Chapter 29: Biological scar cream

　　　　 "hiss—"
"what--"
　　 "気持ちいい"
　　 After eating the apple, Zhou Wen immediately refreshed, his face was radiant, and all his fatigue was wiped out.
　　 He once again devoted himself to DNA extraction.
　　Practice makes perfect. With the continuous extraction, Zhou Wen's speed is getting faster and faster.
　　 An average of 2 hours to extract DNA from one strain.
　　 When the sun was bright outside, Zhou Wen finally extracted all the DNA of the seven raw materials needed.
　　 Looking at the DNA samples in the ice box, he felt a sense of accomplishment.
　　 The first time I extract plant DNA, it can be so perfect. Who else is there?
　　 After being happy for a while, a faint sense of fatigue came.
　　 From yesterday morning until now, he has been busy for 24 hours, and he has hardly stopped to rest.
　　 Let's go for a while.
　　He put the DNA in a sterile box and sent it to the PCR laboratory on the fifth floor.
　　 To prevent someone from ruining him after work, he also wrote a note on the box.
　　 Then he took a luxury taxi and went straight to the school.
　　 After returning to the dormitory, he straightened the body without brushing his teeth or washing his face.
　　 slept until 12 noon, opened his eyes, there was no one in the dormitory.
　　 went to take a bath and resurrected with blood.
　　 Then I went to the cafeteria to eat alone.
　　 Halfway through the meal, he suddenly remembered that yesterday's box had not been opened yet.
　　 Opened the system inventory, a dark treasure chest was lying quietly inside.
　　 Clicked, the treasure chest appeared in front of you, [Excuse me, open the box now? whether】
　　 Zhou Wen took a deep breath, with great expectations, he chose [Yes]
　　 The black iron treasure chest opened slowly, and a green sheepskin roll appeared inside.
　　 When Zhou Wen looked at it, he was suddenly excited. This look was the prescription.
　　 It's really good, a reminder box pops up in front of you, [Congratulations, get the bio-type scar cream formula×1]
　　 "Good stuff, good stuff~" Just looking at the name Zhou Wen makes me excited.
　　 When a person grows up, he will always experience some bumps and bumps, leaving some ugly scars.
　　 There are also burns, scars after surgery, etc.
　　According to modern people's love of beauty, if biological scar cream can really eliminate all kinds of physical, biological, and chemical trauma marks, then the value of this formula is simply inestimable.
　　The black iron box that opened up wasteland is really different, not in vain for his hard work these days.
　　 was excited for a while. He was just planning to learn the formula, but then he thought of the rice aphid experiment, which requires a lot of points to speed up the progress of the experiment. At this time, you can't just waste points.
　　 Then he looked at the experience value, it was already 1,000, and it was ready to be upgraded.
　　 glanced at the subject catalog and found that there is actually one more branch [Botany]
　　 After two glances, he withdrew his gaze and turned his gaze to Biological Immunology.
　　This subject is the most difficult in the entire biological sciences. It can also be seen from the experience value that other subjects have more than 100 or even 200 starting experience points, but biological immunology has only 50 points.
Because there are too many subjects involved in immunology, for example, which groups of human cells are, how they are differentiated, what genes are regulated, the characteristics of metabolism, what changes occur after infection, what drugs should be used, what are the risks... …
　　 There are countless subjects in biochemistry, pharmacy, virology, and oncology.
　　 So the system introduced biological immunity is: it lets you know the mystery of life!
　　 One can imagine, how difficult is this subject?
　　 Of course, once you master or even master immunology, you will definitely become an excellent doctor. Because you understand the principles of treatment, not blindly following experience.
　　 Zhou Wen chose to upgrade immunology.
　　 In the next second, countless biological immunological knowledge, like a stream converging to the sea, stuffed his brain into his brain, and then those half-understood questions became suddenly understood at this moment.
　　 He knows how human cells differentiate and what genes regulate them.
　　 also knows the characteristics of metabolism, changes after infection, and drug application.
　　 These have become indelible knowledge in his memory.
　　 Zhou Wen feels very comfortable. The knowledge of biological immunology is a supplement to biochemistry and pharmacology, which gives him a clearer understanding of biology.
　　 Of course, there is still a long way to go before being proficient in immunology.
　　……
　　 After eating, Zhou Wen hurried to the hospital.
　　 Just arrived at the school gate, the phone rang, and when I took it out, it was an unfamiliar number in Jiangzhou.
　　 "Hello, hello, who?" Zhou Wen answered the phone and walked toward the school gate.
　　 There was a sweet female voice on the phone, "Me, Xu Shuangyu."
　　 Zhou Wen: "Hey, why would you call me?"
　　Xu Pisces said uncomfortably: "Did you forget your eyes when you go out, so you can't see it as a big person?"
　　 "Where?" When Zhou Wen heard this, he stopped and turned his head to look around. As a result, under the shade of the tree diagonally opposite, he saw Xu Pisces wearing a baseball cap.
　　 is wearing a black and white striped long-sleeved shirt and straight-leg jeans. It is refreshing and simple. It exudes a fresh and natural atmosphere from the inside out, creating a beautiful picture.
　　 Zhou Wen hung up the phone and stood there waiting for her to come.
　　 Xu Pisui held his head high, his expression clearly said, come here!
　　 Zhou Wen looked down at the phone time,
The meaning of 　　 is very clear. I am very busy. If you don't come again, I will leave!
　　 The master moves, what he pays attention to is a momentum.
　　 Obviously, Xu Shuangyu is no better than Zhou Wen, who has no desires.
　　 When Zhou Wen was about to leave, he still came over.
　　 Xu Pisui raised his head, his face stinky and said, "Will you die if you walk two steps?"
　　 Zhou Wen smiled and said: "Since you won't die, why can't you come?"
　　 Xu Shuangyu opened his eyes wide and said: "I am standing in front of you, can't you see?"
　　 Zhou Wen: "Then it will end, you are here, what am I doing?"
　　 Xu Pisui's fragrant cheeks were shaking, and his eyes looked back at the flow, like a pretty Jiangnan woman, but with a trace of stubborn ripples, with the charm of a northern daughter.
　　 Xu Pisui grinned the white teeth and asked, "You have been a single dog for four years in college, right?"
　　 Zhou Wen: "How can you see it?"
　　Xu Pisces: "A love quotient as low as you can find a girlfriend unless the sun comes out from the west."
　　 Zhou Wen smiled, "You are wrong, I don't fall in love, it's not that I can't find a girlfriend, but I don't want to fall in love because..."
　　 Before he finished speaking, he turned and left, because he knew that Xu Shuangyu would follow up to hear the reason.
　　 As expected.
　　 Xu Pisui followed by and asked, "Say, because of what?"
　　 "Because I can't afford it."
　　 "嘁"
Xu Shuangyu laughed disdainfully, "I don't have the ability, but blamed the the girl. Don't all the boys with bad family conditions have girlfriends? Not necessarily? After all, your EQ is too low. , So no girl likes you."
　　 Zhou Wen: "You are right, I have a low love quotient, and I have no girls to like~EbookFREE.me~ alright?"
　　 "It was originally."
　　 "Let's do this, I have something else, let's talk back~"
　　 After speaking, Zhou Wen left in a hurry.
　　 Xu Biyu looked at his back, wrinkled his nose and snorted, then turned back to the original path.
　　 After walking two steps, she suddenly stopped again, and looked back, Zhou Wen's figure had disappeared.
　　 "Strange, why do you always meet this wooden man these days?"
　　 Xu Shuangyu muttered in his heart, then lifted his leg and left.
　　 After Zhou Wen arrived at the testing center, there was no delay in one minute, and he immediately started PCR amplification.
　　Different from DNA extraction, PCR amplification can do multiple samples at the same time.
　　 Zhou Wen prepared 7 plant DNA samples one by one.
　　 After getting on the PCR machine, he didn't stay idle either, but started to configure the biological enzyme preparations that needed to be added.
　　 Compared to plant purification, this is much simpler. It only needs to add various biological agents in strict proportion.
　　 At 4:30 in the afternoon, the plant DNA was amplified.
　　 I took out the samples one by one from the thermal cycler to see that the amplification effect was very good.
　　 Next, in accordance with the professional biotechnology pharmaceutical process, there are a series of complex preparation and disinfection procedures.
　　 However, Zhou Wen is a laboratory medicine and does not need to be marketed, so some steps are directly omitted, and some use simple procedures, such as purification, separation, concentration, and crystallization.
　　 This saved him more than 90% of his time.
　　 At three o'clock in the afternoon, the first batch of 12 biological analgesics was successfully formulated.
　　 There is the last step, in vivo experiment...
　　
　　Ps: Sorry, please...
