DNA extraction, Zhou Wen is now familiar with the road, and there is no difficulty at all.

It's just that during the rinse, he added a micro-dilution to the low permeate to reduce the concentration of the low permeate so that a high concentration of DNA strands could be obtained.

This is the result of his experiments during this time.

Of course, the concentration of the permeate is one thing, and the rest of the methods, temperature, and contamination control will affect the concentration of the DNA strand.

By half past eleven, Zhou Wen had already fixed his DNA and was ready to draw it on the slide for electron microscopy 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 of the scientific research institute downstairs.

A few colleagues who had been secretly observing him next to him were all eye-opening.

Each of them will do electron microscopy observation, but every step is cautious, for fear of pollution and errors, where is Zhou Wen so chic, it seems to ...... He could see the DNA as well.

There are only two outcomes to this situation.

Or stupid.

Either.

As for which one it is, we will know it after doing electron microscope observation.

It happened that Wu Yan came over at this time and called everyone for lunch.

"How's it going?"

"Well, do an electrophoresis observation in the afternoon. ”

Wu Yan glanced at the centrifuge and said in surprise: "The DNA has been fixed?"

Zhou Wen nodded: "Hmm." ”

Wu Yan: "......"

It's only been an hour and a half, what kind of devilish speed is this?

Wu Yan: "Let's go, let's go eat." ”

Everything will be counted in the afternoon when the results come out.

Out of the building, Wu Yan handed a white magnetic card to Zhou Wen, "Well, this is a temporary card, you use it first, and then I will send you an official one after completing the entry procedures." ”

"Thank you~" Zhou Wen took it and looked at it, there are affiliated hospitals and temporary cards in the north, and there are numbers below.

Wu Yan followed and said: "As for accommodation, can you solve it yourself for the time being? ”

Zhou Wen knew that the dormitory would definitely wait until the employment contract was signed before talking, so he nodded and said, "Well, okay." ”

The two chatted a few more words, and Wei Zhaogong, who was following beside him, took the initiative to ask, "Where is your hometown?"

Zhou Wen: "Jiangdu's." ”

Wei Zhaogong was pleasantly surprised: "Ah, you are from Jiangdu, why is my accent so kind, hehe~ I am from Taixing, very close to you." ”

"Well, yes, only fifty or sixty kilometers. ”

"How old are you?"

"22, what about you?"

"I'm 24. You're only 22, you don't look like ......."

All the way to the hospital staff canteen east of the inpatient department.

Not to mention, the food in the first courtyard is still very good, and all kinds of dishes are also complete.

"The food in your hospital is good. ”

Wu Yan smiled: "Compared with the university, it is still a little worse." ”

"I look okay, is it because I have eaten too much college food, and I like the new and hate the old?"

"I often miss the university cafeteria ...... now"

After the meal was ready, Zhou Wen followed Xu Jiajia and them to the exclusive place with a plastic dinner plate and sat down.

At a glance, there were all nurses in white coats, all of whom looked very smart, laughing "clucking", like a little hen, and the flirtatious Zhou Wen, a bachelor, was itching in his heart.

However, he knows that these little nurses are all human spirits, and they don't have the ability to open BBA with one hand, so they can't play at all.

The meal took about twenty minutes.

There was more than an hour of message time after the meal, and the testing center went to work at half past one.

Anyway, there was nothing to do, Zhou Wen was walking around the hospital, and Wei Zhaogong also accompanied him.

When they arrived at the administrative building, the two of them stood still at the base of the wall, and Wei Zhaogong took out a bag of Xiaosu cigarettes from his pocket and gestured like Zhou Wen.

Zhou Wen took out one of his hands, took out the lighter from his pocket, and lit it for Wei Zhaogong first, and then for himself.

Wei Zhaogong smiled: "How many years have you smoked?"

Zhou Wen: "Five years. I started smoking it in my junior year of high school. ”

"Then I'm earlier than you, I smoked it when I first started in high school. ”

Wei Zhaogong said and took a sip, and then said: "At that time, I just went to high school, in order to integrate into the dormitory collective as soon as possible, others scattered it to me, so I continued to smoke, who knew that I would be addicted to smoking." ”

"Hehe, I'm pretty much the same~"

Wei Zhaogong chatted a few more words about high school life, and then said to the west building: "Behind is the dormitory for the regular staff of the hospital, Jiang Hexuan and I live in the building to the north, and you should live there when you turn around." ”

"Are you and Jiang Hexuan together?"

"Well, we're college classmates. ”

"Oh~"

Wei Zhaogong asked, "I think the Wu group is very concerned about you, do you know each other in college?"

"I don't know. Zhou Wen shook his head with a smile, and then asked, "Isn't the team leader Zhang Shuguang, why do you all call her team leader?"

Wei Zhaogong said with a smile: "The Zhang group usually has to engage in scientific research, participate in academic seminars, and be busy with the affairs of the hospital, so I don't have time to manage the PCR team at all, Wu Yan is managing it, so I ......."

"Oh, I understand~" Zhou Wen nodded with a smile.

After all, we just met, and it's impossible to talk about anything in depth.

I chatted for a while, and after a brief understanding of the situation in the hospital, I went back to the testing center.

Most of the people in the laboratory building did not come back, and only a small number of people were doing experiments.

When Zhou Wen arrived at the laboratory, he immediately began to get busy.

Electron microscope observation, perfect~

He then began to perform electrophoretic analysis.

If you want to see the concentration of DNA, you must do electrophoresis analysis, and you can't see the DNA concentration with electron microscopy.

Just when Zhou Wen was dispensing glue, Wei Zhaogong, Jiang Hexuan, Dong Wenying and Xu Jiajia went to the electron microscope one by one to look at it, and when they left, everyone had a stunned look on their faces.

They couldn't figure it out, how could they successfully extract Zhou Wen's range of action?

"It's awesome~"

At a quarter past two, Wu Yan and Zhang Shuguang came over together.

Seeing the slides on the electron microscope stage, Zhang Shuguang's eyes lit up.

"Already?"

Zhou Wen nodded, "Hmm." ”

Wu Yan smiled beside her: "It's fixed at half past eleven." ”

"Oh, is it?" Zhang Shuguang was surprised again, and said to himself in his heart: "What a fast speed." ”

He walked over to the electron microscope and looked at it, and the DNA strands were clearly visible.

Zhang Shuguang had a smile on his face, he really didn't see the wrong person.

Here, Zhou Wen has just configured the electrophoresis gel, then piped, centrifuged, and dropped into the gel electrophoresis machine tank to start electrophoresis.

The next thing is to wait.

Zhang Shuguang waited for him to finish his work, and said with a smile: "Take a sample of the plant and follow me." ”

Zhou Wen took a piece of mouse DNA from the centrifuge and put it in the ice box, and then followed Zhang Shuguang out of the laboratory.

As soon as the two of them walked on their front feet, Xu Jiajia pulled Wu Yan behind them and asked, "Hey Wu Group, what's the situation with this Zhou Wen?"

"Whatever, it's a normal practical interview. ”

"That's not right. When I came here last year, Zhang Group never showed up from beginning to end. ”

"Hehe~"

Wu Yan smiled, seeing that Xu Jiajia and the others were looking at her blankly, and after thinking about it, everyone would know anyway, so she smiled and said: "He is a little different from you, you are a contract system, and he is an employment system, so Zhang Group needs to personally check it." ”

Xu Jiajia exclaimed: "What, he has a compilation?"

The other three people in the laboratory also had confused expressions.

No wonder I attach so much importance to it, it turned out to be a formal employee interview.

Although a few people didn't say anything, they were all envious, jealous and hateful in their hearts.

The same people, they are regular employees when they first arrive, and they work hard every day to do experiments, but they turn out to be contract workers, and the gap between people has opened up all of a sudden.

When they really get mixed up one day, maybe they will already be the leaders of the hospital.

Wu Yan saw everyone's strange expressions, guessed what they were thinking, and said with a smile: "Zhou Wen was introduced as a talent, so he was treated specially, don't have any ideas." ”

Hearing Wu Yan's words, Xu Jiajia and the others suddenly thought of Zhou Wen's performance in extracting DNA, and their hearts suddenly dawned.

This kind of talent, given a establishment, is barely strong, so-so, and almost feasible.

But when I thought that Zhou Wen had an establishment when he first came, and they had been working for a year, and the salary of the establishment was still far away, my heart couldn't help but start to sour again......
