A liquid medium, a solid medium.

There are cultured strains inside.

Jin Chengshan said very satisfied: "Study hard with me. If you perform well, I can consider saying a few words to you in front of Teacher Cui."

"Then thank Senior Jin." Zhou Wen said with a sarcastic smile.

Jin Chengshan smiled proudly and put the culture medium down.

The method used to extract plasmid DNA is the most commonly used alkali cleavage method.

Jin Chengshan started to operate.

The students next to them began to observe.

A lot of instruments are used here.

Centrifugal culture medium, filter, precipitate, shake, mix well, reverse the test tube...

Zhou Wen looked a little drowsy. These processes were very simple than preparing for enhancement agents.

Even the simplest H series enhancement agent is more than ten times easier than this process.

Zhou Wen mastered the preparation of enhancement agents, so he naturally looked down on these things.

Jin Chengshan's experimental process has been halfway through.

At this time, Jin Chengshan's face suddenly changed, but it quickly covered up.

"Kan Zeguang, come and continue the remaining experiments." Jin Chengshan said.

"The remaining experiment is not very difficult, so I'll leave it to you."

Kanazawa nodded and walked up.

However, Zhou Wen noticed something was wrong.

If this experiment is not problematic, there will be only a few dozen minutes left to complete, but there will definitely be frauds in Jin Chengshan who asks Kanzen to do it at this moment.

Kanazawa Miku was simple in mind and didn't notice it, so he took over the experiment and started doing it.

At the end, after the precipitate was dissolved in the TE buffer, Kanazawa Kuang took the test tube and put it into the refrigerator.

"It's over." Kanazawa Mitsuki breathed a sigh of relief.

The whole experiment took an hour.

Jin Chengshan laughed and said, "It's not bad, your skills are getting more and more skilled."

Kanazawa Mitsu smiled and said nothing.

"Have you asked about any strange smell?" a student asked.

Kanazawa Gwang sniffed, frowned, and said, "It seems like there is a strange smell!"

Everyone began to look for the source of the taste and finally locked in the refrigerator.

The strange smell comes from the refrigerator.

Jin Chengshan rushed over immediately and opened the refrigerator door.

I saw that the test tube placed in the refrigerator was foam inside at this moment, and the fine foam was gusping outward, emitting a strange smell of rotten eggs.

"No, clean it up quickly! The solution is broken!" Jin Chengshan shouted.

He covered his mouth and nose and stepped back.

There may be some toxic gases in this odor.

"It's not chlorine gas, right?"

None of them dared to go up.

"Kinazawa-Kun, it's all your fault. Did you get the wrong steps and cause the solution preparation to fail?" Jin Chengshan said angrily.

"It's impossible, I've always operated according to the regulations." Kanazawa Guang was shocked.

The foam was still gurgling.

But no one caught up.

"Ren Chao, why are you still standing there?" Jin Chengshan cursed.

"oh."

Zhou Wen walked over, put on gloves, took out the test tube, and poured the liquid inside directly into a special recycling barrel.

These odors will not affect him.

He even doesn't wear gloves, but this is a bit eye-catching.

"Who asked you to pour out the things?" Jin Chengshan started cursing again.

"This thing is no longer usable, why don't you fall down?" Zhou Wen asked back.

"This is something I have spent a few days preparing. Can you compensate me if you fall down?"

Jin Chengshan was fierce.

"The solution preparation failed because you set the wrong temperature when centrifuging after adding solution No. 3 to pre-cool, which led to the failure of the experiment. You are now placing the responsibility on others. What does it mean?"

Zhou Wen said coldly.

"What are you talking about?" Jin Chengshan's face changed.

"If it weren't for the fact that you had discovered that it would fail, how could Kanazawa Mitsuo do the experiment? Don't you just want to count the responsibility on him? Now you want to count the responsibility on me?"

Zhou Wen pressed step by step.

In the laboratory, everyone's faces changed.
