Chapter 1004

Yang Rui came to the laboratory early, ate a vegetarian bun made in a small canteen, and drank a bowl of hot mutton soup. Then he came to his experimental table and began to inspect the equipment.

The microscope, scalpel, incubator, inactivated serum, agar bag and so on have been placed properly.

Yang Rui checked every tool, and half an hour passed.

"It's good. There's no problem with the new equipment. ANN is very good." Yang Rui praised it.

There was no such equipment on his test bench before, but the advantage of being the director of the laboratory is that as long as the laboratory has the equipment, he has the priority to use it, and can use it on his own desk. Even if the laboratory does not have relevant equipment, he can give priority to procurement and equipment.

Wang Wang Lei, who is in charge of the scientific research, was relieved and said with a smile: "I'm all in accordance with the highest standards. In their instructions, the error is 1 mm to 3 mm, so I asked them to adjust it to 1 mm. A few people stayed up all night and sent a teacher to do it well."

"Will they?" Yang Rui also noticed the error and was quite satisfied.

"I said that they can't make it according to this standard. We can't use it. We can only buy foreign instruments. It's not that they don't support domestic instruments. They can't help it. It seems that the director leads the team himself. "

"It's a little smart." Yang Rui smiles.

85 In 1997, there was no scientific equipment company with good service, but the state-owned equipment factory was quite active. The era of self financing has come. Light industry manufacturers who don't worry about sales don't have to worry about services. Factories facing enterprises and institutions have already felt the east wind of reform. In order not to be blown to pieces, they can only try their best to carry out the work they used to be good at, for example, to the good of the person in charge of the laboratory.

Nowadays, it is a common practice to give gifts and drinks to Party A. Yang Rui has met many drunken laboratory directors.

He himself is not interested in being invited to dinner. Correspondingly, he has high requirements for instruments and equipment, and state-owned manufacturers will arrange as soon as possible. The mode of technology director reporting in ion channel laboratory and sales director reporting in Logistics Department has appeared in many domestic instrument manufacturers.

It's rare that laboratories that can produce world-class results are willing to use domestic products. Although Yang Rui doesn't use many of them, all instrument manufacturers cherish them and try their best to deliver first-class products.

If we do it carefully, we can still bear the heavy responsibility.

However, reagents are very unpopular.

Su xiankai and Wang Lei left, then came over and whispered: "director Yang, if you want me to say that domestic instruments can be used, but reagents can be used or not... We should have no shortage of funds now."

"Is there a time when there is no shortage of funds for scientific research?" Yang Rui made a joke.

Su xiankai was stunned and asked, "is there something wrong with the funds?"

"The same as before." Yang Rui said casually. Looking at Su xiankai's dignified expression, he added: "if you can save, you can save. After eating white noodles for a few days, you can't drink corn paste?"

Su xiankai said with a bitter smile: "I'm not afraid to drink corn paste. I'm afraid that something will go wrong when doing experiments. Director Yang, it's really not me who discriminates against our domestic reagents. What do you say they make? The analytically pure reagents are not as clean as the foreigners' chemically pure reagents. The same batch of reagents, doing the same experiment, can't reproduce... I'm a grass! "

Su xiankai said and began to scold.

Experimental reproduction is a very important step. Experiments that can't be reproduced are not only easy to fall into the vortex of counterfeiting, but also make researchers at a loss. Because you can't reproduce the experiment, you can't continue the next step of research, unless it's a verification type experiment, but the verification type experiment can't be reproduced. How can you explain that you have verified it.

The first problem caused by impure chemical reagents is that you don't know whether the reagents you use or the impurities in the reagents work.

It's like the story of a catalyst. You know that 1000 liters of ammonia will react. If there is no platinum rhodium alloy catalyst that is hard to see by naked eyes, the ammonia will never turn into nitric oxide.

If the chef's salt is contaminated by unknown seasonings, and the seasonings of the contaminated salt are constantly changing, how can he make delicious food.

Analytically pure chemical reagents were supposed to be condiments with little pollution. However, the domestic manufacturers in the 1980s obviously did not reach very few standards.

This kind of problem will not be solved 30 years later. At that time, domestic manufacturers will naturally make progress, but few standards will be more stringent.

When Yang Rui went to graduate school, he also hated domestic reagents.Because students do experiments, they usually only get domestic reagents, which makes the road of experiment more bumpy.

The ion channel laboratory used to use imported reagents, which is the key for Yang Rui to attract and retain many researchers.

However, the newly-built genetic engineering laboratory can not use imported reagents, because its first stage goal is embryo transfer, and it is a commercial embryo transfer. If all imported reagents are used instead of domestic reagents, the cost will soar by more than 10 times, and the business will be out of the question.

China animal husbandry Corporation invited the Research Institute of the Chinese Academy of Sciences to do the corresponding research on embryo transfer. The problems encountered also include these. High end technicians can complete the experiment of embryo transfer by using imported high-end instruments and imported high-end reagents. However, in the pasture environment, it is impossible for 100000 embryos to be transferred in this way every year.

At this time, see Su xiankai are angry, Yang Rui quickly comfort way: "domestic reagent is for the new experiment preparation, you don't nervous."

"New experiment?" Su xiankai took a look at the equipment on Yang Rui's desktop and asked, "the genetic engineering laboratory you made?"

"Yes."

"So... Ha ha... I say, the canteen we just made won't be poor all of a sudden..." Su xiankai touched his head with a smile and said to himself: Fortunately, he didn't say that the canteen had been cancelled, so he quickly ate a pot of braised pork at noon.

Other researchers in the laboratory are also relieved.

Nowadays, it's normal for a good scholar to master several laboratories, and the researchers in the laboratory are often mobile. For researchers, the bigger the boss is, the more comfortable he is. However, if the big price is to reduce the treatment, it needs to be considered.

"Gu Qiang, give me a hand." Yang Rui looked at the experimental equipment and materials available, will Gu Qiang to call over.

His experimental technique is not so good at all, especially in genetic engineering. It's too late to practice now. It's better to use other researchers.

Gu Qiang mixed up in the ion channel laboratory these two days. His chin was raised again. Shi ran came over and asked, "what do you do?"

We can't see anything good or respectful.

Yang Rui silently read a "I endure", said: "I designed an experiment, you do a look."

"Why don't you do it yourself?" Gu Qiang choked Yang Rui with a word.

Yang Rui twitched his mouth and said, "I want you to do some fine operations to avoid the failure of the experiment due to the problem of experimental technique."

"You don't trust your own experimental techniques. What else do you design? Let me see." Gu Qiang said as he reached for the folder in Yang Rui's hand.

This is what Yang Rui can't bear. He received the document behind his back and said, "researcher Gu, this is the first work that the laboratory has given you. If you don't want to do it, just put it forward."

"I don't want to do it." Gu Qiang put it forward.

Yang Rui lowered his head to avoid killing Gu Qiang and polluting the experimental platform.

"If you don't want to do it, you won't be of any use to my lab either." Yang Rui raised his head again with a more serious expression.

This time, it was Gu Qiang's turn to twitch his mouth twice. After thinking about it, he said, "if you want me to do the experiment, you must show me the design of the experiment. Otherwise, how can I adjust the technique in the process of my experiment?"

"Today's experiment is not the same. I said, you can do it. It's not successful... If it's my problem, besides, if it's your problem..."

"I can't have a problem." Gu Qiang, if you can't beat me to death, I'll show you.

Yang Rui tolerated it again. He said in his heart three times that I must develop mature technology and eliminate this product.

After three times of reading, Yang Rui felt much better. He directly ordered: "today, we are still doing embryo segmentation. The experiment number is pt001. The goal of segmentation is to segment mouse embryos, then freeze them, and finally save them for later transplantation experiments. The first step today is to split the mouse embryo

As soon as his voice fell, Gu Qiang raised a loud objection: "I can do the embryo segmentation by myself, but freezing can't. the transfer of frozen embryos is a big topic. Are you just starting the project so hastily?"

"In the first step, the embryo was sucked by a fixed needle in a medium free of calcium and magnesium ions. Do it. " Yang Rui doesn't explain at all, but treats Gu Qiang as a noisy robot.

Gu Qiang resisted with words, but still moved obediently.

……"Longwu 2" invited me to participate in one of their starting point legitimate reading plans, and sponsored 1 million starting point coins to support our legitimate reading. On September 23, the game was not limited to number test, so I could get starting point coins if I entered the game. I think it's not bad.

As for playing this game, I have an idea. How about building an army of birds together? Now you can pre create characters. I built a dolphin named "shiniao" in [Shenzhou] district. Everyone's names are all marked with the word "shiniao". On September 23, the landing game can kill the enemy together and get some starting coins.
