Chapter 1080

Genetic engineering laboratory.

After Gu Qiang carefully did the verification, he began to understand the steps of freezing, almost without any delay.

In theory, embryos preserved in liquid nitrogen can last for decades - of course, because the total length of time is not enough, scientists of 85 years can only guarantee that they will be alive for more than 10 years.

However, the theoretical "shelf life" does not mean the best time.

For commercial embryo transfer, survival rate is the more important indicator.

Therefore, it is usually the right choice to use embryos as quickly as possible.

Several researchers from the Institute of genetics seemed to want to say something, but they didn't think about it.

Yang Rui and several other researchers, together with Comrade George said from the United States, watched Gu Qiang's operation carefully.

The genetic engineering laboratory was quiet, with the sound of instruments and utensils.

When Jiang Zhijun came in, he saw such a harmonious scene.

About 30 minutes later, the thawed embryos were transferred to the first Simmental.

Including Gu Qiang, everyone was quietly relieved.

Jiang Zhijun took the opportunity to get close to Yang Rui and said with a smile, "why do you still use Simmental? Isn't it OK for ordinary domestic cattle? "

"Make a comparison." Yang Rui explained casually and asked, "have you discussed it?"

"Lao Ding let me take full responsibility." Jiang Zhijun has the final say that he said it. Their biological service company was originally three shareholders, Jiang Zhijun himself, Ding Shiyi and Wen Zelin. If Ding Shiyi authorized him, Wen Zelin said nothing.

Yang Rui nodded, but he didn't care much. He didn't join their company at the beginning, just tired of this kind of organization and personnel, and now he has no interest in joining.

Jiang Zhijun coughed lightly and continued: "you have done this job at home before, but now how much does it cost to import it from abroad?"

"300 dollars for an embryo." Yang Rui replied: "the price offered by the ranch of the University of Colorado is the lowest they can give.

Jiang Zhijun's brow immediately wrinkled, even a little angry. He adjusted his mind and said, "this price is enough for us to find foreign technology service companies."

He also knows the price.

Yang Rui nodded slightly and said, "this is the embryo from abroad. Naturally, it is the price of embryo from abroad."

"What do you mean? Is the project your lab is doing to replace foreign embryos

"This is to use foreign embryos for verification." Yang Rui looked at Jiang Zhijun with the expression of looking at a fool, and said: "it's like doing medicine. If you want to do a large number of clinical trials, animals also need to do clinical trials. Of course, embryo transfer is not a medicine

Jiang Zhijun didn't understand it very well. He continued to frown and said, "what's the purpose of verification? Is that necessary? "

"We have to prove that the embryo transfer we do in our laboratory is no worse than that from abroad." Yang Rui pause for a while, and then said: "our domestic companies may not have requirements, but foreign companies or ranches have requirements, so take precautions."

Jiang Zhijun ignored the first half of what Yang Rui said, but he suddenly heard the second half of what he said.

Yang Rui also wants to sell technology to foreign companies.

This is not surprising. Yang Rui had such a plan at the beginning of establishing the genetic engineering laboratory.

However, Jiang Zhijun thinks that should be a few years later - normal thinking, shouldn't we do it in China for a few years, wait for the technology to improve and the operation to be stable, and then consider the foreign market?

Even if the first bovine embryo transfer was not completed, they planned to show their technology to foreign companies—— If others say this, Jiang Zhijun will probably laugh.

But now he can't laugh.

Jiang Zhijun believes that Yang Rui has this ability.

In fact, any company that can provide commercial embryo transfer is world-class.

Jiang Zhijun has learned a lot about the company since he founded it. Now he knows that although there are many companies involved in embryo transfer in the world, some of them are world-class multinational companies. However, the companies that can really carry out large-scale commercial operation are only double-digit companies. Moreover, some companies will also provide technical services to multiple multinational companies at the same time

Therefore, Yang Rui is a world-class biotechnology service provider as long as he can complete commercial embryo transfer.Furthermore, if Yang Rui provides some embryo and embryo transfer technology to Jiang Zhijun's company, their company will be able to compete with world-class multinational companies. If not, their company will be at the end of nowhere.

"How's it going?" Yang Rui's voice interrupted Jiang Zhijun's reverie.

"No problem." Jiang Zhijun said the number of Simmental cattle.

"Go ahead, finish as soon as possible." Yang Rui looks at his watch. Normal embryo transfer takes about 30 minutes to complete. If it's fast, it takes 20 minutes. If it's 10 Simmental cows, it takes five hours.

Gu Qiang wiped his sweat and continued to operate.

He made a small incision on the side of the cow's rib to transfer embryos into the body.

Two veterinarians standing behind him looked at the operation of 001, then stared at the operation of 002 for a while, and almost learned.

However, they can't practice on Simmental.

Almost by the time Guqiang reached 005, several local cattle were brought over and became the first experimental objects of two veterinarians.

"Together?" Jiang Zhijun feels that he can't keep up with Yang Rui's ideas.

"Of course. More than 200 cows. " Yang Rui looked at his watch and said, "if there is no problem, we can have a rest. It will take a few days. "

"Oh... Oh..." what Jiang Zhijun wanted to say, but he didn't know what to say.

It is obvious that the cattle were all sent by China animal husbandry Corporation, five and ten at a time. They were sent by a car, and the cattle that had been transferred and numbered were taken away by the way.

Because the pastures of Zhongmu are close to each other and they are going to repeat, they will send two cars in turn to meet their needs.

The first large-scale embryo transfer in the whole laboratory had the feeling of assembly line.

Jiang Zhijun trembled with envy, excitement and excitement.

At this time, Yang Rui said to himself, "do you know why I want a 1000 mu ranch? Today's laboratories can't hold more than 200 cows at all. As soon as these cows have finished embryo transfer, they have to be transported away. If they are in trouble, the success rate must be reduced. "

"As long as the success rate is more than... More than 40%..." Jiang Zhijun seemed to answer and chant a mantra.

Yang Rui was not moved, and said: "using foreign embryos, more than 40% does not count. We have to use our own embryos."

Yang Rui said, and then went back to order.

Jiang Zhijun didn't know where to look.
