I reach the pinnacle of life by learning

As expected, a new task popped up in the system.

[System task] Prove that the conclusion of myocardial stem cells is falsified.Reward: A 300 kV cryo-electron microscope.

Cryo-electron microscope is a good thing, its full name is cryo-electron microscope.

Anyone who has attended junior high school biology will know that microscopes are used to observe microorganisms.

The microscope we talk about now usually refers to an optical microscope, which can be used to observe cells, but it is powerless to observe smaller biological structures.

The cryo-electron microscope is more awesome, and the awesomeness is that it can directly take pictures of protein molecules.

Ashamed to say, due to technical reasons, the traditional biomolecular structure diagrams are actually hand-drawn by scientists.

The cryo-electron microscope saves them from having to work hard to predict the conformation of proteins. Just look at them with a cryo-electron microscope, and they can know the relatively real structure of proteins and even protein complexes. It is definitely a magic weapon for biological research.

In biological research, you are 1 minute slower, and the honors and patents belong to others.

Cryo-electron microscopy is in the professional field, and I don’t know how many minutes it can save scientific research dogs.

According to the timeline, the cryo-electron microscope should have been invented two years ago.

In 2017, the three inventors of the cryo-electron microscope shared the Nobel Prize in Chemistry.

In 2020, the price of a cryo-electron microscope will range from 500 million to 4000 million depending on the kilovolt. It will only be sold more expensive in 2015, and it is a good thing that is priceless in the market.

Professor Shi of Tsinghua University next door, because there are three cryo-electron microscopes in the laboratory, Yan Daye, who is so angry, works hard to learn and kills the villain in the middle of the night.Tsinghua University also relied on the cryo-electron microscope to let the scientific research dog of biological structure produce many papers with high impact factors.

With Qiao Yu coming to Yanjing to go to university, it was time for the laboratory of Xun'an Biopharmaceutical Company to open a semicolon in the capital.

What's more, it is impossible for Qiao Yu to work in someone else's laboratory all the time.

He definitely needs a laboratory to complete Professor Sheng's homework and conduct research he is interested in. The systematic move is undoubtedly a timely help.

The 300kv cryo-electron microscope should be the acme of what Bluestar can do at the cutting-edge technology level.

"You are quite generous this time." Qiao Yu praised the system.

System: "You're welcome. A good host is really good. Your success is my eternal pursuit."

The two top cancers are very congenial and cherish each other on the road to becoming stronger.

System: "However, I have to remind the host that men will only affect the speed at which you draw your sword."

Yes.

Just a week ago, Song Tianyu committed a murder with alcohol and confessed his love crying.

Qiao Yu agreed.

The system saw it in its eyes and was anxious in its heart. It called Song Tianyu, an expert in straight balls, and made a precise blow to Qiao Yu's fatherly aura.After all, pity is also love, which father is willing to let his son cry all the time?

The system stared at Ma Guanghui, Chu Xining, and the newcomer Qun Chengguang, except him.

Well, you Song Tianyu, looking at someone with thick eyebrows and big eyes, you are so scheming!

Qiao Yu thought for a moment, then replied: "15 minutes a day, it won't affect much."

Before, my roommate was still wondering why he went back to the dormitory 15 minutes earlier every day. The reason was that he allocated 15 minutes of the day to Song Tianyu.

As a boyfriend, this is what he should do.

The system decided not to speak anymore, so as not to look like an evil mother-in-law who beats mandarin ducks.

On the first day of the National Day, Qiao Yu arrived at Professor Sun Rui's laboratory on time to report.

They only had professor Sun's class in their sophomore year, so this was the first time Qiao Yu saw him.

serious.It was Qiao Yu's first impression of this professor.

"You are Qiao Yu, right? Did you bring your school card? I'll give you access to the laboratory first."

Sun Rui is close to 50 years old this year, with deep frown lines between his brows, and the corners of his mouth are naturally turned down when he is not smiling.It doesn't look easy to get along with.

Qiao Yu respectfully said: "It's me, Professor Sun. I brought it."

In fact, Sun Rui was somewhat dissatisfied with Ye Qinxue's coming in.

There are now two academicians in the Yanda Academy of Biological Sciences, one is Ye Qinxue and the other is Li Dongwei.

When the two academicians dissed the Tsinghua University next door, they were naturally as close as brothers; but when they were in the same school, even if the research directions were different, how could they not take the lead and talk about it.

A well-known foreign university holds an international conference in the field of biology and invites Yanda. Who will go?

The principal allocates a small goal to the Academy of Life Sciences as research funding, who has more and who has less?Even if academicians do not lack funds, but there are so many professors and senior engineers who follow you around, you should think about them, right?

……

There are so many different things.

Unfortunately, Professor Sun Rui is with Academician Li.It's just that now that Academician Ye is in the limelight, with old qualifications and great power to speak, it's hard for him to reject Qiao Yu explicitly.

Academician Ye also had his own considerations for letting Qiao Yu go.

First, Professor Sun is more objective and will not act emotionally. He is an "experimental" professor rather than a "thesis-type" professor. You will definitely learn something from him.

Second, because Professor Sun is close to Academician Li, he will definitely not be too enthusiastic.If Qiao Yu can get good grades under Professor Sun, it will be enough to prove his true talent and learning.

Third, it doesn't matter even if Qiao Yu is excluded in Sun Rui's biology laboratory.At that time, he can be transferred to the laboratory under his own name, so that he can feel what it means to be warm like spring.Comparing the two, I'm not afraid that Qiao Yu won't be grateful to him.

Fourth, in the entire school, only Sun Rui's Provincial Key Laboratory of Cardiac Stem Cells met Qiao Yu's requirements.

If it is Tsinghua University, there are more medical students there.It should give Qiao Yu more choices.

When Qiao Yu was looking at Sun Rui, the other party was also looking at him.

The young man is very energetic, with bright eyes and attractive.There are several single female researchers in the lab. If it's not the wrong age, I can introduce you... Wait, isn't he here to criticize?

Professor Sun coughed: "Academician Ye said that you already have a certain scientific research foundation, and when you enter the laboratory later, I will ask your senior to take you for a while to familiarize yourself with the workflow of our laboratory."

This is the only way for every newcomer to scientific research. After all, every laboratory has its own core secrets. What should I do if I let newcomers get in touch with it from the very beginning, and then change jobs?Contracts and laws only govern those who abide by them.

Qiao Yu nodded in agreement.

He Shuhuan is the Sri Lankan in "Heaven will send a great mission to Sri Lankan people".

He was doing the c-kit positive cardiac stem cell migration experiment on the laboratory bench, and then he was patted on the shoulder by the leader of the scientific research team.

"A freshman is coming to the laboratory recently, you go and bring it." Xiao Zu said long, "It's the boss's order."

He Shuhuan couldn't help but groan, lamenting that his chance had finally come.

He has been in the laboratory for half a year, and his daily tasks are nothing more than raising cells, preparing buffers, washing bottles, occasionally helping to record experimental data, or running around the school's finance department.

But this is also something that can't be helped, after all, he is a newcomer.He Shuhuan felt excited when he thought that a newer researcher would take over his job in the future, and he, a graduate student, would be able to make a big difference in other more advanced fields.

The only question is, how come a freshman here?

It's just that when Qiao Yu appeared in front of him, He Shuhuan was in a trance, and a familiar line appeared in his mind: I seem to have seen this brother somewhere...

Qiao Yu was very polite: "Hello senior."

He Shuhuan patted his thigh: "You are that, brother, Goldbach?!"

It was just broadcast on the news network a few days ago.Qiao Yu's name is now very popular in Yan University.

The study department of the student union next door was eagerly waiting for Qiao Yu to apply for the job, but he couldn't help being disappointed when he didn't find anyone after the new recruiting season ended.

Qiao Yu: "Goldbach's conjecture was notarized by my grandfather. My name is Qiao Yu."

"Okay, follow me to familiarize yourself with the basic operations these few days." He Shuhuan regained his composure, "Add a WeChat first, and then I will drag you into the laboratory group."

Qiao Yu followed suit.

It can be felt that most of the researchers under Professor Sun are as serious and rigid as him.Everyone didn't express much welcome to the new colleagues' entry, maybe because they thought Qiao Yu came here to brush up their resumes, so that they could look good when applying for studying abroad in the future.

He Shuhuan pulled Qiao Yu to the experimental bench: "Today I will teach you how to raise cells first."

The official name of cultured cells is called cell culture technology. By cultivating cells to obtain a large number of cells or metabolites, it is the core and most basic technology in biological research.

Regarding the matter of raising cells, Qiao Yu has raised cells in his own laboratory in the past, not a thousand times, but also [-] times.

Cells are delicate and expensive to feed, and the project team leader would frown if there were too many losses.Because not only wasting money, but also delaying the progress of the experiment.

Standing beside Qiao Yu, He Shuhuan talked eloquently: "Different cells require different culture media. We are raising c-kit positive cardiac stem cells and cardiomyocytes. We need RPMI-1640 culture medium with a concentration of [-]%. Fetal bovine serum..."

"Myocardial stem cells are a hot topic at present, and they are also the gospel to solve cardiovascular diseases. According to Dr. Ansavi's research, c-kit positive cells can regenerate heart muscle and make heart muscle cells self-repair. This experiment has been performed in many breastfeeding Proven in animals. The future holds great promise."

After showing off his crisp voice, he turned his head, ready to receive a wave of admiring gazes from Qiao Yu, but in the blink of an eye, he saw that Qiao Yu had already held up the transfection reagent.

He Shuhuan was a little dumbfounded: "Wait, this is the last step."

"finished."

Qiao Yu calmly put down the dropper.

How can it be? !He just prepared the culture medium here!

He Shuhuan walked over in disbelief, and looked under the microscope, confirming the survival of the cardiomyocytes.The shape is perfect enough to be included in a textbook.

"Very good, you are very skilled in operation..." His mouth was a little dry, and he praised it.

Qiao Yu's face was paralyzed as always: "Practice makes perfect."

"Oh, have you been to the laboratory before?" He Shuhuan asked with an idea.

"When I was in high school, I was the project leader of No. 1 Laboratory of Xun'an Biopharmaceutical Company. I have published as a first author in many foreign journals such as "Cell and Molecular Biology", "Blood", "New Advances in Cytochemistry" and so on. 11 papers..." Qiao Yu took out his own small paper from his bag, "This is the one I am quite satisfied with, the title is translated as "The Application of Gene Regulatory Network Reconstruction Interleukin-1 in Chronic Lymphoid Leukocytes" ", senior, you can just look at it casually."

He Shuhuan was holding the paper, and Qiao Yu in front of him suddenly became unattainable.

He had a premonition that even if Qiao Yu came, but he was in charge of brushing bottles in the laboratory, he might still continue...

The author has something to say: Reader: Didn’t you say to write more today?

Author: Yes, I wrote 7000 words today, but the team leader temporarily gave me a task to shoot a video, so I decided to put the remaining 4000 words in the manuscript box, and use it as tomorrow's update...

2020.6.8: Fixed a bug.As mentioned before, another academician of the Academy of Biological Sciences was surnamed Li, so Academician Qin Dongwei changed his name to Academician Li Dongwei.
