Supreme Pharmacist System Chapter 7: Helpless choice

Shi Lei wanted to help, but Zhou Wen refused.

He resolutely drove him away on the grounds that it was inappropriate for him to help with the work he took up.

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

After preparing the gel, start the electrophoresis analysis.

In order to prevent mistakes, he strictly follows the operating procedures for every step, and the operation with ice, temperature, time, and techniques are all excellent, and the eye of true vision is always open to prevent bacterial contamination.

After the electrophoresis machine is turned on, turn around to extract the sample and place it on a glass slide for observation under the electron microscope.

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

Although Zhou Wen already believes that he is not poisoned, he is not afraid of ten thousand, just in case.

He still insisted on doing a blood test for himself. Of course, the results were not unexpected. Whether it was an electron microscope observation or the Eye of True Sight, they were all very healthy.

"verynice~"

Zhou Wen is very happy.

The last bit of grudge in my heart has completely disappeared.

The next step is to extract DNA.

Skilled in dissecting rats, extracting bone marrow, washing, weighting, centrifuging, extracting, all in one go.

And the dose extracted at one time is not 4, but 7, which is far from impossible for ordinary biological production.

Then began to do electron microscope observation.

In fact, in theory, it is no longer necessary to do electron microscope observation, because the Eye of True Sight has seen the successful DNA extraction.

However, the system did not prompt the completion of the task, indicating that this step of electron microscope observation cannot be omitted.

Stain DNA, centrifuge, extract, pipetting, add fixative, centrifuge again, add fixative.

The function of the "fixation solution" is to fix the DNA and prevent the DNA from being decomposed after centrifugation.

Finally, extract the slides and place them on the stage for electron microscope observation.

“perfect~”

When the task completion notification sound came from his ear, Zhou Wen had a happy smile on his face and glanced at the Timer. The whole process took 2 hours, which was really fast. startled.

Just as I was about to open the quest panel, Professor Wang Huiyao, the mentor who has always been in the dark, came in from the door.

Wang Huiyao is in his fifties. He is tall, with a white face and no beard. He wears a suit and tie. 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 others?"

Zhou Wen said: "Shi Lei and Lin Jiayi have just left, and nothing else has come."

Wang Huiyao nodded and said nothing.

It is an open thing that biology has no future. He can understand the students' unwillingness to waste their limited energy in unskilled laboratories, and it is not easy to criticize them.

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

He came to look for Shi Lei. Since Shi Lei was not there, he didn't need to stay any longer.

But at this moment, Wang Huiyao saw the glass slide on the electron microscope stage, pointed his finger and said, "Is this what you detected?"

Zhou Wen nodded, scratched his head and said, "Yes, Professor Wang."

Wang Huiyao did not mention the fact that novices are strictly forbidden to operate the electron microscope, and asked: "How is your study?"

Wang Huiyao also asked casually. Undergraduates like Zhou Wen who have just arrived in the laboratory are already very good at doing electrophoresis analysis well. It is really difficult for them to do electron microscopy observations well.

It's not how difficult the electron microscope observation itself is, but the previous process, such as extraction, staining, centrifugation, etc., each step easily leads to the failure of extraction.

But what Wang Huiyao didn't think about was that Zhou Wen pointed to the 6 DNA strains next to him and said, "I have already learned almost, and these are all observed by electron microscopy."

"Oh?" Wang Huiyao was a little surprised, but also slightly surprised, "You did it all?"

"Yes, Professor Wang."

Wang Huiyao looked around before he remembered 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 quite believe it. He has brought so many undergraduate interns, and few people can do electron microscope observation well at the undergraduate level.

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

After confirming that the electron microscope 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 unknowingly it was already 6:30, "Uh...about 10 hours."

Zhou Wen deliberately extended the time.

Wang Huiyao did not know that the DNA samples of the six strains were extracted from the bone marrow of the same white mouse. In his knowledge, there were at least two groups.

That is, in a smooth case, a group averages 5 hours.

For an undergraduate, it is already very, very good, even excellent.

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

A few seconds later, a slightly surprised look appeared on Wang Huiyao's face.

The structure of DNA on the slide is clearly visible.

Wang Huiyao raised his head, a smile appeared on his face, and praised: "Well done."

Zhou Wen humbly said: "It's all team leader Shi Lei and the others who taught me well."

Wang Huiyao took a serious look at him.

He is quite tall and handsome, especially with the aura between his eyebrows and his feet. He has a confidence that is rarely seen in modern young people.

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

Zhou Wen showed an embarrassed look on his face.

If it is another major, the professor invites him face to face, which is really a big face.

But it's a living creature...

Domestic postgraduates can also do some difficult imitative experiments, and help their supervisors to do some very low-level things, including doctoral students. There will be no independent experiments at all, and postgraduate study is basically a waste of time.

To put it badly, it is the cheap labor of tutors.

This point, although foreign countries are better, but the good ones are limited.

Because this is caused by the biological environment.

Biology is a research science. It is necessary not only to understand all the basic knowledge of biology, but also to understand all the knowledge of the research direction before innovation.

This is really, really, really hard.

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

Although he loves talents, he has not reached the point where he has a hot face to post a cold P-share~IndoMTL.com~ and Zhou Wen also "shush", although embarrassed, but also helpless.

Compared to graduate school, he would prefer to enter a scientific research center or a large laboratory as an experimenter, which would allow him to learn more and allow him to conduct pharmaceutical experiments as soon as possible.

Standing on the spot 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 property page is still there, [Do you want to submit the task immediately? Yes/No]

Select [Yes]

[Ding! mission completed. Now start giving out rewards...Congratulations on getting 200 subject experience points and 300 points. ]

【Would you like to open the box now? Yes/No]

Seeing the words on the prompt box, Zhou Wen became excited again, and whispered in his mouth: "Please God, just give me 1,000 yuan...or anything worth a little money. , I don't choose."

He's so poor he's going to sell his blood.

Now, the price of a horse is expensive. It costs 10 yuan to go out to eat egg fried rice. I don't dare to order takeout because of the delivery fee.

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

With 100,000 points of expectation, Zhou Wen chose [Yes]

A black lacquered wooden textured treasure chest popped out, with intricate patterns engraved on it, and an ancient key still floating beside it.

I meditate in my heart [open]

The key was inserted into the key hole, and the box opened after being rotated, and a spherical object shining crimson emerged.

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

[Congratulations, you have obtained a pure natural pollution-free apple × 10...]
