Shi Lei wanted to help, but was rejected by Zhou Wen.

He resolutely drove him away on the grounds that it was inappropriate for him to help with his own work.

Shi Lei is here, and he can't show his hands and feet.

After the gel is prepared, the electrophoresis analysis begins.

In order to prevent mistakes, he strictly follows the operating procedures at every step, operates with ice, and strives for perfection in temperature, time, and techniques, while the True Eye is always open to prevent bacterial contamination.

After the electrophoresis machine is turned on, turn back to extract the sample and place it on a glass slide, and observe it on the electron microscope.

After observation, no suspicious virus was found in the sample tissues of the mutant aphids.

Although Zhou Wen already believed that he was not poisoned, he was not afraid of 10,000, just in case.

He still insisted on doing a blood test for himself, and the results were of course not unexpected, whether it was electron microscopy observation or true vision, he was very healthy.

“very nice~“

Zhou Wen was very happy.

The last bit of mustard in my heart is completely gone.

Next, the DNA extraction begins.

Skillfully dissect mice, extract bone marrow, rinse, counterweight, centrifugation, extraction, all in one go.

Moreover, the dose extracted at one time is not 4 strains, but 7 strains, which is far from being possible for this general biological life.

Next, we will start with electron microscopy.

In fact, theoretically, there is no need to do electron microscopy observation, because the True Eye has already seen the success of DNA extraction.

However, the system did not prompt the task to be completed, indicating that the step of electron microscopy observation could not be omitted.

DNA staining, centrifugation, extraction, pipetting, fixative, centrifugation, and fixative.

The purpose of the "fixative solution" is to fix the DNA and prevent the DNA from being broken down after centrifugation.

Finally, the slide is extracted and placed on the stage for electron microscope observation.

“perfect~”

When there was a prompt in his ears to complete the task, Zhou Wen showed a happy smile on his face, and glanced at Timer, the whole process took 2 hours, which is simply fast, if Shi Lei and they knew, it is estimated that their eyes would be shocked.

Just as he was about to open the task panel, Professor Wang Huiyao, the mentor who had always seen the dragon and never saw the end, came in from the door.

Wang Huiyao is in his fifties, tall, white-faced, wearing a suit and tie, and people who don't know him think he is a business elite.

Seeing that Zhou Wen was alone in the laboratory, Wang Huiyao said strangely: "Why are you alone, and there are still people?"

Zhou Wen said: "Shi Lei and Lin Jiayi just left, and nothing else came. ”

Wang Huiyao nodded and didn't say anything more.

The lack of future in biology is a public matter, and he can understand the feeling that students are unwilling to waste their limited energy in a laboratory without technical content, and it is not easy to criticize anything.

His eyes wandered around the lab, and then he prepared to leave.

He came to find Shi Lei, and since Shi Lei was not there, there was no need for him to continue to stay.

But at this moment, Wang Huiyao saw the slide on the electron microscope stage, stretched out his finger and said, "This is what you tested?"

Zhou Wen nodded, scratched his head and said, "Well, yes, Professor Wang." ”

Wang Huiyao didn't mention that novices are strictly forbidden to operate the electron microscope, and asked, "How are you learning?"

Wang Huiyao also asked casually, an undergraduate like Zhou Wen, who has just come to the laboratory, can do a good job of electrophoresis analysis, and it is really difficult to expect them to do a good job of electron microscopy observation.

It's not that the EM observation itself is difficult, but that the previous processes, such as extraction, staining, centrifugation, etc., are easy to lead to extraction failures at every step.

However, what Wang Huiyao didn't expect was that Zhou Wen actually pointed to the 6 DNA strains next to him and said, "I've learned almost, these are all observed by electron microscopy." ”

"Oh?" Wang Huiyao was a little surprised, and at the same time slightly surprised, "You did it?"

"Well, yes, Professor Wang. ”

Wang Huiyao looked left and right before remembering that Shi Lei and the others were not in the laboratory, "Your name is ...... Zhou Wen, right?"

"Hmm. ”

Wang Huiyao nodded slightly, but he still didn't believe it, he had brought so many undergraduate interns, and few of them could do a good job of electron microscopy observation at the undergraduate level.

He walked over to the electron microscope and looked at it first.

After making sure the EM was not damaged, he looked at the slide on the stage and asked, "How long did it take?"

Zhou Wen glanced at the wall clock, and before he knew it, it was already half past six, "Uh...... About 10 hours. ”

Zhou Wen deliberately said that the time was long.

Wang Huiyao didn't know that the six DNA samples were extracted from the bone marrow of the same white rat, and in his cognition, there were at least two or more groups.

That is, in a smooth situation, a set of an average of 5 hours.

For an undergraduate, it's already very, very good, and even excellent.

Wang Huiyao sat down in front of the electron microscope, adjusted the lens and began to observe.

After a few seconds, Wang Huiyao showed a slightly surprised look on his face.

The structure of the DNA on the slide is clearly visible.

Wang Huiyao raised his head, a smile appeared on his face, and praised: "Good job." ”

Zhou Wen said modestly: "It's all Shi Lei, the leader of the group, who taught them well." ”

Wang Huiyao looked at him seriously.

He is quite tall, and he looks quite handsome, especially the momentum between his eyebrows, special feet, and a confidence that is rare in modern young people.

Wang Huiyao stood up and patted him on the shoulder, and asked with a smile, "I remember that you haven't taken the graduate school entrance examination yet." How about it, are you interested in applying for my graduate school?"

Zhou Wen had an embarrassed look on his face.

If it is another major, the professor invites it in person, which is really a big face.

But what about creatures......

Domestic graduate students can also do some difficult imitative experiments and help their supervisors do some very low things, including doctoral students, there will be no independent experiments at all, and graduate school is basically a waste of time.

To put it mildly, it is the cheap labor of the mentor.

Although this point is a little better abroad, the good ones are limited.

Because it's caused by the biological environment.

Biology is a research science, and it is necessary not only to understand all the basic knowledge of the current biology discipline, but also to understand all the knowledge of the research direction, and then to innovate.

It's just too hard, it's too hard.

Seeing the expression on Zhou Wen's face, Wang Huiyao understood what he meant, didn't say anything, and after removing the smile on his face, he nodded and left.

Although he loves talent, he has not reached the point of sticking a cold P share with a hot face.

And Zhou Wen also "shh

Compared with graduate school, he would prefer to work as an experimenter in a scientific research center or a large laboratory, so that he can learn more things and allow him to conduct pharmaceutical experiments as soon as possible.

Standing in place and thinking about the next development for a while, Zhou Wen thought of the task and immediately called out the system.

The prompt box on the properties page is still there, [Do you want to submit the task immediately?Yes/No]

Select Yes

【Ding!Mission accomplished.】 Rewards are now available...... Congratulations on earning 200 points of subject experience and 300 points. 】

[Is it unboxing now?Yes/No]

Seeing the words on the prompt box, Zhou Wen became excited again, and muttered in his mouth: "Please, God, just give me a 1,000 yuan...... Or anything of value, I don't pick it. ”

He's so poor that he's about to sell blood.

Now the price of a horse is expensive, and it costs 10 yuan to go out and eat egg fried rice casually, and I don't dare to call for takeaway, because of the delivery fee.

He didn't dare to look at the fruit or anything, he was afraid that he would shed poor tears.

With 100,000 expectations, Zhou Wen chose [Yes]

A black, wooden-textured treasure chest popped up, with intricate patterns carved on it, and an ancient key still hovering next to it.

Recite silently in your heart [Open]

The key was inserted into the keyhole, and when it was rotated, the chest opened, revealing a spherical object glowing crimson.

Before he could see what it was, a prompt popped up, just like last night.

[Congratulations, get a natural and pollution-free apple ×10......]
