Chapter 1451

"If you have seen the documents in your hand, you can come to my place to line up and do the experiment." Xu Zhengping stepped onto the stage and made the test more elegant.

Some scholars who knew him were already in a slight commotion.

Three or four years ago, few scholars from other places knew Xu Zhengping. He was just an associate professor of Peking University. Even if he met in various conferences, it was hard to leave a deep impression.

However, the performance of ion channel in Peking University in the past two or three years, Xu Zhengping's signed papers frequently appeared in major journals, coupled with Xu Zhengping's identity as deputy director, gave him many points, so that many people remember Xu Zhengping's name.

The appearance of Xu Zhengping means that the ion channel laboratory is in charge of the national project, and the person in charge of the project is likely to be Yang Rui, which makes many people secretly happy.

Wang Liangcai also relaxed.

If the domestic biological projects are listed in a table, the ion channel laboratory is basically at the top of the list. The projects Yang Rui supports are among the best. At this time, Yang Rui's age is not under consideration.

With all the Nobel prizes, youth is just an advantage.

The most important thing is that the projects that Nobel laureates want to do and the support they can get must be the top in China. If not, they can still reach the top level in the world.

This is a rare opportunity.

Wang Liangcai lowered his head and read the document carefully.

"Peeling off the membrane of egg cell" -- seeing the document, countless pictures instantly appeared in Wang Liangcai's mind.

Students studying genetics in China are not familiar with this topic. This is because Tong Dizhou, a veteran of Chinese genetics, started his career from this.

For Wang Liangcai, that's more familiar.

He can still remember the scene of the old boy's hand-in-hand teaching experiment.

If it's a bit bigger, the peeling of egg cell membrane can almost be regarded as the jumping-off step of Chinese genetics.

This is because Tong Dizhou started his career with this technique. According to legend, the mainstream genetics circles in China, especially the aquatic genetics circles, basically take this kind of practical training project as a compulsory course. It's a natural pattern that the good ones are benchmarked against the high-end ones, and the bad ones are ranked below.

For the research dog without background, the high level of experimental operation is certainly not at a loss.

Tong Dizhou studied abroad in 1930 when Martin Luther King was only one year old. We can imagine the racial discrimination in the white world in Europe and America at that time.

Tong Dizhou was naturally despised and rejected in Brussels, so that he wrote in his diary: the Chinese are not stupid, they should take things out to win glory for our nation.

If he was not bullied, he would not vent his anger in his diary.

If he didn't have nowhere to vent, he wouldn't have to write in his diary.

What Tong Dizhou did was to peel off the egg cell membrane. Of course, it's not any kind of egg cell peeling, but frog egg cell peeling.

In the 1930's, no one had done egg cell dissection for frogs. The egg membrane of frog eggs is soft and thin. There are three layers in all. It is extremely difficult to operate under the microscope. If you don't pay attention to it, you have to do it again.

Even well-trained experimenters are hard to deal with frog eggs the size of small grains of rice.

Tong Dizhou took it as his goal and worked overtime until 2 p.m. every day. Finally, practice makes perfect. He peeled off the egg membrane of frog eggs cleanly and immediately stood out from countless students.

His professor didn't care about Tong Dizhou's yellow race identity. He took him to the famous seaside laboratory in France to do the outer membrane peeling of ascidian eggs. It was only one tenth the size of frog eggs, and he was still the first one to finish it. From then on, he went to the peak of his life.

Up to now, many key points of these experiments have been thoroughly studied. It is much easier to say, but it is still a very difficult technology. For example, heart surgery can be done many years ago, but it has never been easy.

Wang Liangcai used to operate this kind of experiment. In recent years, his research direction has changed a little, so he looked at the document and reviewed it.

Looking carefully, Wang Liangcai found some different places.

The main points of the operation of this experiment seem to be more detailed, and there are many different places.

Wang Liangcai couldn't help being interested.

It is easier said than done to revise the main points of the experiment.

Not to mention writing books and setting up biographies, revising an experimental method is the result of several times of deliberation. You have to see if you have such a big face firstThinking of this, Wang Liangcai immediately turned to the back to see the author of the pamphlet.

"It's Yang Rui." Wang Liangcai murmured to himself.

The face of a Nobel laureate is big enough, but to modify an experimental method, you have to be quite familiar with it.

Some scholars have done an experiment all their lives. After doing it all their lives, they can only say that the modification of the original experimental method is sewing and mending. This is like a professional doctor who has done many cases of heart bypass surgery. He may have done thousands of cases of heart bypass surgery all his life, Furthermore, if we make the modified surgical plan more general, there will be too little we can do.

Although Wang Liangcai did not peel off the egg cells for several years, his accumulated knowledge is not outdated. When he looked at it with a scanning eye, he found many similarities and differences.

Yang Rui has not changed a lot, but he has changed a lot in key positions.

Some of the changes, in Wang Liangcai's view, are serious, but others are less understandable.

If the author of the pamphlet is not Yang Rui, but some other unknown guy, Wang Liangcai will not work hard to read it. However, with the name of the Nobel laureate printed on it, it can't be so casual.

Fundamentally speaking, Yang Rui, a first-class scholar, can already be called a rule maker in the scientific research world, while Wang Liangcai, a fourth-class scholar who is not even a rule maker, is a rule protector.

What the maintainer has to do is to understand and run the rules made by the rule maker?

Wang Liangcai frowned and pondered the contents of the pamphlet, forgetting the time.

"Professor Wang, it's your turn." Xu Zhengping came to the front with a smile.

Wang Liangcai raised his head and said, "can you ask others to do it first?"

"It's just you." Xu Zhengping road.

Wang Liangcai was shocked to find that he was the only one sitting in the classroom.

"Sorry, sorry." Wang Liangcai quickly stood up.

Xu Zhengping shook his head with a smile and said, "it's OK, but let's do the test first. If you join the project, you will have plenty of time to study in the future. In our lab, we encourage people to think deeply. "

Wang Liangcai then packed up his things and followed Xu Zhengping into the laboratory next door.

The laboratory for testing, things are moved temporarily, it looks a little irregular.

Wang Liangcai looked at the furnishings of the room with a little disdain. When he came near, he saw the sign on the microscope. He was surprised and said, "is this a real Zeiss lens?"

Later generations all know that SLR destroys life, photography is three generations poor, because the lens of camera is more expensive, the price of tens of thousands of yuan or even hundreds of thousands of yuan is amazing.

But after all, civilian products are civilian products. If the most professional and expensive lens is not used for paparazzi's follow-up shooting, it will only be wasted by the art students who have no eggs. Its ultimate value is to collect funds for manufacturers, so that they can have enough funds to invest in optical microscope, laser confocal microscope, X-ray microscope and super-resolution microscope, Development of scanning electron microscope.

In the world of scientific research lens, hundreds of thousands or millions of them can only be regarded as the starting price at most. The most important requirement of Shi Yigong when he returned home was to have a cryo electron microscope, so Tsinghua University spent 6 million dollars to buy a set for him.

And for the most common optical microscope, there is a chain of disdain.

For example, the reason why ordinary laboratories don't use the lenses of Zeiss and Leica is not that they can't afford to use them, but that they can't use their projects. Of course, they can't afford it.

Wang Liangcai couldn't help touching the name plate on the lens. He woke up and apologized: "sorry, I didn't mean to..."

"It doesn't matter. It's just for you to prepare for the test. If you pass the test, these are standard configurations." Xu Zhengping can understand Wang Liangcai's idea very well. If he didn't want to be a cloned sheep, he would not agree with Yang Rui to buy such a lens.

It's such a fuckin 'waste.

But, it's so fuckin 'fun.

Wang Liangcai was even more excited. He rubbed his hands and said, "tell me, whose egg are you going to peel?"

In the laboratory, those with eggs feel a chill in their crotch.
