Chapter nine hundred and ninety seventh shock
Yang Rui's voice made Wang Jiancheng feel inexplicably relieved.
If the scene was watched by more than 100 people, if it was a New Year's Day party, it might only be written as a sad story that was excluded. However, if it was a public experiment, the viewing of more than 100 people would be spectacular.
This is a biologist. He can barely get a person who strengthens the company and then change to a more uncommon subject. It will make people nervously tremble if they can come to thirty or fifty people - half of the world crosses the ocean to see me, it’s so sour.
Wang Jiancheng felt like he was doing an experiment in front of a biologist in half of Beijing and Beijing.
"Mouse No. 5..." Wang Jiancheng said while arresting the fifth mouse.
"Wait." Zhang Feng suddenly stood up and said, "Can I take a look at the two mice just now?"
Wang Jiancheng was at a loss and didn't know how to answer.
Yang Rui looked at Zhang Feng calmly, his voice was not loud, but he said clearly: "No."
"Huh? Why?" Zhang Feng didn't expect Yang Rui to reject him.
The scholars around him were surprised and talked.
Yang Rui signaled Wang Jiancheng to continue the inspection and asked Zhang Feng back: "Why do you want to see the two mice just now?"
"I..." Zhang Feng felt very confident and suddenly became less righteous. Yes, why did he look at those two mice? It was because he didn't believe in Wang Jiancheng, and because he didn't believe that Yang Rui's experiment would be successful.
However, such reasons are obviously not suitable for such a pride.
"When the examination is completed here, you will be given a chance, and the developing embryo will not disappear." Yang Rui tilted his mouth and turned to Wang Jiancheng, saying, "You don't have to be affected, just do your own thing with peace of mind."
"Okay." Wang Jiancheng was almost twice as old as Yang Rui, but at this time he regarded Yang Rui as a reliance.
"Mice No. 5, left cervix, uterine horn, one pair of half embryos..." Wang Jiancheng's voice reappeared, which also attracted everyone's attention again.
"Is it active?" An anxious scholar asked in a whine.
In some people's eyes, this may be an interesting live show.
Although frozen embryo transfer is an important genetics topic, if it doesn’t matter, your mentality will be different.
In contrast, scholars like Wang Jiancheng or Zhang Feng are not so free and easy.
Zhang Feng even followed the source of the sound and glanced back with dissatisfaction.
Wang Jiancheng coughed and said in a low voice: "Well, the half embryo on the left...is active."
Zhang Feng, who was looking back, was stunned and suddenly turned around and looked at Wang Jiancheng with suspicion in his eyes.
"The third one is only active?"
"You've read it wrong."
"What's going on?"
The scholars around him have completely lost their concepts.
Among the five mice in total, three of them are active, which is no longer explained by the fate of the great fortune.
Even in many laboratories nowadays, even ordinary embryo segmentation and transplantation techniques do not necessarily have such a chance of success.
Including Academician Wu Hongbo, he couldn't help but look at Yang Rui.
There was no expression on Yang Rui's face.
Although he chose a relatively backward plan when designing the experimental plan, in order to increase the success rate, the technology used in the plan was relatively mature. Therefore, the situation in front of him was originally as expected.
In fact, in Yang Rui's opinion, the three of the five mice are only active, and there is not a high probability.
You should know that two pairs of half embryos were transplanted into each mouse. In other words, there were 4 half embryos in each mouse, and five mice had a total of 20 half embryos. So far, only 3 half embryos were active in total, with a success rate of only 15%!. (MISSING)
If such a success rate is used for commercialization, it will lose the bottoms.
Of course, embryo transfer in cattle is different from embryo transfer in mice. At least four half embryos will not be transplanted in one breath.
However, Yang Rui didn't find strange results. In China in 1985, it was a very advanced result.
Embryo transfer technology was carried out in the 1970s. According to normal technological diffusion, by 1985, embryo transfer is still a new technology for scholars in third world countries. Compared with countries of the same level, such as Egypt, India, and Turkey, China started a little later in related scientific research. Because China was basically closed to the country in the 1970s, foreign technical information was basically not available. In other words, domestic scholars can still learn some paper or theoretically based on international research in the 1960s, but they are not prepared for the technology that appeared in the 1970s.
The country's door suddenly opened, and the embryo transfer technology, which was at its peak, suddenly blinded the eyes of Chinese genetic researchers. At this time, they started research in a hurry. In terms of learning efficiency, they may be worse than those of graduate students studying abroad.
A 15% success rate is not as weak as the best score in China, but it is very strong if compared with the average score.
It can be said that there are only a handful of scholars present who can achieve a success rate of 15% in embryo transfer.
This polarization is like the gap between the rich and the poor, and it is the gap between the rich and the rich who cannot imagine the wealth.
For a time, many people cast doubtful eyes.
Fortunately, with the previous endorsement from Academician Wu Hongbo, the scene will not be in chaos.
However, the messy voices were chaotic enough.
This time, Wang Jiancheng was not affected anymore and silently continued his inspection work.
"Mice No. 6, right side of the uterus, uterine horn, a pair of half embryos... are active."
"Mice No. 8, left cervix, uterine horn, one pair of half embryos... are active."
"Mice No. 9, right side of the uterus, uterine horn, a pair of half embryos... are active."
"The mouse number 10, right side of the uterus, uterine horn, a pair of half embryos... is active."
Wang Jiancheng's voice was always accompanied by the noisy sounds in the room.
However, the noise is getting smaller and smaller.
Finally, a total of 10 active half-embryos were detected in 15 mice, with a success rate of 16.7%, a not surprising and shocking number.
Scholars in the laboratory, including Gu Qiang and Ouyang Shi, who participated in the experiment, also fell into silence for a long time.
"Will something go wrong?" Someone couldn't help but mutter.
Immediately, someone echoed: "I also think that these mice would not mate on their own."
This time, Yang Rui was no longer polite. Without waiting for more people to speak, he stood on the stool and looked down at the crowd, saying, "This experiment is the opening work of my newly established Haidian District Genetic Engineering Laboratory. I am willing to accept your supervision - but!"
Yang Rui bit the voice very hard, looked at everyone, and said, "But if someone wants to accuse me of falsification of experiments or other academic misconduct, please provide evidence, otherwise, I will fight you to the end of this lawsuit."
All the scholars who just said the slutty words were silent.
It is extremely serious accusation when pointing at a scholar who commits fraud. It is okay to chat in private, but if you take it seriously, it will attract the case that the Commission for Discipline Inspection has intervened. In terms of Yang Rui's fame, it is an international incident. No one dares to be happy and just criticize him wantonly.
However, a famous middle peasant professor turned around and said, "Director Yang, why not announce your experimental design so that everyone can consider it."
"I will announce it when necessary." Yang Rui glanced at the vice president of China National Animal Husbandry Corporation and said with a serious expression: "After the Haidian District Genetic Engineering Laboratory is officially established, we will further conduct related research. At that time, everyone should get more information."
