Rebirth of the God-level Xueba

Rui Yang's genetic engineering laboratory reopened.

This time, Haidian District prepared Lun's ceremony for him and invited many guests.

Yang Rui does not object to this ceremony either. The so-called weather update, he also needs everyone - mainly partners, to know that the situation has changed.

A practical laboratory is different from a laboratory doing basic research. Tongchao said that the more profitable a laboratory is, the more external support it needs. For example, a genetic engineering laboratory, when using mice and rabbits for experiments, can also be raised in the basement or yard at its own expense. Here, when using cattle as a laboratory, it is unlikely to be entirely on your own.

If the area is larger, such as fine-bred monsters, it cannot be completed by a single animal husbandry. Fifty years ago, the British and the Japanese conducted similar research worldwide with the power of the whole country.

For Yang Rui's genetic engineering laboratory, a large amount of donations and the sale of technical products are still necessary.

In contrast, the ion channel laboratory is much simpler. In addition to the difficulty in applying for funding, the base cluster laboratory is still more generous when it comes to spending money.

Of course, it is not a bad thing that a practical laboratory needs external support. The diversification of resources always makes it easier to develop practical laboratories.

In fact, the replacement of the laboratory with the type is originally very fast. This also means that its resource consumption is very large. If it cannot find the correct location, it will soon fail to cycle.

The North China Animal Products Research Institute is an obvious example. They rely on national resources to build practical laboratories. Once they are weaned, they can no longer persist.

Even though Yang Rui had seen many similar examples in textbooks, he was deeply touched by his personal experience. When he saw Mr. Mei and others from China Animal Husbandry Corporation, he couldn't help but put on a friendly smile on his face.

In the eyes of Director Mei and others, this is a sign of enthusiasm.

Think about Yang Rui, shooting wild boars while talking and laughing, and being so enthusiastic about dealing with people, the future is really limitless. Director Mei thought as he held Yang Rui's hand tightly, and said, "It's good that Director Yang comes back, we The entire China Animal Husbandry Corporation supports Director Yang."

Yang Rui smiled brighter, but said: "I am relieved when Director Mei said that, our genetic engineering laboratory has resumed research work, and after waiting for the 1,000-acre pasture, all the research elements will be fully active. "

Just say a 1,000-acre ranch when you meet? Director Mei was in a daze, Yang Rui let go of his hand with a smile, and greeted others.

"This guy..." Director Mei looked at Yang Rui's back, dumbfounded, and said, "I just got it back from the laboratory, so I'm so big-hearted."

"Then are you going to give it or not?" Director Tie stood in the shadows, with a strong inverted triangle like a superhero.

When Director Mei saw his old classmates, his expression immediately returned to his school days. His eyebrows were not eyebrows, and his eyes were not eyes. Already? If the head office votes, I’m definitely in favor.”

"You don't even have the qualifications to initiate a vote. What do you say you have done these years? The more you get around, the more you go back." The iron director from Qingmu spared no effort to ridicule his old classmates.

Director Mei said "hey" to Beijing, but when he wanted to continue, he wisely shut up and said, "The results produced by the genetic engineering laboratory should be shared by all units, right? Why don't you just say take 1,000 mu out of the pasture?"

"If Yang Rui moves the laboratory to my site, let alone 1,000 mu, I can afford 10,000 mu."

"That's because your ranch is worthless." Director Mei snorted twice, and said, "The capital is worth every inch of land, you know?"

"It's as if you are supporting cattle in Guangzhou." Director Tie curled his lips: "Aren't you a cattle herder?"

Yang Rui greeted the guests unconsciously.

The "men" are mainly cadres of the Haidian District and the Municipal Party Committee and Municipal Government.

A laboratory, the sky is turned upside down, is still a laboratory, that is, what happened to Lu Shou, the Haidian District Government, whether it is to express apology or to express importance, many people came, He also re-signed with Yang Rui in a serious manner.

The main content of the contract was to hire Yang Rui to take full charge of the work of the genetic engineering laboratory in Haidian District. Since Yang Rui didn't need to prepare the work, it was very easy to sign such a contract.

The contract period was set at 10 years, but Yang Rui didn't care.

At his current level, in fact, it is more important to practice internal skills and develop external skills.

Internal strength is research and management ability, and external strength is to improve one's face and reputation.

A simple laboratory, no matter whether it is worth millions or tens of millions, in the final analysis, requires researchers to operate. China in the 1980s was short of money, but in fact it was even more short of people.

For example, the Haidian District Genetic Engineering Laboratory was able to attract Li Xingzhou and Lu Shou to join in. It was Yang Rui who made the results, which was the result of internal strength. And Yang Rui's opportunity to use his internal skills was made possible by donations from various companies. What the companies saw was Yang Rui's external skills.

Otherwise, relying solely on the allocation of funds from Haidian District itself, it is estimated that it will not be able to achieve results in the 21st century.

Of course, if someone else comes in, even if they have sufficient funds, they may not be able to do it to a certain extent.

This is the cooperative effect of internal strength and external strength.

What Yang Rui cares more about now is the process of researching the results and the results derived from the results.

In the future, no matter which laboratory he goes to or continues to control the genetic engineering laboratory, what everyone will look at is the process and achievements.

The process is to see if he can repeat his own achievements, and the result is to see whether his research direction is valuable.

It is the genetic engineering laboratory itself, which is actually part of Yang Rui's achievements.

If the 1,000 mu of pasture falls to the genetic engineering laboratory, after decades, if Yang Rui still controls the genetic engineering laboratory, this will naturally be an important resource. See it as his achievement, which not only shows his vision, but also can polish his resume, just like the previous heads of Cavendish Laboratory, whether it is a sequential retiree or a change of family, people see them When I was studying, I would still refer to the Cavendish Laboratory at that time.

Compared with the curiosity of government officials and state-owned enterprise cadres, the mood of the researchers in the laboratory is really exciting.

The genetic engineering laboratory has been shut down for a long time, and everyone is even ready for the laboratory to become obsolete. Now, so many people participated in the ceremony for the reopening of the laboratory, but it gave the researchers a reassurance.

After a few slanted welcomes, everyone quickly entered the state of scientific research.

Yang Rui is even more so.

He didn't expect to rely on Mr. Qiao's "appreciation" for a lifetime, besides, Mr. Qiao's "appreciation" was originally aimed at his academic ability.

Yang Rui didn't even take advantage of the opportunity of hunting wild boars to force donations, because he knew that as long as the results were produced in his laboratory, donations would only continue, and he didn't need to force them at all.

"Gu Qiang, you use the direct segmentation method with a microscopic scalpel to segment embryos. Ouyang Shi, start a new project on your side, and we will compete to overcome embryo sex identification technology during the competition." Yang Rui did not stand in the laboratory like a leader He held a mobilization meeting in Li, and his mobilization was to directly assign tasks.

Although there were a few weeks away from the experiment, the researchers in the 1980s were very conscious, and everyone was trying to find ways to grab time, and conducting theoretical research was a very familiar job.

Gu Qiang immediately agreed, and asked, "Do you want to determine the segmentation method as the microscalpel direct segmentation method?"

"I think this method has the most potential, what do you think?" Yang Rui clearly knew that this method was the most efficient, but discussions were still inevitable.

Gu Qiang thought for a while and said, "If I have to choose, I think the method of splitting with bare hands is the best."

"Oh why?"

"Because freehand segmentation only requires a special blade, and self-made blades are fine if you don't have one. Although the success rate is lower than that of the microscalpel segmentation method, the equipment requirements are low. If you want to expand in the future, the cost is not high." Gu Qiang It is very clear.

Yang Rui smiled and said, "You know how to control costs."

"In the past few days, I have read a lot of materials." Gu Qiang was a little proud.

"But you never thought about how much a Simmental embryo costs?" Yang Rui didn't just copy the research data, he also thought deeply, and said descriptively at this time: "The embryo of a mouse, We have as many as we want, Simmental embryos need to be purchased with foreign exchange, at the beginning it is uncertain how many there will be, no matter how low the cost of the equipment for manual division is, do you think the China Animal Husbandry Headquarters will stop the breeding?"

"With more training, the success rate of freehand segmentation is at most 5 percentage points lower than that of the microscalpel method." Gu Qiang reluctantly argued.

Yang Rui smiled and said, "I believe your success rate is so high. I'm going to find you two students. How long will it take you to bring their success rate to this statistic?"

Gu Qiang laughed twice: "It depends on talent."

He is an experimental genius, not everyone is an experimental genius.

However, Yang Rui's answer satisfied Gu Qiang's vanity, so he silently agreed.

"The task of embryo segmentation is entrusted to you. You not only need to practice it yourself, but also form a document to ensure that after a certain period of training, other technicians can achieve a similar success rate." Yang Rui said and looked at the Ouyang Shi.

Gu Qiang was a little anxious, and rushed to speak again: "I heard you tell them, didn't you say that the work of embryo segmentation should be done in our laboratory?"

"Of course it is done in our laboratory, but you don't have to do it. Otherwise, are you going to do embryo division in the next few years?" Yang Rui asked with a serious expression.

Gu Qiang repeatedly said that doing this kind of work once or twice is just pretending, but it would be miserable if it was done in daily work.

Yang Rui nodded and said, "You have to sum up your experience. It's best to break down the steps so that the technicians I recruit later can learn it. This is an important job to liberate yourself."

Gu Qiang looked solemn. He is quite willing to study the technology of embryo segmentation, but he shudders when he thinks about following the established steps for several years.

Then Yang Rui said to Ouyang Shi again: "Gender identification technology is our focus for the next period of time, and I will do it with you."

"Okay, which method do you want to try first?" Ouyang Shi said solemnly. The sex identification technology of embryos is not as simple as a B-ultrasound in the hospital to see if there is a ***.

If you want to use B-ultrasound to see the appearance characteristics, it will take at least four months for human beings. Even if you use B-ultrasound to see the gestational sac, it will take 6 weeks, that is, 40 days to 50 days.

Obviously, such a long time is not only inefficient but also meaningless for embryo transfer in cattle. The sex identification technology of cow embryos is used to sterilize male and female. For example, when beef cattle are needed, bulls are usually bred, but if the population is to expand, cows are bred. If it is not clear until a few weeks later, the cost of sex bred is too high.

Therefore, the sex identification technology of cow embryos does not use b-ultrasound at all, because the requirement is not months or weeks, but the number of embryonic cells is the limit.

As far as commercialization is concerned, the largest embryo that Shepherd and researchers can tolerate is 8 cells!

That is to say, when the bovine embryo splits into two from the fertilized egg, two into four, and four into eight, it is the final window for gender identification.

8 cells, in a detailed state that cannot be seen by the naked eye, it is necessary to distinguish between male and female. This difficulty is beyond the guesswork of a genius doctor.

However, in biology, many detection methods have been developed. Earlier ones included cytogenetic analysis, differential analysis of embryonic development rate, male-specific antigen detection and so on.

Although there are many methods, for the Chinese laboratory in 1985, none of them is easy and pleasant, and Ouyang Shi's dignified expression also comes from this.

Yang Rui is the best at doing this kind of question. He patted Ouyang Shi with a smile and said, "Let's try the x-chromosome-associated enzyme assay first, and the y-chromosome-specific dna probe."

"Huh? Why?"

"Because these two technologies were developed on the basis of pcr technology." Yang Rui pointed to himself and said with a smile, "it's not me. I'm very familiar with pcr technology."

The atmosphere that was a little serious just now became cheerful all of a sudden.

Ouyang Shi couldn't restrain his surging admiration, and suddenly shouted: "Long live Director Yang!"

Although others looked at him with surprised expressions, Comrade Ouyang Shi didn't care at all.

"Long live!"

"Long live!"

"Long live!"

The genetic engineering laboratory was filled with Ouyang Shi's lonely and surging voice.
