"What's wrong, what's wrong?" Professor Lassgur came to the second-floor lab door, and didn't immediately push the door inside.

The laboratory is a very dangerous place, and children who have done middle school experiments know that if the thermometer is broken, sulfur should be sprinkled immediately, because mercury will quickly volatilize in the air, and 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 Jiazitou. Methanol, formaldehyde, formic acid, formamide, and ethyl methanesulfonate are more powerful than the other. In the prefix of benzene, phenol is highly toxic and highly corrosive, skin contact is serious burns, inhalation is naturally worse; phenylmethyl sulfur fluoride is more powerful, can destroy the mucous membrane of the upper respiratory tract, poison the eyes and skin; benzo* acid is less toxic, but it is used more. Sodium azide is not only highly toxic, but also explosive, and extremely powerful, causing accidents in universities every year......

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

He is not only afraid of the danger of reagents, but he is afraid of many things.

The molecular genetics laboratory is not only for experiments on flowers and plants, but also for bacteria such as influenza, avian flu, plague or anthrax, etc., which also need to study its genetic problems.

In addition, it is inevitable that the laboratory will have some instruments containing radioactive materials.

If the instrument is broken and the radioactive material escapes out, it is really not too much to scream miserably, and the result is definitely much more serious than putting the picture without p in the circle of friends.

He waited quietly for five seconds, but no sound came from inside the door.

"Can you speak? If you can enter, you can knock twice, and if you can't enter, knock once. Professor Rasgul said as he motioned for someone to pick up the suit, and at the same time, he took a hook from the nearby lab and prepared to open the door to see what was going on.

At this moment, the second floor of the laboratory is almost as if a Resident Evil has erupted.

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

Immediately afterward, I heard a student say in a hoarse voice, "I'm fine, you guys come in." ”

Professor Rasgul breathed a sigh of relief, but he couldn't walk against the stairs.

After a while, students and teachers poured into the lab.

"What's the situation?" Professor Rasgul asked in a deep voice, his nervousness no longer visible.

"The experiment you told me to do, I finished. The students in the room probably realized that they had made oolong, and quickly explained: "Because the answer was unexpected, I didn't control my emotions......"

Not only was it 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, and all of them passed." ”

"All by what? Be clear. Rasgul gave a little vent.

The student stood up straight and whispered, "I use a PCR machine, the same machine you asked me to do the test, and I read the name on the manual...... In short, I used it to do four sets of experiments, according to Yang Rui's paper, that is, the method adopted by the inventor of PCR, strictly carried out, and copied two DNA strands respectively, and the results verified that the replication was successful. ”

"Did the copy succeed?" Rasgul repeated, suddenly realizing something, and asked, "All four sets succeeded?"

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

Rasgul let out a "yes" and looked intently at the experiment log.

He prefers the objectivity of the experimental record to the student's explanation.

Several other professors were also in general thought. They whispered about the experiment, and gathered around Rasgul to watch.

After a while, one sigh after another rang out.

"It's very simple. ”

"The logic is also very simple. ”

"No one had ever thought of doing this before?"

"I think someone must have done it...... It's not right, several of the techniques he used, you see the endonuclease Ц, are all improved in recent years, and it is really not so easy to try a few years earlier. ”

"Again, there are several key issues that need to be solved independently. ”

"The effect is also outstanding. Replicating DNA in this way can improve the efficiency a lot. ”

"We should be able to use ...... in the lab"

Several people gathered around to praise the PCR, and the praise was endless, although they made comments based on "this technology looks good" or "this technology has great potential", but they still talked happily.

After all, in this day and age, it is also very important to be lucky to come across a technology that "looks good".

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

Professor Evans endorsed Yang Rui again: "This author is a Chinese who did potassium ion function in "Cell" some time ago. ”

"The paper on the analysis of potassium ion channels by cloning mutant genes is also done by Chinese?" immediately a professor expressed surprise.

Evans spread his hands and said, "Same person, but different experimental group." ”

He clicked on the signed part and said, "It seems that Yang Rui did it alone." ”

"Experiments done by one person...... Hmm, it's a little lonely, isn't it?" said the man with a subtle laugh.

Several people laughed cooperatively for a few seconds.

Evans shrugged and said, "Maybe it's a crisis of trust, who knows, when I first saw this paper, I thought it was some kind of duplicate research, but I didn't expect that I couldn't retrieve the relevant paper at all, and he found a new world." ”

"At least an island of bounty. ”

"Speaking of islands, Japan is near China, and there are many Japanese scholars here today. I wonder if they have read about the relevant research, but the previous Warsaw Pact countries used to publish papers in their own journals, have they published similar papers?"

"Yang Rui wants to give a report at this conference, and if China had published papers before, he probably wouldn't have done it. Evans always felt the need to defend Yang Rui.

However, when he said this, several others agreed.

There is a lot of academic fraud, but smart people generally use smart methods, and the fraud that is easy to expose is not done until it is forced to do so.

"Does he want to give a presentation on the PCR machine?" asked Rasgul, after reading the paper.

Evans said casually: "Probably, he is still full of confidence in PCR technology." ”

"Of course, you have to be confident, if I make such a technical ......" Lasgul laughed, did not finish, but said: "Since the experimental results have not been discounted, it is also very good to introduce such a technology to everyone." ”

Evans nodded casually, he is a member of the organizing committee, and the nomination is nothing, just whether he wants to or not, whether it is necessary or not.
