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.
Shi Lei is here, he can’t do anything.
After preparing the gel, start electrophoresis analysis.
In order to prevent mistakes, he strictly follows the operating procedures at every step. The operation with ice, temperature, time, and technique are all refined. At the same time, the Eye of True Vision is always open to prevent bacterial contamination.
After the electrophoresis machine is turned on, turn back to extract the sample and place it on the glass slide, and observe it under the electron microscope.
After observation, no suspicious virus was found in the sample tissue of the mutant aphids.
Although Zhou Wen already believed that he was not poisoned, he was not afraid of ten thousand, just in case.
He still insisted on doing a blood test for himself, and the results were of course not surprising. Whether it was the electron microscope observation or the true vision, he was very healthy.
“verynice~”
Zhou Wen is very happy.
The last bit of grudge in his heart also disappeared completely.
Next, DNA extraction will begin.
Proficiently dissecting white mice, extracting bone marrow, washing, weighting, centrifuging, extracting, all in one go.
And the dose of one extraction is not 4 plants, but 7 plants. This general biological growth is far from possible.
Then I started to do electron microscope observation.
In fact, theoretically, there is no need to perform electron microscopic observation, because the true eye has already seen the successful DNA extraction.
However, the system did not prompt the task to be completed, indicating that the electron microscope observation step cannot be omitted.
Stain, centrifuge, extract, pipette, add fixative to DNA, centrifuge again, and add fixative.
The function of the “fixing solution” is to fix the DNA and prevent the DNA from being decomposed after centrifugation.
Finally, the slides were drawn and placed on the stage for electron microscope observation.
“perfect~”
When the task completion reminder heard in his ear, Zhou Wen showed a happy smile on his face. He glanced at the Timer. The whole process took 2 hours, which was extremely fast. If Shi Lei and the others knew it, they would be surprised.
Just about to open the task panel, Professor Wang Huiyao, the mentor who has always seen the dragon and missed the end, came in from the door.
Wang Huiyao is in his fifties. He is tall and white. He wears a suit and tie. People who don’t know him think he is a business elite.
Seeing Zhou Wen alone in the laboratory, Wang Huiyao said strangely: “Why are you alone? Are there anyone else?”
Zhou Wen said: “Shi Lei and Lin Jiayi have just left, but nothing else came.”
Wang Huiyao nodded without saying much.
The fact that biology has no future is an open matter. The students’ feeling that they are unwilling to waste their limited energy in a laboratory with no technical content can understand it, and it is hard to criticize anything.
looked around in the laboratory, and then he was about to leave.
He came to look for Shi Lei, and since Shi Lei is not there, he has no need to stay.
But at this moment, Wang Huiyao saw the glass slide on the electron microscope stage, pointed his finger and said, “This is what you inspected?”
Zhou Wen nodded, scratched his head and said, “Yes, Professor Wang.”
Wang Huiyao did not mention that novices are strictly prohibited from operating the electron microscope, and asked: “How are you learning?”
Wang Huiyao also asked casually that undergraduates like Zhou Wen who have just arrived in the laboratory are already very good to be able to do a good job in electrophoresis analysis. It is really difficult to expect them to do well in electron microscope observation.
is not how difficult it is to observe the electron microscope itself, but mainly because of the previous procedures, such as extraction, staining, centrifugation, etc., each step easily leads to extraction failure.
But what Wang Huiyao didn’t think about was that Zhou Wen actually pointed to the six DNA strains next to him and said, “I have learned almost all of them. These have been observed by electron microscopes.”
“Oh?” Wang Huiyao was a little surprised, but also slightly surprised, “You did it?”
“Yes, Professor Wang.”
Wang Huiyao looked around before remembering that Shi Lei and none of them were in the laboratory. “Your name is… Zhou Wen, right?”
“Ok.”
Wang Huiyao nodded slightly, but he was still not convinced that he had brought so many undergraduate interns, and few of them could do the electron microscope observation well at the undergraduate level.
He walked to the side of the electron microscope and looked at the electron microscope first.
After confirming that the electron microscope was not damaged, he looked at the glass slide on the stage and asked, “How long did it take?”
Zhou Wen glanced at the wall clock, unknowingly it was already 6:30, “Uh…about 10 hours.”
Zhou Wen deliberately said the time was long.
Wang Huiyao didn’t know that the 6 DNA samples were extracted from the bone marrow of the same white mouse. In his knowledge, there are at least two or more DNA samples.
In other words, in a smooth situation, a group averages 5 hours.
For an undergraduate, it is very, very good, even excellent.
Wang Huiyao sat down in front of the electron microscope, adjusted the lens and started to observe.
A few seconds later, Wang Huiyao showed a slightly surprised look on his face.
The DNA structure on the slide is clearly visible.
Wang Huiyao raised his head, with a smile on his face, and praised: “Good job.”
Zhou Wen modestly said: “It’s all Team Leader Shi Lei who taught well.”
Wang Huiyao looked at him seriously.
is quite tall and looks quite handsome, especially the aura between the eyebrows, special feet, and a kind of self-confidence rarely seen in modern young people.
Wang Huiyao stood up and patted him on the shoulder, and said with a smile: “I remember you haven’t entered the postgraduate entrance exam. How about it, are you interested in applying for my graduate student?”
Zhou Wen showed an awkward look on his face.
If it’s another major, the professor invites it in person, it’s really a big face.
But a creature…
Domestic graduate students can also do some relatively difficult imitation 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.
The ugly thing is the cheap labor of the tutor.
Although it’s better abroad, it’s limited.
Because this is caused by the biological environment.
Biology is a research science. It is not only necessary to understand all the basic knowledge of biology, but also to understand all the knowledge of the research direction before innovation.
This is too difficult, too difficult.
Seeing the expression on Zhou Wen’s face, Wang Huiyao understood what he meant and didn’t say anything. After suppressing the smile on his face, he nodded and left.
Although he loves talents, he hasn’t gotten to the point of putting on cold P shares with a hot face. UU reading www.uukａnshu.com
And Zhou Wen also “hush”, although embarrassing, but also helpless.
Compared to graduate school, he prefers to enter a scientific research center or a large laboratory as an experimenter, so that he can learn more and allow him to conduct pharmaceutical experiments as soon as possible.
Standing still 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, [May I ask whether to submit the task immediately? whether】
Select【Yes】
【Ding! mission completed. Now start to issue rewards… Congratulations on getting 200 subject experience and 300 points. 】
【May I open the box now? whether】
Seeing the words on the prompt box, Zhou Wen got excited again, and muttered: “God please, just give me 1,000 yuan… or anything worth a little bit of money will do, I don’t Picked.”
He is really poor and almost selling blood.
Nowadays, the price is expensive. It costs 10 yuan to eat an egg fried rice when you go out. I don’t dare to order takeout because of the delivery fee.
He didn’t even dare to look at fruits or anything. He was afraid he would shed poor tears.
With one hundred thousand hopes, Zhou Wen chose [Yes]
The black lacquered wooden texture treasure chest popped out, with complicated patterns engraved on it, and an ancient key still floating beside it.
mute in my heart【open】
The key was inserted into the keyhole, and the box opened after rotating, and a spherical object shining crimson appeared.
Before he could see what it was, just like last night, a prompt box popped up.
【Congratulations, you get a pure natural pollution-free apple×10……】
