Chapter 723 (1/2)

In the afternoon, Guo Xiang and Li Yuanhang went to catch some mice, put them in cages, and brought some wooden frames to put them in cages.

Then fully disinfect the laboratory, wear protective clothing and inject HIV virus into the mice.

When you come out again, the doors and windows are locked. No one can enter here without permission.

The worn protective clothing shall be placed in the basket on the corridor outside the office and reused after being cleaned and disinfected by the school workers.

The life span of HIV virus in a dry environment in vitro is very short, only a few minutes, and it is extremely resistant to high temperature. It can be killed by more than 70 degrees of water, or it can be easily killed by direct irradiation under ultraviolet lamp.

However, if it can survive for more than ten days in the laboratory culture medium, or it can survive for several days in the body fluid and blood, it cannot leak out with liquid.

After that, Guo Xiang began his laboratory life.

Do some data analysis before the mice don't get AIDS.

Life is in order.

Soon it was November, and the weather in Beijing had begun to get cold.

This weekend, Guo Xiang rested at home. The two small groups put on cotton padded jackets. The whole person was round and cute.

The twins were chasing little Q in the yard. Suddenly there was a knock on the door outside.

Little Q barked at the door and the twins stopped.

Guo Xiang went to open the door and saw Zhang Ling standing outside with a smile. Beside her was a tall, thin young man.

”Sister in law!” Zhang Ling shouted.

”Lingling is coming, come in!” Guo Xiang smiled, called Xiao Q and tied it to the side.

”Hello!” The man on the side greeted Guo Xiang with a smile. His accent was a little strange.

”Hello, Hello, please come in!” Guo Xiang smiled and let people in. He pulled Zhang Ling and asked in a low voice, ”is this your object?”

”Yes!” Zhang Ling nodded, a little shy, ”I met abroad before.”

”ABC?” Guo Xiang asked, no wonder the accent is strange.

”What is ABC?” Zhang Ling asked.

”Er...” Guo Xiang said. May this statement be available in future generations“ Are Chinese born abroad, Chinese of rice origin? ”

”Yes, how do you know?” The man was surprised.

”I can tell by the accent.” Guo Xiang said.

”That means I don't speak Chinese well.” The man looked a little annoyed.

”No, it's already very good, but people who don't grow up in China inevitably have a strange tone. It's very normal.” Guo Xiang said hurriedly.

”Introduce it!” Guo Xiang said to Zhang Ling.

”Oh, this is my object, Martin. I met him when I went to the United States to communicate. Since then, there has been correspondence. Recently, his company in the United States has set up an office in China, so he came here to work, and then we were the target. ” Zhang Ling said.

He also said to Martin, ”this is my cousin, Guo Xiang, a graduate student from Beijing Medical University, and now a doctor in the cancer hospital.”

”Hello, nice to meet you!” Martin learned some Chinese, but his pronunciation was strange.

Guo Xiang couldn't help laughing, ”come in!”

The two small groups looked at the guests curiously. Guo Xiang said, ”call your aunt and uncle!”

”Good aunt!”

”Hello, uncle!”

The two little dumplings shouted and ran inside, shouting, ”Dad, Dad, guests!”
