"Did you do this?" Yuan Weihong pointed to the label FZY 1016 on the six-hole petri dish and asked.

"Well, Master, yes, no problem, right?" Fang Ziye is sorting out the mask at this time.

The teacher summoned him, and Fang Ziye could only rush to the laboratory quickly, not daring to delay at all. At this time, whether the slippers were pierced or not, Fang Ziye didn't have time to identify.

Well, when you enter the cell room, in principle, you can't wear your own shoes, you need to buy a separate pair of shoes and place them on the shoe rack outside the cell room for later use.

Yuan Weihong continued to examine it a few more times, and continued to focus on the field of vision under the mirror: "The first time you did it, you did it like this?" ”

"Genius?"

"Who did it for you?" Yuan Weihong's thinking is preemptive.

"Master, I really did it myself, how can the senior brothers in the laboratory have time to help me do it? However, Senior Sister Luo Tingzhu gave some advice. But it didn't help. Fang Ziye had already guessed that his operation should not be bad, so he was relieved.

Just looking at my feet, it seems that these slippers are really not my own.

Looking at the door, Fang Ziye found that there was a head, and the cat looked inside at the door frame of the cell room, as if it was Luo Tingzhu.

Fang Ziye was helpless, so he could only stretch his feet.

He was in a hurry just now, thinking that there was a problem with the cells in his scratch experiment, and he was discovered by the teacher, so he found a pair of familiar slippers, and he didn't even look at the small name label.

The slippers in the laboratory are basically the same, and if you don't look at the name label, you won't have time to recognize them.

The cat's head flinched in an instant.

Yuan Weihong also noticed Fang Ziye's small movements, and thought about it carefully: "Whose shoes are you wearing?" ”

"Your shoes are on my feet." Yuan Weihong had also been in the laboratory before, so he naturally knew the corresponding rules.

Fang Ziye shook from side to side a few times: "Master, it's okay." ”

"Scratch experiments are generally taken at 0, 6, 12, and 24 hours. Why don't you come by the standard? Yuan Weihong turned his head and asked.

This is also the purpose of his call to Fang Ziye, October 16 was yesterday, Fang Ziye obviously did not observe and take pictures properly.

"Master, giant cell tumors of bone grow relatively slowly, isn't it possible to delay taking pictures?" Fang Ziye asked.

"You say it's slow, it's slow? Are the pictures published in the article all the original material? ”

"If you don't come, just wait for someone else to finish it for you? Even if it's blank, invalid, meaningless data, it's not experimental data? Yuan Weihong seemed to have found the opportunity to knock and asked.

Fang Ziye immediately felt a little embarrassed.

Fang Ziye really didn't pay special attention to this, mainly because he read other literature related to giant cell tumor of bone, which recorded 24h, 48h, and 72h observations at 24h or 12h intervals, rather than data records of six hours or absolute 12h.

If you don't have cognitive experience, even if you add points and improve your operation proficiency, you will still suffer.

"Master, I was wrong, I'll do it again." Fang Ziye is also honest, and he admits his mistakes.

"Wait for you to do it again, don't you need money?"

"The money allocated by the state to the project is just to make you fail if you want to?"

Yuan Weihong continued to beat: "If you say it at a small level, you are not rigorous in doing things, and if you say it at a big level, you are squandering the country's financial allocation resources at will!" ”

Yuan Weihong carefully put away the three six-well plates, and then handed them to Fang Ziye, asking Fang Ziye to disinfect the surface first and then put them into the cell culture incubator.

Fang Ziye can be honest.

However, after Fang Ziye finished putting the six-hole petri dish, he said: "I have the opportunity to invite Luo Tingzhu to have a meal, a little girl from the family, for the sake of the small cells in our group, has been guarding for so long." ”

"Thank you."

Fang Ziye's head was tilted subconsciously, which was a habitual micro-action that Fang Ziye suddenly thought.

"Transwell cell invasion experiment, will it be operated?" Yuan Weihong, as he walked towards the door, continued to ask.

Fang Ziye nodded.

"Really?" Yuan Weihong took off the cell room slippers of the sub-industry, and his movements were slightly paused. Obviously, Fang Ziye's answer will not fix him.

He will come to the laboratory today, not specifically to supervise Fang Ziye's experimental operation, it is Luo Tingzhu, a little girl, who asked him for advice, mainly because Luo Tingzhu inquired around, and no one had time to teach her, so he asked Yuan Weihong.

Yuan Weihong also had a deep memory of the little girl Luo Tingzhu, so he thought that he would come over to take a look, and by the way, he took a look at Fang Ziye's experimental progress and found that Fang Ziye's operation was exceptionally good, but there were flaws.

"It should be about the same." Fang Ziye nodded, his tone was calm, and he didn't dare to make a mistake.

"What are the experimental procedures?" Yuan Weihong didn't want Fang Ziye to be brutal.

Criticism is criticism, carelessness is carelessness.

Mommy has just entered the laboratory for less than half a month, and he has directly matured to the cell scratch experiment, such a talent, looking at the whole country, not to say that there is none, but it is certainly not very much.

After all, ordinary people have to do it for a while to understand experimental equipment, copy experimental records, culture cells and other operations.

In Yuan Weihong's eyes, Fang Ziye has always been a conscientious and reliable student, not a talented player.

There has been a slight progress step by step before, it is a matter of accumulation, and it is a matter of course, but it is not Fang Ziye who has completed a big stride. Now, not long after entering the laboratory, he has advanced by leaps and bounds, and he really can't fix Yuan Weihong.

We are two masters and apprentices, who doesn't know who?

Little Teletubbies.

"The general process is cell culture and treatment—coating the basement membrane—hydrating the basement membrane—preparing the cell suspension—seeding the cells into the upper chamber—cell fixation—cell staining—mounting—cell observation and counting." Fang Ziye swallowed back slowly.

The answer was slow, but precise.

"How does the experiment work?" Yuan Weihong returned the shoes to Fang Ziye.

"The invasion experiment is to put the chamber into the culture plate, the small chamber is called the upper chamber, the culture plate is called the lower chamber, the upper and lower culture medium are separated by a polycarbonate membrane, the upper chamber is added to the upper chamber, and the lower chamber is added to the lower chamber. Cells are planted in the upper chamber, and due to the permeability of the membrane, the components in the lower culture medium can affect the cells in the upper chamber, so that the effects of the components in the lower culture medium on cell growth, motility, etc. can be studied. ”

"But when the tumor cells are starving, they will definitely try to drill into the lower culture, and the number of tumor cells in the lower culture represents the ability to invade."

"It's the same as in high school, whoever is hungrier will run faster, everyone is equally hungry, whoever runs fast will eat first." Fang Ziye also made an analogy.

The corners of Yuan Weihong's mouth were crooked, although he was blocked by a mask, his eyes were entangled: "You will have no friends like this." ”

"Master, we are masters and apprentices, and we don't need to be friends." Fang Ziye grinned, knowing that he had passed this hurdle and would not continue to be criticized by Yuan Weihong.

"Teacher and friend, you shouldn't take these four words seriously, right?" Yuan Weihong's tone was full of jealousy.

People who have not soaked in the laboratory don't understand Yuan Weihong's hatred for people like Fang Ziye at this moment.

you, why don't you have to suffer the beating that the cell experiment brings you, one is accurate, one is accurate, the tumor cells are your relatives?
