"We can do a test." Standing among a group of Stockholm police, Yang Rui said in English: "you can provide me with a head, and then select several people for us to test. At this time tomorrow, I will tell you who the head belongs to."

As an interpreter of the embassy, Deng stood beside Yang Rui and translated his English into Swedish to avoid misunderstanding.

On the other hand, the pride of Swedes is obvious. They always prefer Swedish to English, German or French, even if they understand it.

Yang Rui asked Huang Mao to take pneta. This machine is called a pneta strand. We can expand it endlessly without even a DNA strand, a part of DNA strand. "

Seeing that the crowd was confused, Yang Rui immediately changed the mode and said, "in short, the minimum requirement of a PCR instrument is a cell. Therefore, its advantages are very obvious. Any slight mistake made by a criminal at the scene of a crime may become our clue. "

"Do you put these hairs and cells under a high magnification microscope?" A policeman raised his voice and asked, if he knew the word multiple, it showed that he knew something about the experiment.

"The principle of PCR is slightly different from that of microscope, but what we get in the end is indeed an image, which can also be understood in this way," said Yang Rui

His explanation was obviously flawed. Huang Mao said in Chinese: "director Yang, it's not like a microscope."

"I don't say it's similar to a microscope. I mean it's slightly different from a microscope. What we end up with is an image, right?" Yang Rui seriously corrected Huang Mao.

Huang Mao Leng Leng, said: "the PCR instrument and microscope are not only slightly different."

"From a layman's point of view, a slightly different description is enough." Yang Rui stopped speaking Chinese and continued to say in English: "I'm sorry, my assistant wanted to tell you more detailed and clear principles. I rejected it. I think we should master the method of collecting evidence well. It's better to assign a special person to be responsible for the use of the PCR instrument, so as not to lose money in court."

When Yang Rui said this, the director thought it was true, and said, "that's right. We should abide by the rules and do everything according to the book. In addition, the collection of evidence and evidence collection should also be based on the manual provided by Mr. Yang Rui. "

Huarui laboratory has long prepared the code of practice for the use of PCR, especially the sampling criteria, and tried to promote it in Hong Kong and other police stations. Yang Rui knows that there is no need to translate it. He can just take the English version directly.

Some of the police nodded, some were still unconvinced and yelled: "even if you use this PCR, why do you have to hire this company?"

The other side uses Swedish. When Deng translated it to Yang Rui, he continued: "is this unique technology? Unique technology from China, how can we solve the case? I dare not present such evidence to the court, and the judge will not pass it as evidence. "

"Picker." Sherwood, the director, stood up, looked at the officer who was talking, and said, "you'd better put that away and do your own thing well."

His words were harsh, his eyes turned, and he was humane to the public: "the case of Muller has now received special attention from all parties. What we have to do now is to determine the suspect first, and then decide how to prosecute. If necessary, I believe Mr. Yang Rui can explain clearly to the judge what a PCR instrument is. If not, it's a stupid judge's decision, not us deciding whether to believe in a new technology - we're going to use all the technology, OK? It's not like a German who criticizes any new technology first“

His discrimination against the Germans caused a burst of laughter.

"Since we know we have to explain to the court, why don't we get a Swedish professor to operate these machines," picker said

Listening to the synchronous translation, Yang Rui said quickly, "because we can provide a better PCR instrument."

"Better PCR? Is it better than Sweden? " Pikel asked with a smile.

Yang Rui did not answer this question directly, but said euphemistically: "I know the PCR instrument, and the patent period is not over, so now I sell all the PCRs in the world. What I'm bringing out now is the second generation of PCR instrument that has not yet been put on the market. It's smaller, more portable and faster. All these are the functions you need. "

No need for him to make it clear. We all understand what Yang Rui means. All the world's PCR instruments come from me. This one is not for sale.

In fact, what Yang Rui brings out now is not the real second-generation PCR, but if he wants to be called the second-generation, other people have no way.

Without waiting for picker to speak, Sherwood first stood up and said, "this is the end of the discussion. Let's do an experiment to verify the function of the PCR instrument. At the same time, we need to prepare for the clues that will be exposed next..."Sherwood directly arranged the work. Yang Rui motioned to Huang Mao twice and then started to operate.

pcR In fact, the instrument is very simple to use. To get rid of the tedious steps, it can be summarized as follows: turn on the machine, insert the raw materials, and get the conclusion.

If you are proficient in these three steps, the number of experiments you can carry out in one day is considerable.

In the future scientific research laboratories, some postgraduates have studied for three years. For two years, they have been running PCR, running behind. They are as fast as bolt in the laboratory. They only need a few seconds to have a relationship with a group of DNA students.

Huang Mao was also a leader in Huarui laboratory after Yang Rui dug him up from Peking University. After several years of cultivation, his calf temperament has been at its peak with a huge amount of resources. Without Yang Rui's help, he has put the machine into operation.

Tu Xian took a cotton swab and began to take the epithelial tissue of the police uncles and aunts. That is to tamp the small cotton swab in the gingival position, and smear the cotton swab with the natural shedding cell tissue of the human body.

In addition to all kinds of time-consuming operation, it only took more than ten minutes for the PCR instrument to get rid of people completely, which is similar to the difficulty of operating the microwave oven.

Yang Rui saw that it was basically finished, and said, "at this time tomorrow, we will see the results. We will have people here for consultation."

Yang Rui didn't stay directly. He thought it might be better to communicate.

A group of police looked at the beep like a PCR instrument boiling water. They always felt that the sense of high technology was not enough. Some people doubted and asked, "is this OK?"

What he means is that it's not the science fiction show in the movie.

Yang Rui shrugged and said, "that's OK. We've added seals and locks to the machine. We'll reveal it tomorrow. Believe me, this will be the most useful machine you've ever used."

"More useful than a coffee machine?"

"Well, second only to the coffee machine." Yang Rui makes a joke with him. It's rare that Swedes are willing to make a joke.
