Leaving the specimen processing team on the third floor, Zhou Wen hurriedly went to the virus testing team on the fourth floor.

It's a quarter past ten o'clock, and if you hurry up, you can make it before eating, so that you can leave work on time in the evening.

On the way, he turned on the system, and the task requirements popped up in front of him.

[Mission: Help Sun Jing's friend do virus testing.]

Rewards: 300 subject experience, 300 points, 1 chance to open the box (Black Iron)

Do you accept it?】

Seeing that the reward was a black box again, Zhou Wen was a little amused.

Based on the experience of these two unpacks, he found that the value of unpacking items depends largely on the difficulty of the task.

The more difficult the task, the higher the value of the items opened, while the easier the task is, the lower the value of the uncrated items.

And from the subject experience and points awarded, you can probably guess this.

Zhou Wen chose to accept.

After arriving at the virus detection team, Zhou Wen found Luo Siyu, the deputy of Yang Liqun, and explained his intention straight to the point.

Luo Siyu naturally knew Zhou Wen too, but he wasn't very familiar with him, and when he heard his words, he happily agreed.

Anyway, Zhou Wen did it himself, and he didn't need her to help give the green light, which was tantamount to selling favors and helping the virus testing team reduce the burden, so why not?

Luo Siyu accompanied him to the virus testing laboratory, found Sun Jing's friend's virus sample tissue in the ultra-low temperature storage library, and greeted the team members, allowing Zhou Wen to use the experimental equipment in the laboratory before leaving.

Here, as soon as Zhou Wen waited for Luo Siyu to leave, he immediately started the electrophoresis experiment.

The sample tissue has been frozen, otherwise it would have to wait 24 hours.

The steps are similar to those in university laboratories, liquid nitrogen is added to the mortar, the sample cells are crushed, sterile water is added and the grinding continues, DNase and RNase are added before extraction, the host gene fragments are removed, and then the centrifuge is placed to start centrifugation.

During the whole process, Zhou Wen's movements were quite rough, and the seven or eight inspectors in the laboratory were dumbfounded.

Is this Nima doing virus testing, or is he doing a live show?

"What is he doing, is it funny?"

"I don't know, why don't you ask him. ”

"Hey, buddy, what are you doing?" asked a male inspector with glasses, who couldn't help it.

Zhou Wen, who was standing next to the small centrifuge and waiting, turned his head and said with a smile: "Virus detection." ”

The man with glasses said funny: "You can't extract virus DNA at all." ”

Zhou Wen smiled, "It's okay." ”

He observed the whole process with his true eye, which seemed to be rough, but in fact it was coarse and fine, plus the virus DNA did not need to be amplified, and the extraction concentration was not important, so naturally it was how fast and how to come.

But the man with glasses didn't know, seeing Zhou Wen's insistence, he shook his head and walked away funny.

The other inspectors in the laboratory all laughed secretly when they saw the man with glasses retreating.

Here, Zhou Wen and others quickly extracted the supernatant after centrifugation, centrifuged again after blowing, and finally dropped it into the gel electrophoresis machine to start virus comparison and analysis, that is, compared with the NCBI gene virus database in the United States to find out what virus it is?

The process is still rough, and there is a taste of "rushing", as if I am afraid that I will be slow and will not be able to eat lunch in time.

There were two female inspectors who couldn't help but laugh out loud.

This guy is so funny.

In the entire testing center, there are hundreds of experimenters, researchers, and inspectors, who is not careful and careless in testing, for fear that which link will make a mistake and lead to the abandonment of previous efforts?

This Lord alone is a miracle with great strength.

If the virus can be detected, it will not come out of the west.

After Zhou Wen completed the electrophoresis testing procedure, he looked at the time, and it was exactly 11:30 to catch up for dinner.

He stretched his arm, and when he turned his head, he saw that everyone in the lab was staring at him.

Zhou Wen touched his face and asked, "What's wrong?"

Everyone was amused by Zhou Wen's innocent expression, and took off their gloves with a smile.

......

After lunch, Zhou Wen didn't have anything to do, and the virus test results would not come out until five o'clock in the afternoon.

Anyway, it was okay for the time being, so he went to the inpatient department to take a look.

The old lady was discussing with the attending doctor in the office about Guo Baichun's discharge from the hospital in the afternoon.

The attending doctor understands Guo Bochun's condition, his cancer cells have completely spread, and he is just dragging his feet in the hospital, and now that the old lady has asked to be discharged, he has nothing to say.

After explaining the medication and dosage to the old lady one by one, the attending doctor signed the discharge form - agreeing to be discharged.

The old lady had already packed up the things, and Zhou Wen and the nurse carried Guo Baichun into a wheelchair, and then pushed him downstairs with the old lady.

The hospital's full-time escort car was parked under the canopy at the entrance, and in addition to the driver, there was also a doctor on board.

Sending Guo Baichun to the car, the old lady patted Zhou Wen's hand and said, "Okay kid, you can go back to work." ”

"Hello~" Zhou Wen nodded, quietly stuffed the painkiller to the old lady, and then said goodbye to Guo Baichun, "Uncle Guo, goodbye." ”

Guo Baichun was in good spirits at the moment, except for being thinner, nodding and showing a smile that was not too good-looking, and nodded at him, "Goodbye." ”

After seeing the old lady leave, Zhou Wen returned to the PCR laboratory of the testing center.

Help Bian Wenhao and Su Qi to prepare reagents.

Time passed quickly, and in a blink of an eye, it was half past four in the afternoon, and Zhou Wen left the PCR laboratory and went to the virus testing team.

After another forty minutes of waiting, the test results came back.

Zhou Wengang picked up the electrophoresis report map, and several heads were surrounded by "hula" next to him, staring at the test report in his hand.

I saw the electropherogram report in Zhou Wen's hand, the electrophoresis band on the right side was clearly visible, and the analysis report on the left side, one of the polyoma virus (Py) test results were positive, and the test results at the bottom showed that SV40, BKV, and JKV were not excluded, and it was recommended to ......

WTF？？？

Can this be detected?

The several experimenters surrounding Zhou Wen all had hellish expressions.

Some people began to wonder in their hearts, was this test report casually printed out by Zhou Wen from the computer?

There are also people who wonder if their previous operation method is wrong?

To extract viral DNA, the action should be rough and vigorous, and the miracle should be vigorously produced?

But soon they all denied their cranky thoughts in their hearts.

It is impossible to fight indiscriminately in the report, every report they issue represents a human life and a family, who dares to mess around?

Get into a jam!

As for the miracle of the force, I can only think about it.

In the past, they were the same as Zhou Wen, their actions were also very rough, but in exchange for failures again and again, the facts told them that vigorous efforts could not produce miracles, only failures.

As for Zhou Wen, this guy is a pervert......

"That, how did you test it?" said the man with glasses who said that Zhou Wen couldn't extract the DNA of the virus, asked a little embarrassed at this time.

Zhou Wen laughed and said, "It's the same as you." ”

The man with glasses was depressed, of course he knew the same, they had been staring at Zhou Wen for a day today, and they wanted to wait for the electrophoresis results to come out and see what the expression on his face would be?

Instead, they were shown off.

The man with glasses was just about to ask something more, but when he saw the smiling expression on Zhou Wen's face, his heart suddenly moved.

He knew that Zhou Wen must be pretending to be a pig and eating a tiger, and he was actually a master of virus detection.

People know their minds from beginning to end, but they don't break it.

They were still waiting to see the joke, but they didn't expect it to become a joke.

The glasses man's face is hot.

But it soon dawned on him that this was a good opportunity to learn from experience.

He smiled and asked, "My name is Qin Haitao, what's your name?"

"Zhou Wen. ”

"Then I'll call you Teacher Zhou. Qin Haitao said very sincerely.

Zhou Wen has never enjoyed the true respect of his peers, just like Sun Jing calling him an expert, in fact, it is somewhat ridiculous.

And Qin Haitao is different, he can hear that this young man who looks two or three years older than him, his tone is very sincere.

Zhou Wen said modestly: "Don't don't, I'm just like you, I'm an ordinary experimenter." ”

Qin Haitao also ignored it and said, "Hello Mr. Zhou, then, I would like to ask, how did you do it? Why is it easy for me to fail the detection if I do it with a little improper operation like you?"

Zhou Wen was modest in his mouth, but he was very happy in his heart, and said with a smile: "That's because you didn't grasp some key points, such as ......"

For the sake of Qin Haitao's respect for him, Zhou Wen made an exception and told him about several key precautions in the process of virus extraction.

These key points are all experiences that he has seen with his true eye, and no amount of money can buy them.

Of course, it is impossible for him to say such a technological innovation point as the concentration of permeate, this is the guy he eats.

Qin Haitao and another man listened attentively beside him, with a look of sudden realization on his face from time to time.

As for the others, they probably felt embarrassed and walked away after listening to two sentences.

After Zhou Wen spoke for 5 minutes, he paused and said, "Okay, as long as you master these key points well, you won't fail so easily in the future." ”

Qin Haitao nodded, he felt that for a while, many things that he couldn't figure out before, but now they suddenly opened up, and there was a feeling of seeing the blue sky through the clouds.

Qin Haitao said gratefully: "Thank you, Mr. Zhou, for your guidance. ”

"Thank you, Mr. Zhou. ”

"You're welcome~"

After speaking, Zhou Wen raised the electrophoresis report in his hand and said, "What is the next process? ”

Qin Haitao smiled: "This is simple, you give it to me, and I will help you enter it into the system......
