Supreme Pharmacist System

The skin flakes were under the electron microscope, and nothing unusual was found.

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

But he had to wait until tomorrow to test the mutated aphid to make sure there was no virus before he could rest assured.

After finishing the work here, it happened to be lunch time.

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

Shi Lei, who had just made the electrophoresis gel and was about to kill the mice, said without raising his head, "What's the matter, are you done?"

Zhou Wen said with a smile: "I'm so busy, I can just change the data later, you know."

It usually takes 2 to 3 days for an electrophoresis process to run, and PCR is required. After two or three days of hard work, it is often found that the experimental data is seriously unreasonable.

Then there's f*ck, Jesus, damnit, all yelling.

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

This is basically the unspoken rule of biological students, and most biological students have done this before.

Shi Lei chuckled twice, he was also a person who came here, nodded and said: "In this case, then you go back to rest first, I can take care of it myself. By the way, bring us a meal by the way."

Zhou Wen turned around, leaned against the test bench and said, "Why go back, I don't have a girlfriend."

Lin Jiayi, who was wearing a white coat and looked at the microscope with her back to them, turned around and asked, "Hey Zhou Wen, do you still have contact with Qu Fangfang?"

Qu Fangfang turned out to be the most beautiful girl among the few girls in the laboratory. She has a gentle personality and a small family. She is an ideal wife for boys.

It's a pity that I went to practice after the year.

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

"It's nothing." Lin Jiayi said something casually, and then said with a smile: "Hey Zhou Wen, you invite me to dinner, how about I be your girlfriend?"

Zhou Wen curled his lips and said, "As long as you women keep their word, my child will be soy sauce now."

Shi Lei laughed out loud.

Lin Jiayi also turned around with a smile.

Just kidding, she has finished her second year of graduate school, and she knows exactly what kind of boyfriend she should find.

Zhou Wen turned his head and said with a smile: "Brother Lei, do you want to help? If not, I will go back to watch the drama."

As soon as Shi Lei heard that he was going back to watch the drama, he raised his head and said with a silly smile: "Then you should stay, as Lan Lan just invited me to watch a movie in the afternoon."

Zhou Wen urged: "Then why don't you hurry back and tidy up, and try to successfully intubate at night."

Shi Lei smiled naively.

Similar to Zhou Wen, Shi Lei's family conditions are not very good, plus he looks like a blind monk, he can't speak sweetly, he is about to graduate from graduate school, and he hasn't even kissed a girl until now.

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

Accepted the offer.

"Then I'm really leaving?"

"Go."

Shi Lei handed the mouse to Zhou Wen, turned around and left the laboratory.

"Remember to bring us food."

"Know……"

Here, Zhou Wen pinched the mouse's neck with one hand and pressed it on the operating table, while the other hand grabbed the mouse's tail, lifted it up, and with a "click", gave the mouse a "cervical spine decapitation" Law".

No pain at all.

Then quickly disembowel the mouse, cut off the mouse's thigh bone with scissors, and peel off the muscles and fascia outside the leg bone.

After rinsing, cut the femur, extract the bone marrow, then wash the femur bone marrow with low-osmotic fluid, and finally put the rinsed "rinsing fluid" into test tubes in equal parts for each plant.

Then another mouse was strangled, and after the bone marrow was pumped, the flushing solution was prepared step by step according to the above steps, and the previous flushing solution was prepared.

After adjusting the weight according to the AB group, go to the centrifuge and start centrifuging.

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

However, it usually takes 2 to 3 days for a gene extraction process. Those large-scale laboratories and research institutes that pay attention to efficiency will hand over the gene extraction work to the laboratories of various universities.

A mouse can theoretically extract 4 to 8 strains of gene fragments, but normally only 4 strains are extracted.

Of course, these are charges.

The current market price of a plant is about 400-500.

...

Just after centrifuging here, Shi Lei came back with a packed meal.

After eating in the office outside, Zhou Wen was going to do electrophoresis analysis, commonly known as "running electrophoresis".

This has been initially contacted in high school.

It is to use agarose gel to make a gel plate, so that the sample is electrophoresed on the gel plate, so it is also called "running gel", which can be used to detect DNA chains.

In addition to running electrophoresis, another method is electron microscope observation, which saves a lot of time compared to running electrophoresis.

However, for electron microscope observation, glass slides need to be prepared and genes need to be stained. During this process, time, techniques, temperature, and possible contamination may lead to extraction failure, thereby wasting all previous efforts.

Therefore, novices generally run electrophoresis honestly.

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

Want to see how the Eye of True Sight introduces DNA?

He raised the test tube in his right hand and gently shook it twice against the light in front of the console. At the same time, he narrowed his eyes slightly, staring closely at the liquid in the centrifuge tube.

What Zhou Wen couldn't believe was that the image of the DNA chain of the white mouse actually appeared in front of his eyes, including the broken covalent bonds.

"My mother..."

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, spread his hands, narrowed his eyes slightly, and imagined the "Eye of True Seeing" in his mind.

With a "swish", his hand was as clear as a glass slide under a microscope.

But in the next second, he couldn't be happier. He saw staphylococcus, staphylococcus aureus and long strips of E. coli all over the palm of his hand...

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

In addition, the inside of the nail crevice is like a nest of bacteria, which is crowded with all kinds of bacteria, which looks very disgusting.

I have washed my hands. I really don’t know how many bacteria there will be if I don’t wash my hands?

"Fuck~" Zhou Wen shook his hands twice in fright, and then remembered that bacteria cannot be shaken off, so he hurried to wash his hands again.

He knows that there are a lot of bacteria on human hands, but they are all made of bacterial slides and observed under a microscope.

Because the human hand is opaque, there is no way to see it directly.

Because of this, he has never had such an intuitive visual shock, and for the first time realized the importance of washing hands.

Zhou Wen rolled up his sleeves, first washed his hands with alcohol-based hand sanitizer, then found nail clippers, carefully trimmed the dirty nails, and then washed his hands carefully again.

At this time, with the eyes of true vision, more than 90% of the bacteria on the hands have been eliminated, and only a small number of stubborn bacteria are still attached to the finger crevices and skin folds.

Zhou Wen said speechlessly: "It's no wonder that experiments often fail. It's no wonder that the success rate is high based on the number of bacteria in my hand."

Back in the laboratory, I looked at the rubber gloves on the table with the eyes of true sight, and found that they were also covered with bacteria.

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

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

Not surprisingly, a clear DNA image appeared in front of my eyes.

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

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

But now that he can directly see the DNA, it can be said that the most cumbersome and failure-prone procedure is omitted.

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

Zhou Wen secretly said: "Could it be that the extraction failed?"

After putting it down, he picked up another tube of serum from group B, squinted his eyes and looked at it, but he still didn't see the DNA strand.

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

This also shows that the extraction of group B really failed.

"Obviously all the processes are exactly the same, I don't know which link is wrong?" Zhou Wen frowned and thought.

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