Chapter 19 - Devil speed
DNA extraction, Zhou Wen is now familiar with the road, without any difficulty at all.
It’s just that when washing, he added a micro-diluent to the low osmotic solution to reduce the concentration of the low osmotic solution, so that high-concentration DNA strands can be obtained.
This is the result of his experiment during this period.
Of course, the concentration of the low osmotic fluid is one aspect. The other methods, temperature and pollution control, etc., will affect the concentration of DNA strands.
At 11:30, Zhou Wen had already fixed the DNA, and was about to draw it to the glass slide for electron microscope observation.
The whole process took an hour and a half, and the whole process was like clouds and water, clean and neat, faster than the old experimenters in the scientific research institute downstairs.
has been secretly observing his colleagues next to him, all of which are eye-opening.
Each of them can do electron microscopic observations, but every step is careful, for fear of pollution and mistakes, where is as cool as Zhou Wen, as if… he can see DNA.
There are only two results in this situation.
or stupid.
either awesome.
As for which one it is, you will know after the electron microscope observation.
It happened that Wu Yan came over to call everyone for lunch.
“How are you doing?”
“Well, do an electrophoresis observation in the afternoon.”
Wu Yan glanced at the centrifuge and said in surprise: “The DNA is already fixed?”
Zhou Wen said little by little: “Yes.”
Wu Yan: “……”
This is only one and a half hours, what kind of devil speed is this?
Wu Yan: “Let’s go, go eat.”
Everything can only be counted when the results come out in the afternoon.
Out of the building, Wu Yan handed out a white magnetic card to Zhou Wen, “Here, this is a temporary card. You use it first, and will send you the formal one after finishing the entry procedures later.”
“Thank you~” Zhou Wen took it over and looked at it. To the north, there is an affiliated hospital and a temporary card, and there is a number below.
Wu Yan followed: “As for accommodation, can you solve it by yourself for the time being? You can arrange a dormitory for you after the contract is finalized, or rent a subsidy.”
Zhou Wen knew that the dormitory must wait for the signing of the employment contract before negotiating, nodded and said, “Yes, yes.”
The two chatted a few more words, and Wei Zhaogong, who was next to him, actively asked, “Where is your hometown?”
Zhou Wen: “Jiangdu’s.”
Wei Zhaogong said in surprise: “Ah, you are from Jiangdu, why do I have such a friendly accent, haha~ I am from Taixing, very close to your place.”
“Well, yes, only fifty or sixty kilometers.”
“How old are you this year?”
“22, how about you?”
“I’m 24. You’re only 22, you don’t look like it…”
talked all the way to the hospital staff canteen east of the inpatient department.
Not to mention, the food in the first courtyard is quite good, and all kinds of dishes are also very complete.
“The food in your hospital is good.”
Wu Yan smiled and said: “Compared with university, it is still a bit worse.”
“I think it’s okay. Is it because the college food is too much and I like the new and tired of the old?”
“I often miss the university cafeteria now…”
After finishing the meal, Zhou Wen carried the plastic plate and followed Xu Jiajia and the others to the exclusive position to sit down.
I glanced around, all of them were nurses in white coats, all of them were really watery, giggling, like a little hen, the bachelor Zhou Wen was itchy.
But he knows that these little nurses are all human beings, and they don’t have the ability to open BBA with one hand.
A meal took about twenty minutes.
There was more than an hour of news time after the meal, and the testing center went to work at 1:30.
Nothing happened anyway, Zhou Wen was walking around in the hospital, and Wei Zhaogong was also walking with him.
When they arrived at the administrative building, the two stood still by the root of the wall. Wei Zhaogong took out a packet of Xiaosu cigarettes from his pocket and gestured like Zhou Wen.
Zhou Wen smoothly pulled out one, took out the lighter from his pocket, first helped Wei Zhaogong to power it, and then gave it to himself.
Wei Zhaogong smiled and said, “How many years have you been smoking?”
Zhou Wen: “Five years. I started to smoke in the third year of high school.”
“Then I am earlier than you, I started smoking in my first year of high school.”
Wei Zhaogong took a sip as he said, and then said: “At that time, I was just in high school. In order to integrate into the dormitory group as soon as possible, others scattered to me, so I continued to smoke. I didn’t know that smoking was addictive.”
“Hehe, I’m almost the same~”
Wei Zhaogong talked a few more about high school life, and then said to the west building, “Behind is the dormitory of the official staff of the hospital. Jiang Hexuan and I live in the north building. When you turn back, you should also live there.”
“Are you and Jiang Hexuan together?”
“Well, we are college classmates.”
“Oh~”
Wei Zhaogong asked: “I think Group Wu is very concerned about you, do you know each other in college?”
“I don’t know.” Zhou Wen smiled and shook his head, and then asked: “Isn’t the team leader Zhang Shuguang, why do you all call her team leader?”
Wei Zhaogong smiled and said: “Zhang Group usually does scientific research, participates in academic seminars, and is busy with the affairs of the hospital. There is no time to manage the PCR group. Wu Yan is in charge of it, so…”
“Oh, I understand~” Zhou Wen smiled and nodded.
I just met after all, and it is impossible to talk about shallow words.
I just chatted for a while, and after a brief understanding of the hospital situation, I went back to the testing center.
Most of the people in the laboratory building have not returned, only a small number of people are doing experiments.
Zhou Wen arrived at the laboratory and immediately became busy.
electron microscope observation, perfect~
Then he started to do electrophoresis analysis.
If you want to see the concentration of DNA, you must do electrophoresis analysis. The DNA concentration cannot be seen under electron microscope.
Just when Zhou Wen was distributing glue, Wei Zhaogong, Jiang Hexuan, Dong Wenying, and Xu Jiajia looked at the electron microscope one by one. When they left, everyone had a look of surprise on their faces.
They couldn’t figure it out, how can they extract Zhou Wen’s motion range successfully?
“It’s awesome~”
At a quarter past two, Wu Yan and Zhang Shuguang came over.
Seeing the slides on the electron microscope stage, Zhang Shuguang’s eyes lit up.
“Already done?”
Zhou Wen nodded, “Yes.”
Wu Yan smiled next to him: “It will be fixed at 11:30.”
“Oh, is it?” Zhang Shuguang was surprised again, and said to himself: “It’s so fast.”
He walked to the electron microscope and observed it. The DNA strands were clearly visible.
A smile appeared on Zhang Shuguang’s face, and he didn’t see the wrong person as expected.
Here, Zhou Wen has just prepared the electrophoresis gel, then pipetted, centrifuged, and dropped it into the tank of the gel electrophoresis machine to start electrophoresis.
The next step is to wait.
After Zhang Shuguang waited for him to finish, he smiled and said, “Take a sample and follow me.”
Zhou Wen took a white mouse DNA from the centrifuge and put it into the ice box, and then followed Zhang Shuguang out of the laboratory.
As soon as the two people left with their front feet, Xu Jiajia pulled Wu Yan and asked, “Hey Wu Group, what’s the situation in this Zhou Wen of UU reading www.uukanshu.com?”
“What kind of situation is it a normal practical interview.”
“That’s not right. For a normal hands-on interview, you need a big guy like Zhang Zu to interrogate him? When I came last year, Zhang Zu never showed up from beginning to end.”
“Hehe~”
Wu Yan smiled. Seeing Xu Jiajia and the others looking at her eagerly, after thinking about it, everyone will know when they look back anyway, so she smiled and said, “He is a little different from you. You are under a contract system, and he is under an employment system. , That’s why Zhang Group needs to personally check it.”
Xu Jiajia exclaimed: “What, does he have a system?”
The other three people in the laboratory also have a dumb expression.
No wonder it pays so much attention to it, it turned out to be a formal employee interview.
Although a few people didn’t say anything, they were full of envy and hatred in their hearts.
are also human beings. They are full-time employees when they first arrived, and they work hard and experiment every day, but they are contract workers. The gap in being a human being suddenly widened.
When they are really mixed enough to have an establishment, maybe they are already leaders of the hospital.
Wu Yan saw that everyone had strange expressions, guessed what they were thinking, and smiled: “Zhou Wen was introduced as a talent, so he treats it specially. Don’t have any ideas.”
Hearing Wu Yan’s words, Xu Jiajia and others suddenly thought of Zhou Wen’s performance in extracting DNA, and suddenly realized.
This kind of talent, given a staff, reluctantly, so-so, almost capable.
But when I thought that Zhou Wen had a weaving just after he came here, and they have been working for a year, the weaving benefits are still far away, and I can’t help but feel sour again…
