using this technique. Dr. Chinese Academy of Food and Drug  verification, the current through the meat amplification of purified DNA samples can basically confirm genuine lamb.
Cui Shenghui: Because normal DNA as software coding gene sequences we also ATCT sorted, so 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?
Cui Shenghui: nor is he selected some specific sequence,giubbotti woolrich, such that there is a sequence only sheep, pigs that period only to this as the start sequence to amplify, if something comes out that is expanding lamb, through this is not able to identify genuine and fake mutton.
The amplified samples after and after re-entering the electrophoresis apparatus, because of the size of the different substances in specific molecular weight, high and low ranges lined ribbon graphics,IaDvF3IbV9, duck three times higher than the lamb, the results at a glance.
Cui Shenghui: for example, which is a genetic testing ducks emergence of this specific band, he showed duck.
Reporter: So this confirms the results of it?
Cui Shenghui: No,nike air max pas cher, this is only 99% identified as duck, and ultimately we need to do gene sequence requires international (DNA) database for comparison.
Reporter: What got you out of the sample to the final result of how long it takes?
Cuisheng Hui: The fastest, then, is about a week.
Reporter: It is actually in front of the NDA detect very fast,woolrich outlet?
Cui Shenghui: one day down.
Cui Shenghui frank, although the results seem to get the day has been basically correct, but six days later, get 1% guarantee the same indispensable. Because 100% accurate test results in order to become certified in food safety enforcement forces.
Cui Shenghui: Sometimes people will be very anxious, but this process is not to shorten biological processes.
