"You ask first." Director Mei gave in, but felt it was inappropriate, so she couldn't help but add, saying, "Director Yuan, Yang Rui doesn't know that you have done scientific research, this..."

"I understand, I understand." Director Yuan smiled with great majesty as a superior, and said, "I just read and not talk. Let's go back, I will nag you again."

"You are joking. At that time, I will put on the table and invite experts to come and listen to you explain and analyze it to us." Director Mei felt a little relieved when he saw that Director Yuan finally knew what he invited him to do.

He wanted to understand the situation in the laboratory, but he didn't want to offend Yang Rui.

In a moment, the two of them registered at the doorman's office and entered the laboratory.

Director Yuan looked around, still disgusted with his face and said, "This laboratory is just an old factory, right?"

"It used to be a warehouse." Director Mei replied in a low voice.

Director Yuan shook his head and said, "This is not possible. Foreign laboratories, not to mention any advanced instruments, they must first do the infrastructure well. I see that all the paint on the top has fallen out, and other paints have fallen down, which will affect the experiment."

Director Mei smiled and said, "No."

"Why can't you? Those who do experiments need to pay attention to all these."

"I guess I still have no money."

"Didn't you donate money to them? Where did the money go?"

Director Mei was a little surprised and said, "Do you know this?"

"Who doesn't know?" Director Yuan smiled and said, "China Animal Husbandry Corporation donated millions in one go, and everyone in the circle was watching."

Director Mei was a little nervous when he said this sentence.

He looked around and couldn't help but feel that the infrastructure was too outdated. However, thinking about what Yang Rui said before, Director Mei explained on his behalf: "It is said that many steps for embryo transfer of this cow have to be done on site. The environment of the ranch is worse than here, so there is no need to spend a lot of money to renovate the laboratory."

"That's right." Director Yuan thought about it for a moment, nodded slightly, but still disliked his face, and said, "Actually, it's a word, poor. Our country has poor conditions and lacks funds. This is an objective condition. Under the constraints of objective conditions, it is not easy to do research. So... instead of learning from foreign laboratories for embryo transfer, it's better to do some simple research, don't you think?"

Director Yuan's words were pleasant to hear in the first half, while Director Mei was a little reluctant.

However, the two had already entered the laboratory, so he could not argue with Director Yuan now. He could only nod in depression and said, "Here, the one on the right in front is Yang Rui."

"Such young."

"Yes, I'm only 22 years old this year."

"I'm only 22 years old, and there's a laboratory." Director Yuan said twice, "When I was 22 years old, I was still teaching below. I searched all over the county town and couldn't get a bottle of concentrated sulfuric acid."

Director Mei nodded again with a smile, then greeted the back in front and said, "Director Yang, I'm here again."

"Yo, Director Mei." Yang Rui turned around and looked at Director Yuan, and asked with a smile: "What is this?"

"Director Yuan is the leader of our Science and Technology Committee. I said it yesterday. Today I will come to see our laboratory." Director Mei tried to put it lightly.

Yang Rui smiled in surprise and said, "This is the leader's inspection..."

After saying a few nice words, Yang Rui did not make any move to the leadership inspector. After all, he had no affiliation with the Science and Technology Commission.

"Director Mei, Director Yuan will give you the reception." Yang Rui did not have a deputy like Xu Zhengping in the genetic engineering laboratory, so he simply threw it back to Director Mei.

"No, I'll take a look next to you and learn about your work." Director Yuan came over to see Yang Rui sitting on the experiment. He found a chair and sat down and started to observe.

Yang Rui was a little confused, but he still worked as usual.

He has done the part that provides primers to PCR, and this work cannot be learned by looking at it with the naked eye.

In fact, most experiments are not something you can learn with your eyes. Not to mention those complex chemicals, it makes people unable to distinguish types, content and proportions. Most of the time of primer design is based on luck.

The so-called primers are the medicine primers in PCR reactions.

To make PCR work, you must first use primers to seduce the required DNA fragments.

Therefore, primer design is a key step in the successful amplification of PCR. Good primers can not only avoid the generation of background and specific objects, but also identify genomic templates, etc.

However, primers are artificial, just like drug leads, and are always hard to come by.

In the 21st century, primer design was a relatively simple task, not only with common genes for reference, but also with a large number of design templates, and even three huge international nucleic acid databases used to query corresponding information resources.

Of course, there are also corresponding primer design software available.

Even so, most scholars will not design primers themselves because the work is cumbersome and professional, so they would rather find a professional company to outsource the work.

Unless you are at the forefront of the industry and are unwilling to reveal the breakthrough points and focus you are exploring, someone will design primers themselves. Of course, there are still those who cannot afford funds, and old-school scholars will do the same.

By 1985, Yang Rui naturally couldn't find any useful primers.

In fact, he could hardly find anything. Not to mention primer design software or corresponding nucleic acid database, he would not even think of one as the simplest general template.

The current PCR research is in full swing - naturally it is not a competition for PCR itself, but a competition to utilize PCR.

It's like when X-ray first appeared, a large number of scientists came up with their own research fields and thought of ways to use it. So everyone rushed to do it, at least, to get the time to make simple parts first.

There is no easier way to brush your face and influence factors than this.

In this fierce competition, you cannot expect kind-hearted scholars to publish the primer templates they have worked hard to make. Even if there is, it is usually an incomplete part.

Fortunately, Yang Rui himself designed primers, and with the support of various documents, he was qualified to start the job.

Of course, during the time of designing PCR, Yang Rui had to make some primer templates, but it was not possible to use it on the subject of gender identification.

He even had to start with the gene sequence of the cow.

This actually involves the genome project. The goal of the Human Genome Project is to sequence every gene in the human genome, like a map, and mark it out. Part of the function is to facilitate running PCR.

And in 1985, there was neither human genome plan nor cattle genome plan.

Any unit or individual who wants to know which gene is, sequence it yourself.

This is actually not particularly difficult. The human genome is composed of 3 billion base pairs, so it took a lot of time, manpower and money. The core sequence of a specific gene of the SRY sequence required by Yang Rui, even in the 1980s, only costs tens of thousands of yuan.

Of course, there are very few laboratories that can do gene sequencing now. In China, Yang Rui's ion channel laboratory is also the one in Yang Rui.

The Ion Channel Laboratory has set up a special research team a long time ago to do a lot of gene-related research, so that they can do a separate project and do a special gene sequencing. It is not very difficult in itself.

If other laboratories have requirements, they naturally need to negotiate and arrange time. Yang Rui has requirements. As long as the corresponding funds from the genetic engineering laboratory are allocated to the ion channel laboratory, the results will be easily obtained.

It was also on this basis that Yang Rui began to design primers.

I saw that he worked on paper most of the time, and he worked with bottles and jars for a small part.

Director Mei was dizzy when he saw it, Director Yuan was sweating on his head.

Director Yuan knows PCR instruments and understands the principles of PCR. He has also used PCR instruments, but that's all.

Director Yuan returned from the UK more than a year ago. At that time, PCR was made by Yang Rui, so Director Yuan did not have any contact with PCR or its use abroad.

When he returned to China, Director Yuan didn't work on the front line for a long time. Although he maintained the tradition of reading journals and often going to the front line, he really didn't know much about emerging PCR.

Of course, if Yang Rui uses PCR normally, it will be no difficulty for Director Yuan. It is nothing more than an instrument that is more troublesome than an X-ray machine. For scientific researchers, it is not as difficult as a rice cooker.

However, when Yang Rui started designing primers, Director Yuan caught him blindly.

Most scholars who understand the general knowledge want to catch them blindly.

Under Director Mei's long-term look, Director Yuan felt even more embarrassed.

"Let's go back." At noon, Director Yuan couldn't wait to walk out of the laboratory.

Director Mei quickly followed and asked in a low voice: "How are you watching? Are their progress going to be a result?"
