The two of them exchanged greetings, and Chen Ruobing noticed Tang Xin next to him and asked with a smile: "Who is this?"

"I just recruited an assistant Tang Xin."

Zhou Wen explained and then introduced to Tang Xin: "This is Director Chen Ruobing from the Institute of Drug Research. When I am not here in the future, you can consult Director Chen if you have any questions."

Tang Xin bowed slightly and said shyly: "Hello Director Chen."

"Yeah, hello~"

Chen Ruobing nodded with a smile, then asked Zhou Wen: "How did you do the purification of biotin and avidin?"

Zhou Wen: "This is simple, you can do this first..."

The two of them said while walking.

Tang Xin followed them step by step before walking towards the elevator.

I soon arrived at the lab on the fourth floor.

When they saw Chen Ruobing and Zhou Wen come in, the researchers inside greeted them one after another.

Many people even showed a look of admiration when they saw Zhou Wen.

Chen Ruobing took Zhou Wen to the locker room to change into sterile clothes, and then under Zhou Wen's step-by-step teaching, he began to purify biotin and avidin.

Biotin and avidin can not only be used in disease detection, but also greatly help the clinical reagent tests of drug.

However, biotin and avidin are still under test, so it will take some time to wait for clinical use.

At this moment, Chen Ruobing was really very grateful for the decision to let Zhou Wen enter the Institute of Drug Research...

The time in the laboratory is very fast, and four hours have passed in a blink of an eye.

Zhou Wen carefully extracted the purified streptavidin from the vessel and injected it into the test tube.

After putting down the extraction gun, Zhou Wen said, "Okay~ It's ready to use now."

Chen Ruobing picked up the test tube containing biotin, looked at the sticky liquid inside, and said happily: "Thank you~"

“You’re welcome~”

Zhou Wen walked to the pool and washed his hands while saying, "Remember, use it strictly according to the dosage instructions when using it. It cannot exceed 100μg at a time. If it is too much, it will not only be wasted, but the effect will not be good."

"I know~" Chen Ruobing put the biotin in the ice box and kept it. He came over and took off his gloves and washed his hands. "I'll treat you to dinner tonight."

"It's not necessary to eat~" Zhou Wen paused and said, "But you still have to kiss me and do me a favor. Let my assistant hang a name in the research institute, and pay my salary and insurance personally. Is it okay?"

"What's the problem with this~" Chen Ruobing agreed readily and said, "If it doesn't work, just hang it in the name of the research institute. You can help her hand over the hardware."

"No need. She is my personal assistant, so it's not appropriate to ask the institute to pay for it."

After pausing, Zhou Wen said, "Oh, there is another thing. Do you know where there is a house nearby..."

Ten minutes later, Zhou Wen, Chen Ruobing and Tang Xin stood in front of a beautiful four-story building.

This is still in the blood center.

This building is the staff dormitory of the Institute of Drug Research. Chen Ruobing has a single apartment here. Later, after her parents settled in Jiangzhou, she moved home, so she was always empty.

It happened to be lent to Tang Xin and lived there.

When I opened the security door, a musty smell that was not ventilated for a long time was coming.
