Dandruff was under the electron microscope and no abnormalities were found.

Two-thirds of the big stone in Zhou Wen's heart was put down.

However, he will have to wait until the mutant aphid is detected tomorrow and he will be completely relieved after confirming that there is no virus.

After the work is over here, it is lunch time.

Zhou Wen came to Shi Lei and asked with a smile: "Brother Lei, do you need help?"

Shi Lei, who had just finished electrophoretic glue and was about to kill the teenage mouse, said without raising his head: "What's wrong? Are you finished?"

Zhou Wenxiao said, "What's the point of me? Just change the data casually, you know."

It usually takes 2 to 3 days to complete an electrophoresis process, and PCR is required. After working hard for two or three days, you often find that the experimental data is seriously unreasonable.

Then there is f*ck, Jesus, damnit, and a roar.

Next, if you don't plan to do it again, you can only forge the data.

This is basically a hidden rule of biological life, and most biological life has done this.

Shi Lei laughed twice, and he was also a person who came here, nodded and said, "Since that's the case, then you can go back and rest first, I'll do it myself. By the way, I'll bring us some food."

Zhou Wen turned around, leaned against the test bench and said, "What are you doing when you go back? You don't have a girlfriend."

Lin Jiayi, wearing a white coat and looking at the microscope with her back facing her back to her, turned around and said, "Hey Zhou Wen, do you have any contact with Qu Fangfang?"

Qu Fangfang turned out to be the most beautiful among the girls in the laboratory. She has a gentle personality and a beautiful girl. She is the ideal wife candidate in the minds of boys.

Unfortunately, I went for an internship after the New Year.

Zhou Wen replied: "I haven't contacted you, what's wrong?"

"Nothing." Lin Jiayi said casually, then laughed: "Hey Zhou Wen, you invite me to dinner, how about I be your girlfriend?"

Zhou Wen curled his lips and said, "If you women keep your word, my child will be soy sauce now."

Shi Lei laughed loudly.

Lin Jiayi also turned around with a smile.

Just kidding, she has already become a second-year student, so she knows very well what kind of boyfriend she should find.

Zhou Wen turned around and smiled, "It's really Brother Lei, do you want to help? If I don't want me, I'll go back to watch the show."

When Shi Lei heard that he was going back to watch a show, he looked up and said silly, "Then you should stay. Lanlan happened to ask me to go to the movie in the afternoon."

Zhou Wen urged: "Then why don't you go back and clean up quickly and strive to successfully intubate the tube at night."

Shi Lei smiled silly.

Like Zhou Wen, Shi Lei's family conditions are not very good. In addition, he looks like a blind monk and does not speak sweetly. He is almost graduated from graduate school and has never even kissed a girl.

It is rare to meet a girl who doesn't dislike him, and everyone is very happy for him.

I also accepted the takeover.

"Then am I leaving?"

"Go."

Shi Lei handed the little mouse in his hand to Zhou Wen and turned around and left the laboratory.

"Remember to bring our meals for us."

"Know……"

On this side, Zhou Wen pinched the mouse's neck with one hand and pressed it on the operating table. With the other hand, he grabbed the mouse's tail with the other hand, lifted it up, and with a "click", he gave the mouse a "cervical vertebrae decapitation method".

No pain at all.

Then quickly break the belly, use scissors to cut off the mouse's thigh bone, and peel off the muscles and fascia outside the leg bone.

After rinsing, cut open the thigh bones, extract the bone marrow, then rinse the thigh bone marrow with low permeability solution, and finally put the rinsed "rinse solution" into the test tube in equal parts for each plant.

Then, a little white mouse was strangled to death, and after the bone marrow was pumped, the rinse liquid was prepared step by step according to the above steps, and the previous rinse liquid was prepared, and the weight was prepared according to the AB group, and then the centrifuge was put on the centrifuge.

The genes of mice are 95% similar to human genes, so many large laboratories use mice's genes to perform various drug tests.

However, it usually takes 2 to 3 days to complete a gene extraction process. Large laboratories and research institutes that pay attention to efficiency will hand over the gene extraction work to laboratories of major universities.

In theory, a mouse can extract 4 to 8 gene fragments, but 4 are extracted normally.

Of course, these are charged.

The current market price of one plant is about 400 to 500.

...

Just as the centrifugation was completed here, Shi Lei came back with the packed meal.

After having dinner at the office outside, Zhou Wen was preparing to do electrophoresis analysis, commonly known as "electrophoresis running".

This has been initially exposed to in high school.

It is to use agarose gel to make glue plates to allow the samples to electrophoresis on the glue plates. Therefore, it is also called "running glue" and can be used to detect DNA strands.

In addition to electrophoresis, another method is electron microscopy observation, which saves more time than electrophoresis.

However, if you observe electron microscopy, you need to prepare a slide and also to stain the gene. During this process, time, techniques, temperature, and possible pollution may lead to the failure of extraction, and all previous efforts will be wasted.

Therefore, novices usually go through electrophoresis honestly.

Zhou Wen took the extraction gun and prepared to extract the supernatant and then "pray". At this moment, he suddenly thought of the "Eye of True Vision".

Want to see how the True Vision Eye introduces DNA?

He raised the test tube in his right hand and shook it gently at the light in front of the operating table twice. At the same time, his eyes narrowed slightly and stared at the liquid inside the centrifuge tube.

What Zhou Wen couldn't believe was that the image of the DNA chain of the white mouse appeared directly in front of him, and he could see clearly, including the broken covalent bonds.

"I'm damn..."

Zhou Wen was so excited that he almost jumped up.

His eyes can actually see DNA clearly. Doesn’t this mean that his eyes have caught up with the electron microscope?

He immediately put down the centrifuge tube in his hand, took off the rubber gloves and spread his hands, narrowed his eyes slightly, and imagined the "eye of true vision" in his mind.

With a "swish", his hands were as clear as a slide under the microscope.

But the next second he couldn't be happy, and he saw Staphylococcus, Staphylococcus aureus and strips of E. coli were covered with the palms of his hands...

There are also various other bacteria and microorganisms crawling around in the palm of your hand.

In addition, the cracks in the nails are like bacterial nests, and they are filled with all kinds of bacteria, which looks very disgusting.

I've washed my hands. I really don't know how many bacteria will be if I don't wash my hands?

"Damn~" Zhou Wen was so scared that he shook his hands twice before he remembered that the bacteria could not be shaken off, so he quickly ran to wash his hands again.

He knew that there were a lot of bacteria on human hands, but they were all made of bacteria and then placed under a microscope to observe.

Because human hands are not transparent, they cannot see clearly.

Because of this, he has never been so intuitive and visually shocked, and he also realized the importance of washing hands for the first time.

Zhou Wen rolled up his sleeves, washed his hands with alcohol-containing hand sanitizer, then found a nail clipper, carefully trimmed the dirt-hiding nails, and then washed his hands carefully.

At this time, use the eyes of true vision to see that more than 90% of the bacteria on the hands were eliminated, and only a small number of stubborn bacteria were still attached to the fingers and skin folds.

Zhou Wen said speechlessly: "No wonder the experiments often fail. It is strange that the success rate is high based on the number of bacteria in your hands."

Back in the laboratory, I looked at the rubber gloves on the table with my true eyes and found that it was also covered with bacteria.

"Huh~" Zhou Wen picked up the inoculation stick on the table next to him, picked up the gloves and threw them into the scrap bucket, and then found a pair of sterile gloves to put on.

After everything was done again, Zhou Wen picked up the A-group centrifuge tube containing the mouse gene fragments and observed again.

As expected, a clear DNA image appeared in front of me.

This shows that the gene extraction of the mice was successful.

The purpose of electrophoresis and electron microscopy is to detect whether there is DNA in the test tube.

Now that he can see DNA directly, it can be said that it saves the most complicated and most prone to failure of the program.

Then he picked up the B group centrifuge tube and looked at it, but this time he did not see the DNA strand.

Zhou Wen said secretly: "Has the extraction failed?"

After putting it down, I picked up another tube of Group B's clear liquid, squinted my eyes and looked at it, but I still didn't see the DNA strand.

He picked up one of the tubes in Group A again, but this time he could see clearly.

This also shows that Group B really failed to extract.

"Even though all the processes are exactly the same, I wonder which link went wrong?" Zhou Wen frowned and pondered.

He decided to do an electrophoresis analysis first to see if what the True Vision Eye saw was real, and then study the errors in the operation...
