Rebirth of the God-level Xueba

"Everyone has read the documents in your hand, so you can come to me to line up and go in to do the experiment." Xu Zhengping walked up to the stage and said the test in a more elegant way.

Scholars who knew him were already slightly agitated at this time.

If it was three or four years ago, few scholars from other places knew Xu Zhengping. He was just an associate professor at Peking University. Even if he met in various conferences, it would be difficult to leave a deep impression on him.

However, the performance of Peking University's ion channel in the past two or three years, the papers signed by Xu Zhengping frequently appeared in major journals, coupled with Xu Zhengping's status as deputy director, gave him a lot of points, and many people remembered Xu Zhengping name.

The appearance of Xu Zhengping means that the Ion Channel Laboratory is in charge of the national project, and at the same time, it means that the person in charge of the project is likely to be Yang Rui, which makes many people secretly happy.

Wang Liangcai also relaxed all of a sudden.

If you make a list of domestic biological projects, then the ion channel laboratory is basically at the top of the list. The project supported by Yang Rui is even more top-notch. At this time, Yang Rui's age is not in everyone's consideration at all.

Having won the Nobel Prize, being young is only an advantage.

The most important thing is that the support that Nobel Prize winners will get for their projects must be top in the country, and if not done well, they can reach the top level in the world.

This is a rare opportunity.

Wang Liangcai lowered his head and carefully read the document.

"Egg Cell Membrane Stripping" - Seeing the document, Wang Liangcai's mind instantly had countless pictures.

Students studying genetics in China are not unfamiliar with this topic. Because the patriarch of Chinese genetics, Tong Dizhou started his career based on this.

For Wang Liangcai, it was more familiar.

He still vividly remembers the scene of Tong Lao teaching the experiment by hand.

If it is a little bigger, "The Stripping of Egg Cell Membrane" can almost be regarded as the take-off step of Chinese genetics.

Because Tong Dizhou started his career by relying on this trick back then, and it has been passed down from master to master. The domestic mainstream genetics field, especially the aquatic genetics field, basically regards this kind of practical project as a compulsory course. It is a natural model to benchmark high-end products if they are well done, and wait for those who are not well done.

For a scientific research dog with no background, the high level of experimental operation is definitely not a disadvantage.

Tong Dizhou studied abroad in 1930, and Martin Luther King was only 1 year old at that time. You can imagine the racial discrimination in the white world in Europe and America at that time.

Tong Dizhou was rightfully despised and rejected in Brussels, so much so that he wrote in his diary: Chinese are not stupid, they should come up with something to win glory for our nation.

If he hadn't been bullied so badly, he wouldn't have vented in his diary.

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

What Tong Dizhou did was to peel off the egg cell membrane. Of course, not just any egg cell stripping, but frog egg cell stripping.

In the 1930s, no one had detached frog eggs. The egg membrane of frog eggs is soft and thin, with as many as three layers. It is extremely difficult to operate under a microscope, and you will have to start all over again if you are not careful.

Frog eggs, which are only the size of a grain of rice, are difficult for even a well-trained experimenter.

Tong Dizhou took this as his goal, and worked overtime every day until two o'clock in the evening. Finally, practice made perfect, and he peeled off the egg membrane of the frog eggs cleanly, and immediately stood out from countless students.

His professor also ignored Tong Dizhou's identity as a yellow race, so he took Tong Dizhou to a famous French seaside laboratory to peel off the outer membrane of sea squirt eggs, which are only one-tenth the size of frog eggs , Tong Dizhou was still the first to complete it, and he has reached the pinnacle of his life since then.

To this day, many key points of these experiments have been thoroughly studied. It is much easier to say, but it is still a very difficult technique.

It's like heart surgery, it's been done years ago, but it's never been easy.

Wang Liangcai used to do this kind of experiment often, but his research direction has changed slightly in recent years, so he looked at the files and reviewed them a bit.

Looking carefully, Wang Liangcai discovered some differences.

The main points of the experimental operation in this book seem to be more detailed, and there are many differences.

Wang Liangcai couldn't help being interested.

Modifying experimental points is easier said than done.

Leaving aside the writing of books and biography, revising an experimental method is the result of several scrutiny. If you say revise, revise it. You have to see if you have such a big face...

Thinking of this, Wang Liang immediately turned to the back to see the author of the pamphlet.

"Sure enough, it's Yang Rui." Wang Liangcai murmured to himself.

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

Some scholars do one kind of experiment all their lives. After doing it for a lifetime, the modification of the original experimental method can only be said to be tinkering. This is like a professional doctor who has performed many heart bypass operations. He may I have done thousands of heart bypass surgeries in my lifetime, but if we want to modify the surgical plan and further make the modified surgical plan more generalized, there is too little that can be done.

Although Wang Liangcai has not done egg cell stripping for several years, the accumulated knowledge is not outdated. When he looked at it with a critical eye, he still found many similarities and differences.

Yang Rui didn't make many changes, but there were quite a few changes in key positions.

Some changes, in Wang Liangcai's view, are serious, but others are not so understandable.

If the author of the pamphlet was not Yang Rui, but some other unknown guy, Wang Liangcai would not bother to read it again. However, if the names of Nobel Prize winners are printed, it cannot be so casual.

Fundamentally speaking, a first-level scholar like Yang Rui can already be called a rule-maker in the scientific research world, while a scholar like Wang Liangcai, who is not even considered a fourth-level scholar, is a defender of the rules.

Isn't what maintainers have to do to understand and run the rules made by rule makers?

Wang Liangcai frowned, thinking about the contents of the pamphlet, completely forgetting the time.

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

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

"Only you are left." Xu Zhengping said.

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

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

Xu Zhengping shook his head with a smile, and said, "It's okay, but let's do the test first. If you join the project, you will have plenty of time for research in the future. In our lab, everyone is encouraged to do in-depth thinking."

Only then did Wang Liangcai pack his things, and followed Xu Zhengping into the laboratory next door.

The laboratory used for testing was moved here temporarily, so it looked a bit irregular.

Wang Liangcai looked at the furnishings of the room with contempt, and when he got closer, he saw the sign on the microscope, his eyes widened, and he said in surprise, "Is this the real Zeiss lens?"

People in later generations know that SLR ruins one's life, and three generations of photography are poor. Because the lens of the camera is more expensive, the price of tens of thousands or even hundreds of thousands of yuan is staggering.

However, civilian products are civilian products after all. If the most professional and expensive lenses are not used for paparazzi follow-up shots, they can only be ruined by useless art students. Their ultimate value is to return funds to manufacturers. Therefore, there is sufficient funds to devote to the research and development of optical microscopes, laser confocal microscopes, X-ray microscopes, super-resolution microscopes, scanning electron microscopes...

In the world of scientific research lenses, hundreds of thousands or millions can only be regarded as the starting price at most. Among Shi Yigong’s requests when he returned to China, the most important one was to ask for a cryo-electron microscope, so Tsinghua University spent 6 million US dollars. Bought a set for him.

As far as the most common optical microscope is concerned, there is also a chain of contempt.

Like Zeiss and Leica lenses, the reason why ordinary laboratories don’t use them is not because they can’t afford them, but because they can’t use them for their projects. Of course, they can't afford it either.

Wang Liangcai couldn't help but touched the nameplate on the lens, came to his senses in an instant, and hurriedly apologized: "Sorry, I didn't mean to..."

"It doesn't matter. It was originally for you to prepare for the test. If you pass it later, these are all standard configurations." Xu Zhengping can understand Wang Liangcai's thoughts very well. If he didn't want to clone sheep, he would not agree to Yang Rui buying it like this. of the lens.

So fucking wasteful.

But, it's fucking fun.

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

In the laboratory, those with eggs felt cold in their crotch.
