The obstacles in front of her have collapsed, and as long as there is evidence to prove that Su Yuan is Gao Peng's daughter, the confidentiality agreement will have no effect on her.

Now the question has shifted to Su Yuan's identity, and if you want to prove Su Yuan's identity, it is a very simple matter.

Huaxin Technology has an office in Shanghai, call the office or contact the headquarters of Huaxin Technology directly, and ask the other party to fax a legally effective certificate. And this is not difficult for East China University of Science and Technology, so almost without thinking, the president's secretary made a phone call to the headquarters of Huaxin Technology in the name of the president's office of East China University of Science and Technology.

……

Haizhou Hi-Tech Park, the office of the chairman of the board of directors of Huaxin Technology.

Liu Zhenhua just finished answering Su Caiwei's call, his face was still full of confusion, Su Caiwei told him in advance without warning that he had an eldest daughter named Su Mengmei and a second daughter named Su Mengyuan, if someone came to ask, I hope to let him corroborate. Putting the microphone back on the base, Liu Zhenhua couldn't help but wonder about Su Caiwei's intentions.

As Su Caiwei's confidant, Liu Zhenhua worked hard with Su Caiwei in his early years in Su Meng Culture, and he has a good understanding of Su Caiwei's personality. He knew that this woman had always been shrewd, and she would definitely not give him a useless thing without a head.

There must be some purpose in this!

He placed one hand on the table, gently tapped the table with his fingers, and the sound of the knock was leisurely and full of texture, passing through the silence of the office, with this melody. Liu Zhenhua's thoughts gradually drifted away.

On behalf of Sumeng Culture, he has been in charge of Huaxin Technology for several years, and it can be said that he has witnessed the company's prosperity step by step. But let's be honest. Even as the chairman of the board of directors, he sometimes has a little confusion about the structure of Huaxin Technology and its board of directors.

For example, as a representative of Su Meng's culture. Why was he able to become the chairman of the board of directors of this company with only 10% of the shares? There is no reason for this, if it is said that the sandpiper and the clam compete for the benefit of the fisherman, it makes sense, but when you think about it, there is something wrong.

The two giants in the board of directors of Huaxin Technology are Tumanca Holding Group and Michel Modern Technology Group, if it is a competition between the snipe and the clam that they have to fight for the head of the blood, but the actual situation is diametrically opposite, the two giants are at peace with each other, and one actively participates in the management of the company. The other is quietly playing soy sauce on the sidelines. When it came to the final stage of voting, it was Su Menghua who won the seat, which taught Liu Zhenhua very puzzlingly.

He only knew that his predecessor Su Caiwei was on the board of directors on behalf of Su Meng Culture, and his superiority may just be a continuation of Su Caiwei's "convention".

Huaxin Technology was listed in 2002, Huaxin Technology is no longer a family-owned business, with the continuous influx of funds from all walks of life, the newly established board of directors has become the company's veritable highest authority! As another company under the old owner, Sumeng Culture has also silently grasped 10% of the shares in the change.

Liu Zhenhua is Su Caiwei's descendant and has been working in Su Meng's culture. Before settling in Huaxin Technology, although he knew that Huaxin Technology was also the Su family's industry, he didn't know much about this company, and he waited until the board of directors was established. Su Caiwei threw the burden to him after running it for a few years, and Liu Zhenhua gradually straightened out the operation of Huaxin Technology.

A company is a good company, but it's too big. The interior is too complicated!

Because Su Menghua is not the largest shareholder in the board of directors, Liu Zhenhua, as the chairman of the board of directors, will inevitably consider whether all parties can accept it when doing something. Take care of one and lose the other, and implement the mean. If it weren't for the fact that Bai Yan, the representative of the Michel Group, fully supported him in the general trend and formed an iron triangle with the chairman of the executive committee (CEO), he would have been a little aggrieved as the chairman of the board of directors.

He knew that if Su Caiwei was sitting in this seat, the situation would be very different.

This woman's influence on the board of directors is definitely more than a step higher than herself! I just don't know why she doesn't do the good chairman of the board of directors, but she wants to go to a middle school to be a math teacher, which is incomprehensible!

Just as he was pondering, the phone on the table suddenly rang.

Liu Zhenhua came back to his senses and lifted the microphone.

This call was made from East China University of Science and Technology, and the purpose was to ask Su Mengmei's identity. Liu Zhenhua was secretly surprised, thinking of Su Caiwei's previous phone call, he said in his heart that there was really some way.

After hanging up the phone, Liu Zhenhua thought about creating a document on the computer desktop, entered a few lines of text into it, and at the same time carried out a simple typesetting, after completing these, he notified the secretary to come in and print the document, stamp the company's official seal and fax it to East China University of Science and Technology.

……

Su Yuan's identity was confirmed by Liu Zhenhua, chairman of the board of directors of Huaxin Technology, and everyone present believed in the authority of this evidence. So Director Liu no longer hid it, and the dusty past was revealed little by little.

It turned out that after accepting Gao Peng's commission, the ancient head immediately started the research of related work. In the first month, the data will be collected, and then the plan will be drawn up and the experimental exploration will begin.

The title of the project is proposed to be "Research on the Relationship between Pathological Exploration and Genetic Abnormality of a Human Genetic Disease".

The topic was huge, and at first glance it was about some kind of human genetic disease, and at that time, it was quite difficult to start with genes. Fortunately, Gao Peng had some vague understanding of this kind of disease, so although Gu Tou was still skeptical, he still took the cell samples provided by Gao Peng for experiments.

Because of the huge amount of money invested, the venue, equipment, and personnel were no longer a problem, and the old head was very interested, so he recruited a group of undergraduate and graduate students to help him conduct experiments together. Speaking of which, the Department of Bioengineering at that time had a strong appeal, and the department also held a special meeting to discuss the provision of extracurricular credits and a certain amount of financial subsidies for those students who participated in the experiment.

This greatly stimulated the enthusiasm of the students, and for a time there were many applicants, who were personally screened by the old head. In the end, more than 40 students were selected to participate in the experiment.

As the saying goes, the flame of everyone collecting firewood is high, and so many people participate. The progress of the experiment was very fast. From June to October, just over four months. Gu Tou is responsible for the overall idea of the experiment and the determination of the experimental plan of each link, and other associate professors or lecturers such as Director Liu work with the students to carry out the specific implementation of the experiment.

By October, countless experiments had been carried out, but it was then that the old head ran into a technical problem.

That is, I don't know why it is common for newly cultivated cells to die after a certain number of generations. With the increase in the number of parental transmission generations, the vitality and adaptability of cells continue to weaken, and in the future, all the cells obtained through the early generation of amplified culture have died. The cells spread as if they were seriously ill, dying almost in patches, and eventually even the most basic experiments could not be carried out.

"All the cells are dead?"

As soon as Director Liu finished speaking, Su Yuan and Xia Lin looked at each other, they had never encountered this situation, even if it was an experiment done by "Xia Linfeng", at most it was only slow or not long, and all of them died, and it was a collective death. That's an exaggeration.

So far, Su Yuan has determined that the cells that Gu Tou studied originated from her, but if according to the results of his experiments, these cells will die collectively like an infectious disease after several generations, then how can she survive to this day?

The results of the experiment are contrary to reality!

Director Liu recalled: "Yes. At that time, we were all confused, and thought that there was a contamination of foreign poisons in some link. However, as the new cell samples arrived, we conducted detailed passaging tests. The result is still like that, when it reaches a certain algebra. The viability of the cells decreases and eventually they all die. ”

Later, we analyzed whether this phenomenon could be the genetic disease that Mr. Gao said, so we asked Mr. Gao. But the results obtained are negative, and the cell death should be due to another cause. ”

Su Yuan and Xia Linxiang listened quietly, and listened to Director Liu's next words: "At that time, Professor Gu put forward a guess, could it be that the cells have undergone subtle changes due to the nutritional conditions used for culture, you must know that the cells we are experimenting on are themselves carrying some kind of genetic disease, if the nutritional conditions of the medium are not suitable, will it further amplify this disease and make it harmful to the growth of cells?"

"Or is there an allosteric effect between the expressed protein and the substrate of the culture medium, which not only causes the protein to lose its original function, but even has a certain toxicity to the cell itself?"

Hearing this, Su Yuan nodded.

The so-called allosteric effect is that after a functional protein is combined with a substance, the morphological change occurs, and the function is also changed. If there is some kind of unfavorable factor in the culture medium, and a certain "button" is suddenly activated after the cells have multiplied for generations, an avalanche of death may really occur.

"If that's the case, even for similar reasons, we can't continue our experiments. Director Liu said with some emotion, "At that time, Professor Gu immediately decided to suspend the originally planned experiment, and he proposed that a suitable medium should be explored first!"

"This means giving up the previous four months of hard work, and the results of these four months are the first twenty-two experimental notebooks?" asked Charlene, with a deep groan.

Director Liu nodded: "That's right, after the original experiment was overturned, all of us who participated in the experiment shifted their energy to the construction of the culture medium and the optimization of the culture method. ”

"The process itself is not technically difficult, it is mainly reflected in the workload, fortunately, we have a large number of people, and the supply of equipment is sufficient, so it only took more than one month to complete under the urgent urging of Mr. Gao. (To be continued......)

PS: Regarding the allosteric effect, here is an example:

For example, the reason why hemoglobin has the ability to transport oxygen is because of the allosteric effect.

Hemoglobin itself is not easily bound to oxygen, and it has two α subunits and two β subunits, making a total of 4 subunits. When an oxygen molecule binds to heme iron in one of the subunits, the conformation (structure) of this subunit changes, and this subunit causes the other three subunits to also change, making it much easier for them to bind to the oxygen molecule than it is to bind to the first oxygen molecule, so that hemoglobin becomes easier to bind to oxygen. Conversely, once the hypoxic environment is reached, one of the subunits of the oxygen-laden protein loses its oxygen molecules, then it will drive the other subunits to become more susceptible to the loss of oxygen molecules, and the idea of hemoglobin recovers, and it becomes difficult to combine with oxygen again.
