When Qin Shuai passed by the research room just now, he heard the medical staff whispering that he couldn't find the antidote from Qin Shuai, and he didn't know whether this antibody existed.

He thought that since he wanted to help Song Hu, he hinted that he should be a little restless and take it one step at a time.

He knows that antibodies are proteins that have a protective effect produced by the body due to the stimulation of antigens. It is a large Y-shaped protein secreted by plasma cells and used by the immune system to identify and neutralize foreign substances such as bacteria and viruses, and is only found in body fluids such as blood of vertebrates, as well as the surface of cell membranes of B cells. Antibodies recognize a unique feature of a specific foreign object, which is called an antigen.

He himself is even claimed by everyone to have antibodies and can resist toxins, there must be, but they haven't tested it and haven't noticed it. So these days, when he was not fully responsible for being a full-fledged sergeant major in the army, he went to the military hospital whenever he had time, and then sat down to read their books on the subject with the help of their nearby library.

Qin Shuai was going to learn more about this knowledge and see if he could help Song Hu, when Song Hu shook hands with him that day, he seemed to be passing on some news to him. Maybe it was a code, and after a few taps on his finger, the toxin actually passed through. Song Hu could only stop.

Qin Shuai learned that the function of antibodies is closely related to their structure. The difference in the composition and sequence of amino acids in the V and C regions of the same antibody determines the differences in their functions. The V and C regions of different antibodies have certain structural changes, which makes them have commonalities in function. …… Recognizing and specifically binding to antigens is the main function of antibodies, and the structure that performs this function is the V region of the antibody, in which the CDR site plays a decisive role in recognizing and binding specific antigens. Antibodies come in monomers, dimers, and pentamers, so the number of days they bind to the epitope varies. The number of epitopes that the antibody binds to is called the antigen binding valence.

What they need to check out is that according to these theories, after the V region of the antibody is combined with the antigen, with the help of the C area, various antigen and antibody binding reactions can occur in vitro, which is conducive to the detection and function judgment of antigen or antibody, and can neutralize toxins, block pathogen invasion, and eliminate pathogenic microorganisms in vivo......

Although these are relatively long and difficult to remember for Qin Shuai who is in the army, he has the ability to never forget, so he still insists on memorizing these by heart, although he doesn't understand it for the time being, he believes that through his efforts and his love for Song Hu, he will definitely be able to help him in the future.

Qin Shuai went back confidently, while studying military robots, and studying antibodies during his rest. Let's see if we can make a miracle medicine that can help Song Hu and the soldiers infected with these toxins. Because some of them have been discharged from the hospital, but there will be some sequelae-like conditions, their hands and feet are numb and stiff. They must not be able to go to the battlefield for a while, and the toxin is contagious, so they are still in isolation when they return home.

Jiang Linda felt that Qin Shuai was too tired, even if he was able to work hard, the burden on his shoulders was too heavy. So she asked Xiaoduan and Qin Chuan, as well as herself, to share a little for him, because Qin Shuai had already instructed Xiaoduan and them to make military robots before, so they helped Qin Shuai as assistants in this regard, and it was beneficial to the army.

Linda is responsible for helping Qin Shuai in finding antibodies, and in fact, she is also helping the Song family. The Song family actually has some news about their father, and Jiang Linda knows it, but it may be inconvenient for them to disclose it. Or there are some instructions above for them not to say it, and there must be something to hide from them. Her father, innocently disappeared for no reason, in fact, they are all related to them, and Linda has not asked carefully over the years, because she can't ask. But if Song Hu had been saved, the situation would have been different.

When she told Qin Shuai these thoughts, Qin Shuai actually had this intention, and she didn't expect the two of them to hit it off, so they must work hard to find this antibody.

Since Qin Shuai can be safe and sound, he must have this kind of energy on his body, but Qin Shuai carefully recalled the things that Song Hu had beaten that day, so he hurriedly asked Jiang Linda what these gestures meant, but he didn't tell anyone else. I'm afraid it's a kind of magic password.

Qin Shuai recalled every detail, and then made gestures to her. Linda discovers that he is tapping on an address.

Because Linda had conducted some of this type of simulation training when she was in the Intelligence Department before, his gestures were actually some code codes from the Intelligence Department.

But the medical staff did not let Song Hu hold Jiang Linda's hand that day. So he could only hold Qin Shuai's hand and pass these things, he thought Qin Shuai knew.

Qin Shuai humbly asked Jiang Linda, and politely called her a master, joking and asking her how to identify these passwords.

Linda felt that Qin Shuai should encounter some situations, so she spoke bluntly and told him straight to the point and reminded him that if he learned it, he must not tell others again, otherwise once it is known by others in the future, Linda will definitely be implicated, and the intelligence department may punish her. She was not afraid of being punished, what she was afraid of was that the two people were far apart and were assigned to other places. It's something she doesn't want to do, too.

Qin Shuai wanted to relieve such a serious and embarrassing atmosphere, and said with a smile: "I can't imagine that my fiancée is thinking about me everywhere, I really found the right person, and today taught me so many fun ways to solve passwords, how can I thank you, otherwise you will accept this ring." ”

At this time, there was no one else in the house, Linda sighed, smiled and said that she reluctantly accepted it, in fact, she was willing to accept it in her heart, but she felt that she had not found her father yet, and she always thought about her children's private affairs, and always felt sorry for his old man.

Because she, like Qin Shuai, has hope, and there is always a feeling that her father is still alive and not far from them. Maybe it's floating in space, but whether it's dead or alive, you always have to see him, and Linda always has to say in front of her father that she has found someone she likes.

"And you don't always giggle, this cryptographic research is such a serious thing, you actually said it's fun, you must pay attention." Linda looked at him pretending to be angry.

Qin Shuai immediately grabbed her hand and put the ring on the middle finger of her right hand.
