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

Gu Qiang's operation speed was originally quite fast, but at this time he was even more agile.

I guess I don't want to get too far away.

Yang Rui guessed Ma's thoughts.

In the laboratory, too, there was a period of natural silence, with only the sound of tinkling moving metal and short but powerful conversations.

This is the norm in the laboratory, and everyone feels the familiar atmosphere and feels comfortable.

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

It's about the same time, let's thaw it synchronously. Yang Rui replied, turned his head and explained to other scholars: Our experiment today, as long as it is to prove that the embryos after segmentation and freezing can be used for embryo transfer, regardless of the freezing time, in order to save everyone's time, we will now start to thaw the embryos that have just been frozen. Wang Lei, prepare the balance solution.

Wang Lei, who was in charge of acting as an assistant, immediately got busy.

At this time, it is also the time when scientific research Wang can play a big role, and the process of configuring the balance liquid and other processes also requires fine operations, if there is no suitable experimental assistant, it can only be done by Gu Qiang himself, and the progress will be more than twice as slow.

The half embryo is thawed immediately after freezing, and there is theoretically no difference between thawing after a period of time.

In this way, it is enough to prove that the frozen embryo transfer is successful.

The lab is busy again.

Zhang Feng looked even more unpleasant, and couldn't help but open his mouth and said: You guys are too child's play, so many key steps, why don't you do them separately

Embryo segmentation, embryo freezing, embryo thawing and embryo transfer can all be regarded as different experimental procedures, and his problem is very real.

It's just that Yang Rui didn't regard frozen embryo transfer as such a huge project, not to mention that this was a problem that foreign biologists in the 70s had solved.

Wasting time is a waste of life, Yang Rui didn't look back and said: Look at the results, if it can't be successful, let's go backwards.

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

Ouyang Shi heard this obvious distrust, he snorted, turned his head, stared at Zhang Feng's eyes for a while, and said, "Professor Zhang, you don't want to think like this, I doubt that you have basic judgment ability.

What's wrong with my judgment

Ouyang Shi sighed twice and said: This is Mr. Yang Rui's project, how can it not be successful If you don't even have such a judgment I suggest, you can also learn from Comrade Gu Qiang, divorce. Without the burden of family, your judgment can be expected to gradually recover.

Zhang Fengqi's face was flushed, who was the one who had no ability to judge

Gu Qiang was even more angry, and said urgently: My divorce is not for work

Ouyang Shi asked rhetorically: What is that for?

Gu Qiang's brain went blank for five seconds, and he said slowly: For science.

Ouyang Shiji praised it well, and said: What you said, I am excited, if I didn't beat my wife, I would have divorced.

The experiment of frozen embryo transfer was completed on the third day, which can be regarded as an eyebrow.

After announcing the transplant the next day, Yang Rui returned home and slept soundly.

Following.

Yang Rui came to the Ion Channel Laboratory of Peking University on a bicycle a little later.

Before I got to the place, I saw a shadowy figure.

Yang Rui couldn't help frowning.

When I arrived at the door of the ion channel laboratory, sure enough, there were at least fifty or sixty people, crowded here, so that most of the originally empty road was blocked, and the students passing by had to pass by cautiously passing by, leaving a look full of awe.

Just the professors of Peking University who have names and surnames, there are as many as seven or eight people present.

Yang Rui didn't dare to take it big, so he got out of the car and pushed it over, and then greeted them one by one: Professor Fang, Professor Li, Professor Zhang, Professor Qian

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

Needless to say, the people who eat melons in front of them are all here to see the results of the experiment.

Yang Rui was a little helpless, but also a little dark, thinking that at the beginning, when he was doing research on potassium ion channels, there were several people in the world who believed that he could make it, except for colleagues in the laboratory, it can basically be said that there is none.

What now

That's right, everyone is still not optimistic about the frozen embryo transfer he did, but even if it fails, everyone will have to watch.

Not to mention academic failures, it still has unusual value, and being able to advance frozen embryo transfer to the transfer stage is actually beyond the existing academic level.

If Yang Rui adopts a phased experimental method, he can at least announce a partial victory if he doesn't win a big victory now, and then solicit funds.

Ahead, Professor Cai also saw Yang Rui, said hello, and said, "Commissioner Wu Hongbo is also coming, let's stand and wait."

Ah, how did he come. Wu Hongbo also belongs to the academician of Professor Cai's department, but he will not come to Peking University in his spare time, compared to Yang Rui, a scholar with the title of a member of the department can be more than three times busy.

Professor Cai laughed twice, looked at Yang Rui with a funny look, and said: "Member Wu, it's from the Institute of Genetics of the Chinese Academy of Sciences."

Yang Rui slapped his forehead and said: I'm busy fainting.

Don't let him poach people. Professor Cai whispered again.

Yes, you think comprehensively. Yang Rui really admires it, and those who can think of this layer estimate that most of them have done this kind of thing.

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

Without introduction, Yang Rui recognized two of them.

He has read a lot of genetic engineering journals recently, and scholars with names and surnames are indispensable to hang their profile pictures on journals and magazines.

So many people, greeted separately, and there was a flustery, and when it was clear, please enter the door, and there would be no more in half an hour.

Yang Rui sighed secretly, and he had to thank everyone for coming, and the fact is the same, if it weren't for the success of his face brushing, there would be no good things for the sages now.

Of course, the success of the experiment is a good thing, but the failure of the experiment is not necessarily the case.

This is also the reason why Yang Rui did not make a big deal about it, but he wanted to release satellites in public and control the scale, but Yang Rui couldn't control such a good thing.

Fortunately, in front of the experimental table, Gu Qiang and Ouyang Shi were calm, after all, they were people who had seen a big scene, and they were not intimidated by a hundred or so people.

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

Invite the veterinarians of the veterinary research institute of the animal husbandry corporation to prove the difficulty of embryo transfer, has reached the requirements of the commercial level, of course, this premise, is embryo segmentation, culture preservation and other technologies, are completed by the genetic engineering laboratory.

However, for the head office of animal husbandry, as long as the goal can be achieved, they do not care how it is done.

Dr. Wang, please give the recipient rat a general anesthetic first. Yang Rui asked Wang Jiancheng to do the preface steps first, even if there was a mistake, just change the group, and it would not affect the final success rate.

Wang Jiancheng was stunned for a moment, hurriedly agreed, and took out sodium amobarbital from the test rack 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. But Wang Jiancheng has done scientific research all his life, and he has never operated under the gaze of two academicians and dozens of well-known scholars, so he can't help but feel a little stiff.

Fortunately, the requirements for his operation are not high, and the husband of the mouse will not be troubled because of his injection method.

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

Yang Rui immediately ordered, and made an incision in the midline of the abdomen, exposing both sides and uterine horns.

This part is also Wang Jiancheng's operation.

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

Completion of an experimental group group.

The process was a little dull, but the atmosphere was always tense.

By noon, all the announcements were over, and Yang Rui also breathed a sigh of relief, and said: By the afternoon, the proportion of live fetuses can be determined.

The quiet environment in the laboratory was swept away, and the scholars immediately threw out the words that had been saved in their stomachs for a long time, but the content was not all in support of Yang Rui.

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

Where would it be so simple.

Even if there are no live fetuses, this experiment is worth referencing.

If there is no live fetus, it should be pushed to start over, in my opinion, the experimental conditions on Yang Rui's side are still not enough.

Embryo segmentation and frozen embryos at the same time are a bit too fast. When the time comes, it is not clear which side is wrong.

This makes sense, there are only a few laboratories that can do embryo segmentation, and then freeze embryos

Although Gu Qiang is an experimental operator, he is actually not optimistic about Yang Rui's experimental design, and he has little confidence in the results.

However, Gu Qiang still couldn't help but say in his heart: at least one life, at least one life

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