Chapter 174 172. Probably Dead
"It's really stingy." The driver waited for Qi Huiren and the others to get out of the car, and muttered a few words in dissatisfaction, "Isn't it just a bit of a motherfucker, as for scolding me all the way?" He still felt aggrieved.

"Old Qi, if you hadn't stopped me, I would have beat him up!" Dai Yonghui was still angry, "Let him see if I'm a sissy or not!"

"Okay, old generation." Qi Huiren comforted, "I don't know if you are a mother or not?"

"More than 10 years ago, we went to dinner at night. On the way back, we met a group of hooligans. It was you who went up alone. Cheng Jun and I were not beaten."

"Shut up!" Dai Yonghui was in a hurry, "What the hell, you two turned around and ran away. I can't run alone because I drank too much. When the police came, I was beaten and broke three ribs. .”

"You still have the face to mention this, you dog!"

"Then he also compensated you 8 yuan." Qi Huiren said with a smile, "I was so envious at that time."

"That's true." Dai Yonghui said, "I didn't expect there to be a rich second generation in it."

"At that time, the house price was only 5000 yuan per flat, so I made up a down payment backhandedly, and now it has risen to 4 yuan per flat, hehe!"

It was already noon at this time, and the gate of the university was full of students coming in and out, with carefree smiles on their faces, full of vitality, and the breath of youth rushed towards them. Qi Huiren and Dai Yonghui stood at the gate of the school watching for a while.

"What's wrong? Miss your college life?" Qi Huiren smiled.

"A little bit." Dai Yonghui replied, "At that time, I didn't have any worries. I was planning where to go with my girlfriend all day long."

"Where is Wenhui now?" Qi Huiren asked, Wenhui is Dai Yonghui's college girlfriend.

"I don't know, I haven't contacted her for many years." Dai Yonghui sighed, "We broke up with me less than half a year after she went abroad. She sent a few photos seven years ago, but we haven't seen anything since. "

"Maybe he's dead."

Qi Huiren

"Gao Feng!" Qi Huiren gave Gao Feng a big hug. "This is my colleague Dai Yonghui. He also made a copy of bevacizumab injection before."

Gao Feng and Dai Yonghui shook hands.

"Professor Gao, please take us to the laboratory." Dai Yonghui couldn't wait.

"I'm afraid it won't work." Gao Feng said with a smile, "We have to eat first."

"Yes." Hu Jiaran led everyone to a Xinyang restaurant, "Everyone said that this Xinyang dish tastes good, and the roast goose tastes very authentic."

When the boss saw so many people entering the store, he was very happy, "Quick, please go upstairs to the private room!"

"Boss, are you from Xinyang?" Hu Jiaran asked, "The dishes are so authentic."

"That's not great!" The boss replied bluntly, "In our corner, my business is the best!"

Everyone
"It's not easy for the boss." Gao Feng picked up a piece of roast goose, "A native of the Northeast, the roast goose is even better than Master Xinyang's!"

We drank a few glasses of beer and chatted with each other. "Why did you start making this generic drug?" Qi Huiren asked, "When was the last time you called?"

"Yes." Gao Feng replied, "I have been interested in this drug for a long time, and I have nothing to do recently. I just want to do the development of generic drugs, which is also of a practical nature."

What he said was simply not human, Dai Yonghui thought to himself, he has never seen anyone who used the development of generic drugs as a practice, what's wrong, the money is burning in his hands?
"What step have you reached?" He was very curious.

"If there is no accident, the multi-stage reactor will be cultivated the day after tomorrow." Hu Jiaran stood up and filled up the beer for everyone. "The current inoculation density in the 15L container is almost reaching the upper limit."

"Have you done quality control on the antibodies produced?" Dai Yonghui asked.

"Of course, we're not stupid." Hu Jiaran gave him a strange look, "If the purity is not enough, why carry out primary reactor cultivation?"

Dai Yonghui also felt that the question he asked was a bit silly, he just couldn't believe it.

A group of people came to the laboratory after eating.

The scientific research migrant workers inside were very busy, so Hu Jiaran called two people over and took out a part of the cell fluid from the primary incubator.

Dai Yonghui couldn't wait to verify it with his hands.

"Is this a project you are cooperating with the school?" Qi Huiren is very concerned about this, "There will be no disputes over the ownership of the results, right?"

"No, the results completely belong to our company." Gao Feng said, "The school only enjoys the right to profit."

Hu Jiaran took out the contract and showed it to Qi Huiren, "The laboratory is provided by the school, and the staff here are all employees of our company."

Looking at the results of the experiment, Dai Yonghui looked complicated.

"What's wrong? The old generation." Qi Huiren thought something was wrong, "Isn't it pure enough?"

"No." Dai Yonghui shook his head, "The purity is higher than I imagined."

"Good thing!" Qi Huiren was very happy, this trip was not in vain, maybe he picked up another hen that laid golden eggs.

After discussion, Dai Yonghui decided to stay here and wait for the results of the multi-stage reactor cultivation to come out.

This step is regarded as the final difficulty. Multi-stage reactor culture generally adopts the fed-batch culture method, adding feed medium at different culture stages, and finally harvesting the product at one time.

The bioreactor culture is divided into 4 stages, namely 20L, 50L, 200L, and 2000L. Each stage needs to add culture medium, and at the same time, different amounts of fermentation liquid must be added to meet the growth requirements of different stages.

20L 50L 200L为种子细胞培养阶段，培养的条件是36-37℃，搅拌的速度160rpm溶氧的需求为80%，总培养的时间为6天。

The 2000L reactor is the antibody secretion stage of the cell growth stage. In this step, at least 1500L of culture medium should be added, and the total culture time is 20 days.

Ren Yonghui noticed the difference at a glance, "Your cell culture medium seems to be different?" He picked up a test tube and looked at it, "I prepared it myself?"

"Yes, the effect is better than the previous one, about 10% higher." Gao Feng replied, "The next step is to apply for a patent."

"That's really good." Ren Yonghui praised, "If it has a wide range of uses, the annual benefits will be quite considerable."

"Old Chu, do you know what the new group of people are doing in the second laboratory?" Professor Li asked.

Professor Li, whose real name is Li Guoshan, is a professor and master supervisor of the Bioengineering Department of X Township Medical College, and also the director of the original second laboratory.

"I know." Chu Yunshan sat on the stool without lifting his head, "Isn't it what you said, doing generic drug development."

"It's bevacizumab injection." Li Guoshan said.

"Yeah." Chu Yunshan looked up at him, "And then?"

Li Guoshan went to close the door of the office, "I heard that they seem to be making it soon."

"No way?" Chu Yunshan's face was full of disbelief, "How long has it been! Who did you listen to?"

"They said it themselves. When I passed by, I heard someone say that this month is almost the end of the month, and I have to go back to Z state or something." Li Guoshan looked serious, "I guess they really have to make it. "

"That's great!" Chu Yunshan was very happy, "When they leave, let's move back as soon as possible. The equipment in the third laboratory is not good, and it is not easy to use at all."

"I didn't tell you this!" Li Guoshan said speechlessly, "Don't you have any other ideas?"

"What do you think?" Chu Yunshan was a little puzzled, "Old Li, what do you mean? Just say it."

"Do you think we can cooperate with them or something?" Li Guoshan asked, "If it is really done, Gao Feng can't handle such a big achievement by himself."

"Besides, we are all his teachers, and it's only right for a teacher to help his disciples."

"When the time comes, let him take the lead. The school will get a part, and we will get a part, that would be great!" Li Guoshan felt that he had considered everything thoroughly.

This old Li, I never found you so shameless before!Chu Yunshan was stunned.

"Hehe, that's not what I'm doing." He declined and said, "If my major isn't right, I won't get involved in this matter." After speaking, Chu Yunshan hurriedly left on the pretext of having something to do.

"It's really mud that can't support the wall!" Seeing his leaving back, Li Guoshan said disdainfully, "You can't even accept a fortune if I give you, waste!"

He planned in the office for a while, and then went out confidently.

"Professor Li?" Gao Feng was very curious, "Jiaran, do you know him?"

"It seems to be the original person in charge of our laboratory." Hu Jiaran had some impressions, "I came to see you once before, but I didn't come again when I saw that you were not here."

"Oh, let's meet then." Gao Feng greeted him out.

"Oh, heroes are born young!" Li Guoshan smiled all over his face, "I didn't expect our school to produce such outstanding talents as you. It's really not easy." He praised a lot.

"Thank you, Professor Li, for your compliment." Gao Feng also complimented the other person with his hand outstretched.

"I heard that your experiment has produced results?" Li Guoshan asked casually, "How long has it been? Your efficiency is really high."

"It's also luck." Gao Feng didn't think much about it.

Sure enough, Li Guoshan was overjoyed, "The project of the team I lead has just ended, and I have some time recently. If I can't do it, come over and help you."

While talking, he stared at Gao Feng's reaction, "I have also done drug generic development before, and I am very experienced, and I will definitely help you a lot!"

"There's no need for this." Gao Feng waved his hand, "We are almost at the end of the stage, and we have enough manpower for now."

"Oh, so, which pharmaceutical company do you plan to cooperate with after the drug is produced?" Li Guoshan said, "There are many powerful pharmaceutical companies in X Township, how many can I introduce to you tomorrow? All of them Those who are more familiar with me are trustworthy."

"No need for this." Gao Feng was very uncomfortable with his enthusiasm, "We have contacted a pharmaceutical company and are currently in contact."

This time Li Guoshan's complexion changed, this kid doesn't like oil and salt.

"Is the school involved in making this thing? Have you discussed it with me? How can you make random decisions by yourself! No organization, no discipline!"

The other party's sudden change of face made Gao Feng a little uncomfortable. Before he could speak, Hu Jiaran beside him was not happy.

"Who are you? Does it have anything to do with you?" Hu Jiaran was not used to him, "If you have nothing to do, hurry up, we are still busy."

Li Guoshan was so angry that he trembled, "How do you talk like a brat? Do you have quality? I might have taught you!"

Who are you talking about, the brat?Mr. Hu is very angry!

"We don't have a teacher like you." He deliberately made a disdainful expression, "I think you came here to pick peaches, you really think we are stupid!"

"You wait for me!" Li Guoshan left angrily.

"Jiaran, how can you talk to Professor Li like that?" Gao Feng said "dissatisfied", "If it spreads, it will be thought that we don't respect the teacher."

"My fault, I didn't control my emotions." Hu Jiaran quickly admitted his "mistake", "Next time I won't let him in!"

Li Guoshan came to Vice President Liu's office angrily, "What's wrong? Old Li" The latter looked at him strangely, "Who made you so angry?"

"It's not that Gao Feng!" Li Guoshan said to Vice President Liu evasively, "I passed by them today, and I just casually asked about their test progress, and they kicked me out like a wolf guard."

"You don't even know how ugly their words are!"
