Chapter 606

"What's the matter? What's the matter? " Professor lasqual came to the door of the laboratory on the second floor and did not immediately push the door in.

The laboratory is a very dangerous place. Children who have done experiments in middle school all know that if the thermometer is broken, sulfur should be sprinkled immediately, because Mercury will quickly volatilize in the air. There are such unavoidable dangerous accidents in middle school laboratories, let alone university laboratories.

Just pull a few commonly used reagents out, and there are few good things in the head of nail. Methanol, formaldehyde, formic acid, formamide and ethyl methanesulfonate are more powerful than each other. In the prefix benzene, phenol is highly toxic and highly corrosive. Skin contact is severe burn, and inhalation is more severe; Benzene methyl sulfur fluoride is more severe, can destroy the upper respiratory tract mucosa, toxic injury to eyes and skin; Benzoic acid is less toxic, but it is used more. Self employed proteinase K and propidium iodide are also things that can't be used and dare not be contaminated; Sodium azide is not only highly toxic, but also explosive. It is also very powerful. It causes accidents in universities every year

From the first floor to the second floor, Professor lasqual is doing psychological construction.

He is not only afraid of danger, he is afraid of more things.

The molecular genetics laboratory is not only doing experiments on flowers and plants. The pathogens of influenza, avian influenza, plague or anthrax also need to study their genetic problems. Although something goes wrong, it is not safe to ask through one door, but it is better to ask through the door.

In addition, the laboratory also inevitably has some equipment containing radioactive materials.

If the instrument breaks down and the radioactive material runs out, it's not too much to scream bitterly. The result is definitely more serious than putting the map without P in the circle of friends.

He waited quietly for five seconds. There was no sound in the door.

"Can you talk? If you can get in, knock twice. If you can't get in, knock once. " As he spoke, Professor lasqual motioned for the protective clothing. At the same time, he took a hook from the nearby laboratory and prepared to open the door to see what was going on.

At this moment, the second floor of the laboratory, almost like a biochemical crisis.

Just as the door was about to be opened, there were two "bang, bang" sounds inside.

Then, listen to a student with hoarse voice: "I'm ok, you come in."

Professor lasqual was relieved, but he could not walk by the stairs.

After a while, students and teachers swarmed into the laboratory.

"What's the situation?" Professor lasqual asked in a deep voice, and his expression could not see the tension.

"I have finished the experiment you ordered me to do." The students in the room probably realized that they had made an oolong, and quickly explained: "because the answer was unexpected, I didn't control my mood well..."

More than unexpected, the students wanted to shout: why didn't I think of it.

He looked back at the experimental table and said, "I did four sets of repeated experiments, and then verified them with electrophoresis. All of them passed."

"All through what? Make it clear. " Rasqual let out a little.

The student stood up straight and said in a low voice, "I used the PCR instrument, which is the machine you asked me to do the experiment. I read the name in the manual... In short, I used it to do four groups of experiments. According to Yang Rui's paper, which is the method adopted by the inventor of PCR, I carried out strictly and copied two DNA strands separately. The results showed that the replication was successful."

"Copy succeeded?" Rasqual repeated, suddenly aware of what, asked: "four groups all successful?"

"All successful, the operation is not very difficult, the fault tolerance rate is very high..." of course, according to the standard of the laboratory, after a brief explanation, he picked up the notebook on the desktop and said: "I made the experiment record, here it is."

Rasqual "en" a, focusing on the experimental records.

He preferred the objectivity of the experimental record to the explanation of the students.

Several other professors have the same general idea. They asked the content of the experiment in a low voice, and then they gathered around rasqual to watch it.

After a while, one sigh after another.

"The principle is very simple."

"The logic is simple, too."

"Nobody wanted to do that before?"

"I think someone must have done it... It's not right. Some of his techniques, such as endonuclease, have been improved in recent years. It's not so easy to try them a few years earlier."

"Also, we need to solve several key problems independently."

"The effect is also outstanding. Using this method to copy DNA, the efficiency can be improved a lot. ""We should be able to use it in our lab as well..."

Several people gathered around to praise PCR, and their praise was endless. Although they evaluated PCR on the basis of "this technology looks good" or "this technology has great potential", they still talked happily.

After all, in this era, if you want to meet a "look good" technology, you also pay attention to luck.

"Is it the research done by the Chinese?" Someone was surprised after reading the paper.

Professor Evans once again endorsed for Yang Rui: "this author is a Chinese who did potassium ion function in cell some time ago."

"The paper on cloning mutant genes and analyzing potassium channels was also made by Chinese people?" Immediately a professor expressed surprise.

Evans opened his hand and said, "the same person, but different experimental groups."

He ordered the signed part and said, "it looks like Yang Rui did it alone."

"An experiment done by one person... Well, it's a little lonely, isn't it?" This one said with a subtle laugh.

Several people cooperated and laughed for a few seconds.

Evans shrugged his shoulders and said, "maybe it's a crisis of trust. Who knows? When I first saw this paper, I thought it was a repetitive study. I didn't expect that I could not retrieve the relevant papers completely. He found a new continent."

"At least a fertile island."

"Speaking of islands, Japan is near China. Today there are many Japanese scholars. I don't know if they have learned about the relevant research. In the past, the Warsaw Pact countries used to publish papers in their own journals. Have they ever published similar papers? "

"Yang Rui wants to make a report at this meeting. If there were papers published in China before, he would not do so." Evans always felt the need to defend Yang Rui.

However, several other people agree with him.

There are a lot of academic frauds, but smart people usually use smart methods. The frauds that are easy to expose are not done when they have to.

"Does he want to report on PCR?" Rasqual finished his paper and asked.

Evans said casually: "probably, he is confident in PCR technology."

"Of course, I have to be confident, if I make such a technology..." rasqual laughed, did not finish, but said: "since the experimental results are not discounted, this technology is also very good to introduce to you."

Evans nodded at will. He is a member of the organizing committee. Nomination is nothing. It's just a question of whether he is willing or not and whether there is a need.
