Gu Qiang changed into a set of snow-white shirts, came to the door of the Peking University Ion Channel Laboratory, lowered his head and sorted out his clothes, and then came to the door, reported his name, and entered the door. Pen, fun, and www.biquge.info

In the laboratory, it was unusually quiet, only the sound of "poof", I don't know where it came from.

Gu Qiang looked around curiously.

Although he used to teach at the University, the University does not have a research institute of the level of the Ion Channel Laboratory.

Especially after knowing that Yang Rui has decided to make G protein-coupled receptors now, Gu Qiang feels even more dignified when he walks in the ion channel laboratory.

He now felt like a soldier of the Hanoi Anti-Smuggling Squad who boarded a battleship for the first time and participated in an ocean-going naval battle. The once unruly seemed to be shocked by the cold air, and became hard and slippery.

"Gu Qiang. Yang Rui saw him and shouted, as happy as the mine owner saw a new mining truck.

"Director Yang......" Gu Qiang shouted.

Yang Rui nodded and said directly: "From today onwards, you will be seconded to the Ion Channel Laboratory of Peking University, is there any problem?"

"This ...... Why did you seconded me here?" Gu Qiang had been hiding this doubt for a long time.

And in his heart, Gu Qiang was silently chanting: Praise me, say you need me!

Yang Rui just raised his eyebrows and said, "I need to speed up our experiments." ”

After speaking, Yang Rui didn't wait for Gu Qiang to continue asking, and then said: "Let me introduce you, Xu Zhengping, is the deputy director of our laboratory, you can ask him first, if you can't find me, the laboratory is managed by Professor Xu." Then, Su Xiankai, Fan Zhenlong and Wang Sisheng ......"

Yang Rui pulled Gu Qiang in front of the other party, pointed at them one by one, and said, "Now Su Xiankai is doing bovine rhodopsin protein, and Fan Zhenlong and Wang Sisheng are doing the purification of various G proteins...... Old Fan, you can explain. ”

Gu Qiang turned his head helplessly, his tense cheeks moved, and some interest slipped, what he wanted was Yang Rui's recognition and appreciation, not Fan Zhenlong's explanation of the same age.

As for things like Yang Rui's younger age, Gu Qiang didn't care much about it anymore.

Maybe he doesn't know much about basic biology, but after the bovine embryo transfer project, his mentality towards Yang Rui is completely different.

Fan Zhenlong couldn't guess Gu Qiang's rich inner life, he stopped what he was doing, looked at Gu Qiang, and said: "We are basically doing repeated tests of several foreign purified protein experiments, on the one hand, to practice, and on the other hand, to prepare for the future." Do you know anything about that?"

"I've done it when it comes to purifying proteins. Gu Qiang glanced at Yang Rui.

Fan Zhenlong looked at Gu Qiang and said, "It's not any protein, it's G protein and G protein-coupled receptors." ”

Perhaps because he felt that he was a little tactful enough, Fan Zhenlong emphasized and said: "Actually, we also started to learn and improve together." ”

"Good ......" Gu Qiang's competitive spirit gradually rose, and he couldn't help but feel a little prickly, and said: "If I finish the work, will I be able to get the first author?"

"Totally impossible. Wang Sisheng glanced at Gu Qiang and said, "In this project, we are in the third echelon, and the names are not necessarily on it." ”

Gu Qiang's eyes flashed, and he said, "I know that the first echelon is what Yang Rui is doing, what is the second echelon?"

"Sequence various G proteins. Yang Rui replied.

Gu Qiangyile: "I know how to sequence proteins. ”

Yang Rui laughed and said, "How many digits of molecular weight?"

Although it only takes twenty or thirty years for humans to sequence hundreds of millions of base pairs at every turn, in the 80s, it was exhausting to sequence an amino acid with a weight of hundreds of molecules.

To put it mildly, in 1986, the laboratory that could sequence an amino acid was already one of the top 30 laboratories in China.

Gu Qiang was only exposed to sequencing in the genetic engineering laboratory, but he also knew how to sequency.

Once it comes to molecular weight, Gu Qiang has nothing to say.

Yang Rui smiled and said, "Let's do it first, don't be anxious, we don't need to rush to solve all the problems now, or set a deadline, do it first and then talk about it." ”

A few people had no choice but to nod their heads, silently returning to the rhythm of continuing the experiment.

Yang Rui opened the unfinished documents and began to read, looking up at other people's work from time to time.

Meat grinders are forced, and in the state of meat grinders, it is much more important to release pressure than to apply pressure.

Gu Qiang changed his white coat and immediately started to operate.

Although there was no welcome party, no meeting and dinner, and even a formal introduction process, Gu Qiang was satisfied enough to be able to go directly to the experimental table.

He has always used his super experimental ability to impress everyone, and when he arrived at the ion channel laboratory, Gu Qiang was still ready to do so.

In fact, Gu Qiang is very fortunate to be able to come to the ion channel laboratory, or in other words, he is very fortunate to be able to follow Yang Rui's footsteps to do scientific research. As a researcher, Gu Qiang knows that his shortcomings are obvious, he has a very good feel, comparable to the field ability of an engineer, and a very strong experimental foundation, but outside the experimental table, Gu Qiang's theoretical ability is difficult to improve.

In the genetic engineering laboratory, Gu Qiang has actually felt the emergence of a bottleneck or ceiling. After the end of the cattle embryo transfer project, Yang Rui left an abundant resource for the genetic engineering laboratory - in the direction of animal husbandry, it can be said that it is the material resources of the top laboratory in China.

However, the laboratory is different from the company, resources must be claimed to play a role, Gu Qiang originally had unique conditions, but the project plan he did was frequently shot by Yang Rui, and it was difficult to pass a project that was suitable for the level of resources......

When Gu Qiang was making a project plan, he also felt his shortcomings. When he was at Shanda, his shortcomings were not particularly obvious, but in the genetic engineering laboratory, the shortcomings were as short as if the Yang Shrinking Gong had been transmitted to Africa, and it was suddenly unusually apparent.

Of course, Gu Qiang can also find someone to cooperate with to do the project like in Shanda, but who can he find to cooperate with Yang Rui?

Gu Qiang knew that the opportunity was rare, so he put all his energy into protein purification.

Compared with his previous protein purification, the difficulty of protein purification of G protein is doubled, as if suddenly moving from planar geometry to solid geometry.

Some people may study for several years and can't turn the corner.

Although, there are always some people who, in just one afternoon, completely change their thinking.

"The dosage of the detergent has been changed so many times, and it can't be purified, so don't take care of the detergent first, determine a similar concentration, and go to the centrifuge first. Gu Qiang's voice suddenly raised, unusually abrupt in the busy and silent laboratory.

Yang Rui couldn't help but raise his head and look over.

Fan Zhenlong and Wang Sisheng seemed to have different opinions, but they were a type of person who was not good at expressing themselves, and they immediately hesitated when they received the sudden attention of everyone.

Gu Qiang immediately made a decision, snatched the command, and said: "Regardless of whether the centrifuge can make a result, you can see the difference after doing it once, and then decide what to do." ”

After speaking, Gu Qiang moved on his own.

His operation was extremely fast, and he finished the steps that others would take half an hour to figure out in a while, and when the ultracentrifuge was spinning, Fan Zhenlong and Wang Sisheng each wrote and drew on the paper.

Yang Rui walked over curiously to take a look, and saw Fan Zhenlong and Wang Sisheng each writing their own calculations, one used chemical ideas, and the other used physical ideas, and they all looked like they all had some truth.

For a moment, Yang Rui only felt that his eyes were tingling.

The light of the top student is too strong, and people don't want to look at it directly.

Although Yang Rui can say that everyone accepts different education systems, the age of Fan Zhenlong and Wang Sisheng determines that most of their time is based on theoretical calculations, while later generations of students pay more attention to experimental education.

However, Yang Rui also knew in his heart that if he wanted to let himself learn the theoretical calculation of this model, his head really had to be blown up.

Moreover, even in terms of experimental verification, his talent is also inferior to Gu Qiang.

"Director Yang?" Fan Zhenlong couldn't help but feel a little apprehensive when he saw Yang Rui staring at his calculations.

Yang Rui woke up from his trance suddenly, smiled, and said, "I'll take a look at it casually." ”

"Oh......" Fan Zhenlong responded hesitantly, and then looked at Yang Rui's expression, but explained unconfidently: "I want to check the groups of experiments I did just now to see what the data difference is, in addition, I think that direct centrifugation, the effect may not be there, so it is a bit of a waste of consumables." ”

"Well, it's better to leave it in the refrigerator for two hours before centrifugation, and in addition, if you do it again with saturated ammonia sulfate, the result may be clearer. Yang Rui was still in a state of shock, and naturally said a plan, but it was the G protein purification plan he had thought about before.

Fan Zhenlong was stunned when he heard this, and Gu Qiang in front of him was already slapping his head heavily, and watched a nest of test tubes spin wildly in the centrifuge with regret.

"I just said don't rush yet. Wang Sisheng also came back to his senses, rubbed the information in his hand, and said: "It is a good way to treat it with saturated ammonium sulfate, so that as soon as you do it, the precipitated ones will be precipitated, and the precipitated ones will be dissolved and precipitated a few times, and the effect of running out will be much better." ”

Gu Qiang had the heart to refute, but he couldn't refute anything, the corners of his eyes twitched a few times, and he obediently walked back and said: "Then do another set of experiments according to this plan, and let it turn if it is centrifuging." ”

When Gu Qiang spoke, he deliberately avoided Yang Rui's gaze, like a little girl who avoided being sunburned by the scorching sun.
