"Where did you fail?" Yang Rui was not very nervous, just stunned for a moment, and then continued to brush his teeth. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Gu Qiang looked ashamed and said, "The dissociation or purification is not clean, and the image is gray." ”

As he spoke, Gu Qiang rubbed his hair vigorously and said, "I've purified it countless times, but I didn't expect it to go wrong this time." ”

"Are the steps before purification correct?" Yang Rui asked with foam in his mouth.

"It should be fine, I've checked before. "Periodic inspection is a necessary means, otherwise, if you find out that the pre-experiment has collapsed later, the experimenter himself will have to collapse.

Yang Rui nodded and said, "In that case, first of all, you check yourself and see where the mistake is." ”

Gu Qiang bowed his head and said "En".

"Secondly, I will form another team to help you do the examination, mainly check the experimental records, and compare them with your previous experiments to see if there are any differences. Yang Rui said very atmosphericly, which means that the scale of his laboratory is large, otherwise, the existing three duplicate groups can support ordinary scientific research laboratories.

Gu Qiang still kept his head down, and this time he didn't say anything.

"Third. Yang Rui continued: "The speed on your side should be a little faster, after the inspection, no matter what the conclusion is, make another set of repetitions." Didn't I ask you to protect your lab table before? The consumables are also recorded, you can compare them to see if the changes in the consumables have caused the difference in the experimental results......

What Yang Rui said was extremely systematic and simple.

In the final analysis, it is a sentence, compared with the old foundation left behind.

This is the similarity and difference brought about by the systematic scientific research experience, Gu Qiang is a semi-wild researcher who has joined the laboratory since graduating from the bachelor's degree, and he used to think that Yang Rui's requirements were cumbersome, but he only discovered the importance at this moment.

If the first and second points are still a little doubtful for Gu Qiang, the third point that Yang Rui said more or less boosted Gu Qiang's mood.

However, Gu Qiang was still a little uneasy and said: "There are so many things in the laboratory, and you usually can't make mistakes." ”

"There are so many things that can go wrong, maybe there is a bottle of medicine that has been released for too long and decomposes in the sun. Yang Rui casually said an example.

In the laboratory, all the brown bottles and black bottles are designed to resist the sun, and the reagents that can be decomposed by ultraviolet rays are much more than people think, and the solvents that are now prepared in the laboratory are even more so.

The same principle is also used in bagged braised chicken thighs, if you pay attention to it, the braised chicken thigh bags are opaque. In fact, for the purpose of sales, it is the most effective publicity to let consumers see the food inside directly through the packaging bag, however, due to the decomposition of sunlight, the beautiful marinated color of the braised chicken thighs will become miserable and white after a few days of exposure, which makes people lose their appetite.

There are so many error-prone parts in the lab, especially in a long series, and it is even more difficult to do it all at once. Because of this, Yang Rui felt that Gu Qiang's strong luck was unbelievable.

The first time there was no repeat success, in Yang Rui's opinion, it is normal.

Gu Qiang wrinkled his brows, waited for Yang Rui to rinse his mouth, washed his face, and came out of the bathroom, before he followed closely and said, "The problem is, when I do the repeated test, I pay attention to it, I'm worried about ......"

"Nothing to worry about. Yang Rui stopped, turned to look at Gu Qiang, and asked, "The crystal structure has been released, this is the undoubted evidence." Repeat the experiment, but I hope to be cautious, otherwise, in order to change to other labs, in order to rush for time, I may have sent out the article now. So, the experiment you do will definitely be repeatable, we just need to find out what the problem is. ”

The crystal structure of G protein-coupled receptors has not been seen before.

It's like an image of a rare creature, and it's imaged with an instrument at once, and it's evidence that iron can no longer be iron.

Gu Qiang silently bowed his head, raised his head again, and whispered: "You're not afraid that my experiment will be fake?"

Yang Rui glanced at him strangely and said, "How could it be an experiment fraud." ”

"Do you believe me?" Gu Qiang was suddenly a little excited.

"Of course I trust you. Yang Rui frowned: "What are you worried about?" ”

Gu Qiang only felt a pang in his chest, and he was speechless.

"Did anyone say anything?" asked Yang Rui.

Gu Qiang nodded lightly and said, "I heard some gossip, it's nothing." ”

With that, he rushed into the bathroom, turned on the faucet, washed his face well, blew his nose while washing, and when he came out after a while, he wiped his face with paper and said, "It's okay, I'm just afraid of messing up." ”

"If you make it, you make it, be confident. Yang Rui patted Gu Qiang's shoulder and said, "Okay, don't think about it, check two more rounds, and repeat the experiment, how difficult it can be." ”

Gu Qiang clenched his teeth, nodded vigorously, and said, "I will definitely do it." ”

"Well, go ahead. ”

Yang Rui was still in a state where he had just woken up, and he didn't think too much.

He actually forgot that although he knew the crystal structure of the G protein-coupled receptor made by Gu Qiang, others did not. Even Gu Qiang is not sure whether what he has made is the crystal structure of the real G protein-coupled receptor. The second stage is just beginning, and everyone's knowledge is not complete.

Even because the scheme given by Yang Rui is too one-step, everyone's guess about the crystal structure of G protein-coupled receptors is not very complete.

Theoretically, Gu Qiang can make the crystal structure of any compound and regard it as the crystal structure of G protein-coupled receptors.

Of course, this kind of fraud is very low-level fraud, but several of the scientific research frauds exposed in history are high-level. For example, there is a laboratory in the United States that makes AIDS vaccines, and when they are injected into rabbits, they actually produce antibodies, which simply stunned the pharmaceutical community back then, and the results have never been repeated, so they have to admit that they are fraudulent. This is a typical mentally handicapped fraud, which cannot be repeated as a matter of course, so if it can be repeated, it will not be equivalent to the success of the vaccine, and it is not called fraud.

In the ion channel laboratory, there are researchers who are familiar with Gu Qiang, and there are assistants who are not familiar with Gu Qiang, and in the case of incomplete information, it is inevitable to question Gu Qiang.

In fact, if you look at the schedule on the white wall, you will feel that it is correct to question - the progress of the top foreign laboratories is not even 10%, and Gu Qiang actually implemented Yang Rui's plan in one go, which can be described as extremely unreasonable.

After the initial admiration and shock, everyone's skepticism followed.

When Gu Qiang was busy for a day and a night, but announced that he had failed to repeat himself, suspicion inevitably revealed some sharp corners.

Even Gu Qiang can't help but doubt himself: Am I mistaken? Am I wrong? Am I coming to a plausible result by mistake?

Back in the laboratory, Gu Qiang held his breath and started a new round of repeated experiments by himself, but his appearance was far less calm than his inner peace.

Yikes!

Horse's!

This time, without waiting for the evening, Gu Qiang failed again.

Yang Rui heard the voice, came to Gu Qiang's experimental table to take a look, and asked, "Operation error?"

"Yes. Gu Qiang was extremely annoyed.

"So, let's analyze your last round of experiments. Yang Rui said by name: "Professor Man Hai, Professor Tao Xuelin, you are more experienced, well, add another Wu Qi, come here, let's help Gu Qiang analyze together." ”

Man Hai was obviously a little unhappy and asked, "How do you want to analyze it?"

"Analyze everything from beginning to end to see the difference between successful and failed experiments. Yang Rui replied.

Man Hai was surprised: "It's going to take a lot of time." ”

"Maybe. ”

"We ...... Don't you want to bet all the treasures here?" Man Hai couldn't help but hesitate, he was not familiar with Gu Qiang, so he was not willing to spend all his precious time here. If it turns out that Gu Qiang's experiment is problematic, the time taken to fully analyze it may lead the ion channel laboratory to the abyss of failure.

Yang Rui scoffed at this and said, "If you can't repeat it twice, you have to find your own way? I'll give you two years, can you make a result?" Is the plank road so easy to walk?"

What he said was extremely polite, and it could even be said that he had a somewhat critical tone, as a professor at Peking University, Man Hai was suddenly flushed by Yang Ruixun.

And Gu Qiang, who was next to him, also blushed his cheeks.

For him, Yang Rui's affirmation at this time can be described as nectar.

"That, comprehensive analysis, is it to find out all the differences?" Wu Qi cautiously raised his hand, and by the way, he parted from the somewhat solemn atmosphere.

Yang Rui turned his head and said, "That's right, all the differences must be marked." ”

Repeated experiments are not easy experiments, and students who can't do experiments according to books should feel more about it.

"I've seen one before, and I don't know if it counts. Wu Qi looked at Yang Rui and then at Gu Qiang.

Yang Rui said with a pleasant face: "You say." ”

Wu Qi swallowed a mouthful of saliva and said, "I read Researcher Gu's experimental records, the isoamyl alcohol he used to make the buffer for the first time was taken from cabinet 3, and the isoamyl alcohol for the second buffer was taken from cabinet 4. ”

"What's the difference? It's the same company's product. Gu Qiang originally had some expectations, but at the moment he felt bored.

His own laboratory table is relatively close to cabinet 3, but after changing the table, it is closer to cabinet 4, and he feels that there is no need to take the reagents in a special position.

Wu Qi was a little nervous, and said: "Although it is from the same company, I don't know if it counts, the isoamyl alcohol in cabinet 4 was sent last month, and it was specially put here for us to practice." ”

Gu Qiang's face changed suddenly: "Why don't you mark it?"

Wu Qi whispered: "It's no problem when we use it, but I don't know if it affects the experiment on your side." ”

"I'll do it again. Gu Qiang didn't go to fight with Wu Qi, unfolded the experimental table, and started to operate.

The interest of everyone dispersed, but the topic was still focused on Gu Qiang and his experiments.
