With the participation of Professor Ouyang Shi, the experimental progress of frozen embryo transfer has inexplicably accelerated.

Gu Qiang's operation speed was already quite fast, but it was more agile at this time.

Maybe I don't want to let the road be too far.

Yang Rui guessed Ma’s thoughts.

In the laboratory, the most natural period of silence was also entered, with only the jingling sound of moving metal, as well as short and powerful conversations.

This is the norm in the laboratory. Everyone felt the familiar atmosphere and felt comfortable.

After a long time, Gu Qiang stretched and said, "Most of the half embryos have been processed, can you catch up?"

"The time is almost the same, let's thaw synchronously." Yang Rui replied, turning to other scholars and explained: "Our experiment today is to prove that the segmentation of frozen embryos can be used for embryo transfer, and the duration of freezing is not examined. In order to save everyone's time, we will now start thawing the embryos that have just been frozen. Wang Lei and prepare the balance solution."

Wang Lei, who was responsible for being an assistant, immediately became busy.

This is also the time when scientific research Wang can play a big role. The configuration of processes such as balance fluid also requires fine operations. If there is no suitable experimental assistant, Gu Qiang can only do it himself, and the progress will be more than twice as slow.

The frozen half embryo is immediately thawed, which is theoretically no difference from thawing after a period of time.

Using this method is enough to prove whether frozen embryo transfer has been successful.

The lab became busy again.

Zhang Feng was even more disliked and couldn't help but speak, "You guys are so funny. With so many key steps, why don't you do it separately?"

Embryo segmentation, embryo freezing, embryo thawing and embryo transfer can all be regarded as different experimental steps, and his problems are very real.

However, Yang Rui did not regard frozen embryo transfer as such a huge project. Not to mention that this was a problem that foreign biologists in the 1970s had solved. When Yang Rui was studying for a graduate school, he would repeat such an experiment in any ragged laboratory? He could even use the graduation thesis for master students in genetics. How could this make Yang Rui have the idea of ​​being cautious and step by step?

Wasting time is wasting life. Yang Rui said without looking back: "Look at the result. If it cannot succeed, we will reverse the steps."

"I want to see the results." Zhang Feng didn't believe Yang Rui at all.

Ouyang Shi heard this obvious distrust. He shouted, turned his head, stared at Zhang Feng's eyes for a while, and said, "Professor Zhang, you are not allowed to think like this. I doubt whether you have basic judgment ability."

"My judgment ability? What's wrong with my judgment ability?"

Ouyang Shi said twice and said, "This is Mr. Yang Rui's project, how could it be unsuccessful? If you don't even have such a judgment... I suggest that you learn from Comrade Gu Qiang and get a divorce. Without the burden of the family, your judgment ability is expected to gradually recover."

Zhang Feng's face was flushed. Who did not have the ability to judge?

Gu Qiang was even more angry and said anxiously: "I'm not divorced for work!"

Ouyang Shi asked back: "What is that for?"

Gu Qiang's mind was blank for five seconds and he slowly said: "For science."

"Well said!" Ouyang Shijiji praised, saying, "You said so much that I was so excited. If I hadn't beat my wife, I would have divorced."

...

The experiment of frozen embryo transfer was completed on the third day and was considered to have a clear idea.

After announcing the transplant the next day, Yang Rui returned home and slept with a solid sleep.

The next day.

Yang Rui was a little later and rode his bicycle to the Peking University Ion Channel Laboratory.

Before I reached the place, I saw shadows of people.

Yang Rui couldn't help frowning.

When I arrived at the entrance of the ion channel laboratory, there were at least fifty or sixty people gathered here, so that the originally empty road was blocked by most of the students passing by had to pass by carefully passing by the corners, leaving a look of awe.

Just a famous and surnamed Peking University professor was present! There were as many as seven or eight people.

Yang Rui didn't dare to take the big shots, so he got out of the car and pushed him over from a distance, and then greeted him one by one: Professor Fang, Professor Li, Professor Zhang, Professor Qian...

When we arrived at the gate, the familiar backs of Professor Cai and Dean Liu also appeared.

Needless to say, the people who are watching the experiment results are all looking at the results.

Yang Rui was a little helpless, but also a little secretly happy. When he was doing research on potassium ion channels, how many people in the world believed he could do it? Except for colleagues in the laboratory, it can basically be said that there was no one.

What about now?

Yes, everyone is still not optimistic about the frozen embryo transfer he did, but even if it fails, everyone will still watch.

Not to mention academic failures, it still has unusual value. It is actually beyond the current academic level to transfer frozen embryos and advance them to the transplantation stage.

If Yang Rui adopts a phased experimental method, he will not only win a big victory now, but at least he can declare some victory and then recruit funds.

In front, Professor Cai also saw Yang Rui, greeted him, and said, "Committee Wu Hongbo is coming too, let's stand and wait."

"Ah... why is he here?" Wu Hongbo is also an academician of Professor Cai's family, but he will not come to Peking University at any time. Compared to Yang Rui, scholars with the title of a member of the school department can be more than three times more busy.

Professor Cai laughed twice, looked at Yang Rui with a funny look, and said, "Commissioner Wu, he is from the Institute of Genetics of the Chinese Academy of Sciences."

Yang Rui slapped his forehead and said, "I'm so busy."

"Don't let him poach the person." Professor Cai whispered again.

"Yes, you think comprehensively." Yang Rui really admired. Those who can think of this level probably have done such a thing.

After a while, Academician Wu Hongbo arrived, and several other scholars in their forties and fifties were followed by.

Without introducing, Yang Rui recognized two of them.

He has read many genetic engineering journals recently, and scholars with names are also bound to have to hang their avatars into journals.

So many people greeted each other, and they were panicked again. After they figured it out, they were invited to enter and there was no more in half an hour.

Yang Rui sighed secretly and had to thank everyone for coming. This is true. If he had not been successful in his face, there would not be any good things that all the wise men would have come here now.

Of course, success in the experiment is a good thing, but failure in the experiment may not be necessary.

This is also the reason why Yang Rui did not make a big announcement. However, he wanted to put satellites in public and control the scale. However, Yang Rui could not control such a good thing.

Fortunately, Gu Qiang and Ouyang Shi were calm in front of the laboratory bench. They were people who had seen big scenes and were not scared by about a hundred people.

In contrast, Wang Jiancheng, a veterinarian invited from the Veterinary Research Institute of China Animal Husbandry Corporation, was a little nervous.

In order to prove that the operation difficulty of embryo transfer has reached the commodity-level requirements, of course, this premise is that embryo segmentation, culture, preservation and other technologies are all completed by the genetic engineering laboratory.

However, for China Animal Husbandry Corporation, as long as the goal can be achieved, they don’t care how it is accomplished.

"Doctor Wang, please do general anesthesia on the recipient mouse first." Yang Rui asked Wang Jiancheng to do the previous steps first. Even if something goes wrong, just change the set, and it will not affect the final success rate.

Wang Jiancheng was stunned for a moment, quickly agreed, and removed sodium isoprenebarbital from the test stand and absorbed it quantitatively...

In the veterinary research institute of China Animal Husbandry Corporation, Wang Jiancheng actually often does scientific research, which is why Yang Rui chose him. However, Wang Jiancheng has been doing scientific research for his whole life, and has never operated under the gaze of two academicians and dozens of well-known scholars. He couldn't help but feel a little stiff all over.

Fortunately, the requirements for his operation are not high, and the mouse’s husband will not make trouble because of his injection method.

After a while, all the recipient mice gathered in place.

Yang Rui immediately ordered, "The incision of the midline of the abdomen exposes both the uterus and the uterine horns."

This part is also Wang Jiancheng's operation.

Immediately afterwards, Gu Qiang took over and moved into the half embryo with Wang Jiancheng.

Complete the experiment in groups.

The process is a bit dull, but the atmosphere is always difficult to relieve tension.

By noon, everything was announced to be over, and Yang Rui also breathed a sigh of relief and said, "In the afternoon, the proportion of live feces can be determined."

The quiet environment in the laboratory was wiped out, and the famous scholars immediately threw out the words they had saved in their stomachs for a long time, but the content was not supported by Yang Rui.

"It's unlikely that there will be a live fetus."

“Where could it be that simple.”

"Even if there is no live fetus, this experiment is worth referring to."

"If there is no live fetus, it should be pushed back. In my opinion, Yang Rui's experimental conditions are not enough."

"It's a bit too fast to do embryo segmentation and frozen embryos at the same time. At that time, it's not clear whether there is any problem."

"This makes sense. There are not many laboratories that can do embryo segmentation now, and then frozen embryos are put on..."

Although Gu Qiang is an experimental operator, he is actually not optimistic about Yang Rui's experimental design and has no confidence in the results.

However, Gu Qiang couldn't help but mutter: at least one living, at least one living...

As a direct operator of the experiment, as long as one mouse survives, he can gain more fame than before.
