Immediately afterwards, Shen Qi dislocated another mouse, which was healthy and used as a control sample to be compared with the infected mouse.

Remove the spleen of the control mouse, this organ is very small, and Shen Qi must be careful enough.

Once raw and twice cooked, Shen Qi weighed the spleens of the immune mice and the control mice and placed them in a petri dish containing cold Hanks's solution, and blew the lamp with a pipette to disperse the cells evenly.

The spleen is the body's largest immune organ, and it is the same as that of a human and a mouse.

Shen Qi filtered the splenocyte suspension of the rat through a 100-mesh stainless steel mesh, centrifuged to remove the supernatant and began to count the cells.

The lymphocyte fluid made from the spleen of white rats is similar to that of human lymph, colorless and transparent.

Because of the addition of agar, Hanks' solution, and DEAE glucose solution, the spleen lymphocyte fluid in front of Shen Qi's eyes was red, which was similar to the color of orange.

After the mixture is evenly solidified, it is allowed to stand for 15 minutes, and then placed in a warm bath at 37 degrees Celsius for 1 hour.

After the sample was removed, Shen Qi observed the results, and placed the flat dish under a stereomicroscope to count the number of empty spots.

A plaque represents an antibody-forming cell, and the number of plaques reflects the body's humoral immune function.

Shen Qi found that the experimental mice had more empty spots than the control mice, so he recorded the data and repeated the experiment, and within a few days 10 mice were exhausted.

There are still 10 rats left, Shen Qi did not move for the time being, he asked Yang Dingtian to take care of the rats, and reported to the school according to the procedure, saying that our center is doing routine animal experiments for scientific research purposes.

After arranging everything, Shen Qi flew to Stockholm, the capital of Sweden, in early December.

On December 10th, the Stockholm Concert Hall welcomed many big names from the Swedish upper class, including members of the Swedish royal family, senior political officials, business tycoons, and cultural celebrities.

The king, prime minister, richest man, and popular singers of Sweden are all here, and this scene is more grand than Sweden's National Day.

During his lifetime, Mr. Nobel was a very well-known scientist and a good financial manager, he had more than 300 patents, opened more than 100 companies and factories in more than 20 countries around the world, and amassed a lot of wealth.

Nobel never married and had no children, and he contributed most of his wealth to set up the Nobel Fund, which shocked the Swedish royal family at the time: this chemist is richer than the king!

Since the first Nobel Prize in 1901, the King of Sweden has personally awarded the Nobel Prize in memory of the rich scientist, a tradition that continues to this day.

Before the Nobel Prize ceremony, Shen Qi had already met the King of Sweden and had a few conversations.

The king was plain and approachable, with glasses and white hair, more like an old professor.

The Royal Stockholm Philharmonic Orchestra kicked off this year's Nobel Prize Ceremony with a song "Music from Dorotningholm Palace" on the stage of the Stockholm Concert Hall.

This was followed by a welcome speech by the President of the Nobel Foundation, and representatives of each committee introduced the backgrounds and achievements of the laureates.

One by one, the winners took center stage to receive their Nobel Prize certificates and gold medals from King Carl XVI Gustaf of Sweden.

The prize money for each prize is SEK 9 million, which is equivalent to 7 million RMB, and if there are multiple winners of a prize, they will split the prize equally.

Shen Qi and two physics professors at the University of Cambridge shared the prize money of SEK 9 million.

This year's Nobel Prize is similar to previous years, with scientists from universities in the United States and the United Kingdom winning almost all of the Nobel Prizes in the science category.

Shen Qi is the only scientist from an Asian university, and it is difficult to completely dissociate himself from the American academic community, and he still holds the title of honorary professor of mathematics at Princeton.

The university with the highest number of Nobel laureates in the world is Harvard University, and Princeton is ranked tenth.

In the second to ninth places, except for Cambridge and Oxford, the rest are all American universities.

This is also the pattern of the scientific community, and at the top are always the dozen or so well-known universities in Europe and the United States.

After the award ceremony, the guests moved to Stockholm City Hall for a gala dinner.

This time it was really a table full of Nobel laureates, Shen Qi's guests at this table were all kinds of Nobel Prize winners, the table was a long table, everyone ate and drank first, and there was a dance party later.

Canadian writer Margaret Atwood is in her eighties, she is a literary award winner, the old lady is in good health, wears dentures, eats some salad, and can drink two sips of white wine.

"Young man, you are amazing, you have set a record for the youngest person to win a Nobel Prize. The old lady of the literary award praised Shen Qi.

"Dear Margaret, I was looking forward to setting this record, but unfortunately, it wasn't me who set the record. Shen Qi raised his glass and toasted to the female writer.

Shen Qi won the Nobel Prize in Physics at the age of 27, and the youngest laureate in history was Laurence Pragg.

Laurence Prague was born in Australia and went to England with the famous physicist and his father, Prague Sr., to study at Trinity College, Cambridge.

In 1915, the father and son group Prague Jr. and Prague Sr. were awarded the Nobel Prize in Physics.

The award was given for the discovery of the Bragg's law of X-ray diffraction, which was later included in university physics textbooks.

Prague Jr. was only 25 years old when he won the Nobel Prize, and his record for the youngest has not been broken.

The scientific community sometimes has to fight for his father, and it is understandable that the old Prague, who was famous in the academic world at that time, was willing to take his own son to fly and win the Nobel Prize together.

It's really hard to break the record, Shen Qi debuted too late in the physics world, and he can't break the record held by Little Prague in his life.

"Anyway, the only Nobel Prize winner under the age of 30 so far is Lawrence Prague and you, Qi, you are the magic key. Yanni Stepgar, a French physicist in his fifties, works at the University of Cambridge in the United Kingdom, and he and one of his colleagues shared the prize money for this year's Nobel Prize in Physics with Shen Qi.

There is no shortage of Nobel laureates at this table, but there is only one Filipino Prize winner, Shen Qi.

Shen Qi is also quite popular, he has a special identity, he is in his twenties, he has two Tiffy Awards and Nobel Awards, and everyone likes to chat with him.

"Professor Stepgar, I've read your article, it's great, a toast to physics. Shen Qi raised his glass to the French physicist working in the UK.

"Hey, Strange, I've been to Princeton so many times that it's hard to see you. George Brown, one of this year's medical prize winners, from Harvard University, chatted with Shen Qi, who had been allies of the Ivy League and was self-acquainted.

"George, as far as I know, Princeton doesn't have a medical department. Shen Qi connected with Professor Brown, an American medical expert who won the Nobel Prize in Medicine for his research on immune mechanisms.

"The woman I love the most, in Princeton. Professor Brown said happily and bitterly, as he claimed he was currently single.

In fact, it is normal for people in the United States not to get married in their forties, Shen Qi asked with concern: "Which department is she in Princeton, do you need my help, George?"

Professor Brown gave Shen Qi a glass of wine: "She works in the mathematics department at Princeton and is the most beautiful woman in the world. ”

There are not many female employees in the Princeton Department of Mathematics, and Shen Qi learned the truth after a few casual sentences: "Is it her?"

Professor Brown said that she is who she is, and if he can't marry her, then he will marry science for the rest of his life.

This occasion is very international, Shen Qi talked with experts and scholars, writers, artists, economists and politicians from all over the world, exchanged business cards, and met many new friends.

When Shen Qi got married last year, he invited two Chinese Nobel Prize winners.

It is understandable that Shen Qi did not mix very well in the field other than mathematics last year.

If Shen Qi gets married this year, it is really possible to invite a table of Nobel Prize winners, all kinds of types.

It is impossible to get married again, Shen Qi's wife is already pregnant and will give birth next year.

Shen Qi sent some photos and videos of him and 10 Nobel laureates to Ou Ye, so that his wife could raise the baby with peace of mind, and properly watch the group photos and group activity videos of Nobel laureates.
