Chapter 1462

"I did it myself before, but the operation is not good. If you operate it, the effect should be better." Yang Rui said, occupying the position of the microscope, casually ordered a person and said: "bring me a group of egg cells."

The unnamed dog ran to the refrigerator and handed in a set of eggs.

Yang Rui took out one and looked at it. He was sure there was no problem, so he picked up the needle to remove the nucleus.

As far as the experimental level is concerned, Yang Rui can only be said to be a moderate qualification. In recent years, he has done more, but he has become more proficient. However, he is also a skilled moderate level.

It doesn't show up in experiments with low technical requirements, but there is no middle way to go in cloning experiments.

It's just like an ordinary mechanic, who is competent for ordinary repair tasks, is not much weaker than a senior mechanic. However, in the face of difficult repair tasks, the gap appears.

Yang Rui in the sheep cloning project, very few hands-on, but also the level of self-knowledge is limited, as clumsy.

However, technical guidance or technical presentation is another matter.

He is now more to show his new technology model than to pursue results.

In fact, if we can pursue the results, Yang Rui is lazy to guide anything. This is true of many professors in universities, especially those with high operation level. Sometimes they really prefer to do experiments by themselves rather than teach students or exploit experimental dogs. In short, when the level of experimental dogs is too different from their own, experimental dogs have no value for exploitation.

Yang Rui is out of the realm of pure experiment.

In fact, it's really hard to do simple experiments, especially boring and repetitive experiments. For example, it's normal to do the experiment of removing and injecting nuclei in one round, which takes half a day. It's a great test for people's physical strength and spirit to do it repeatedly every day, dozens or hundreds of times.

However, technical guidance or technical presentation is not the same.

It's more like technology development.

It's better to be a designer of machine tools than anyone who doesn't need to operate them.

Designers who design clothes don't have to show models.

In the same way, biologists who have developed new technologies do not need to do experiments, and their level is higher than anyone else. Basically, it's good to be able to show the newly developed technology.

Yang Rui has some confidence in this. No matter what, he is also a scientific researcher who has received systematic training and experienced for several years.

Su fan was also very confident in Yang Rui, and boasted to Wang Liangcai in a low voice: "when we were in the ion channel laboratory, Professor Yang often presided over experiments."

"I thought you were mainly experimenting with Gu Qiang." Wang Liangcai also asked by the way.

"Where is Gu Qiang?" Su Fan said unconvinced: "Gu Qiang is a member of Haidian District genetic engineering laboratory, and later transferred to our ion channel laboratory. Besides, there are many strong people doing experiments in our laboratory, but they are not as lucky as him. "

"Gu Qiang seems to be lucky." Wang Liangcai said so.

Su Fan said: "he can't live on luck for a lifetime. To tell you the truth, Professor Yang has done many experiments himself. You know why our laboratory is called ion channel laboratory. "

"Professor Yang is the pioneer of potassium channel research." Domestic scholars naturally know a lot about Dana in the circle.

In fact, if we persist in the study of ion channels for 20 to 30 years, it will be enough for Yang Rui's laboratory to become a vassal.

At present, although the time is still short, the research of ion channel laboratory is still world-class and domestic leading.

Yang Rui recruited so many calves to stay in the laboratory steadily because there are so many basic jobs to do. Otherwise, no matter how well scholars are paid, there will be no room for them to stay.

Over the past few years, Su fan's work in the laboratory, in addition to cloning cells, is to continue to do research on various ion channels, familiar with the way: "Professor Yang was on his own, through ion channels. Therefore, Professor Yang's experimental ability is also very strong. "

"Well... It's pierced." Standing in front of the experimental table, Yang Rui suddenly said a word.

Su fan and Wang Liangcai were surprised to see that Yang Rui picked up the oocyte under the microscope, discarded it and replaced it with another one.

Needless to say, his enucleation needle must have pierced the nucleus, so that the cell completely failed.

Su fan can't help but blush. Before a set of oxen have been blown clearly, Yang Rui's needle has been punctured by him.Yang Rui didn't feel it at all. He wasn't very good at experiments, let alone genetic technology. It's not a mistake to expose an egg cell.

After repositioning an oocyte, Yang Rui continued to hook his head and operate under the microscope.

Wang Liangcai did not speak, and continued to pay attention to Yang Rui's operation.

Su fan coughed twice and said, "Professor Yang probably didn't do the experiment for some time. He gave birth to it by hand..."

"He was exerting too much force just now." Wang Liangcai did relevant experiments every day, and could guess what happened to the egg cells without a microscope. The enucleation needle must have punctured the spindle.

However, from another point of view, it shows that Yang Rui's method is very likely to be realized.

The thickness of the spindle is certain. Of course, some annoying oocytes have thinner or thicker spindles. But what does it matter? Just give up the oocytes.

Therefore, the fact that the enucleation needle touches the spindle itself proves that Yang Rui's method has a chance to succeed.

Wang Liangcai approaches some experimental tables and stares at Yang Rui's hand. He doesn't pay attention to Su fan any more.

Su fan was a little surprised at Wang Liangcai's expression. After thinking about it, his expression became dignified.

If the new plan is as understated as Yang Rui described, it is self-evident for the promotion of the cloning project.

At least, the need for luck is much less.
