I'm so sweet after the divorce

Jiang Yanfeng helped him make the gel, Su Li was also extracted, and he sprayed his fiancé with alcohol once more to keep him away from him: "I'm going to add a sample."

Jiang Yanfeng had no choice but to watch from three meters away.

Su Li hadn’t done it a few times, and his movements were very clumsy. The blue mixture spread from the tip of the gun, and it didn’t get into the hole. He tried several times, but all ended in failure. Su Li was getting impatient. But I don't want to ask my fiancé for help, that bad man must be watching a joke.

Jiang Yanfeng really couldn't stand it anymore: "Let me add it for you."

"Then don't talk, try not to breathe, and don't pollute the DNA." Su Li said seriously.

Jiang Yanfeng took the pipette and said: "The diffusion is so serious, you can adjust the ratio of the sample to the loading buffer, and use one to two in the future."

Holding the wrist of his right hand with his left hand, he steadily injected six microliters of the mixture into the gel hole. He looked up at Su Li: "You do it yourself, slow down."

Su Li imitated his appearance, because of nervousness, her wrist shook a little, this time all the liquid went in, it was just that there were bubbles in the gel hole.

Su Li: "..."

Jiang Yanfeng was worried for him: "It's best to shoot in once."

Su Li's ears turned red, and his fiancé also realized that he had said something like a tiger and wolf, so he quickly shut up.

"I'm a little nervous, help me get the rest of the samples." When Su Li saw the pipette, some messy things would be staged in his mind.

Jiang Yanfeng had no choice but to add samples for him, Su Li said: "Use 80 volts of electricity, wait four to ten minutes."

Jiang Yanfeng: "It doesn't take that long, 110 volts, 10 minutes."

Su Li retorted: "But the senior told me to use [-] volts."

Jiang Yanfeng explained patiently: "Electrophoresis is just to prove whether you have extracted the nucleic acid. In the end, you only need to see the bands. Increasing the voltage only makes the nucleic acid move faster in the buffer, and has no effect."

"Oh."

During the waiting time, the two of them had nothing to say, Su Li stared at the blue sample solution in the buffer, and moved slowly from the end of Ningjiao, very slowly, wanting someone to kick him from behind.

Jiang Yanfeng took the initiative to care about the children's studies: "Can you do PCR?"

Su Li said: "My male god will teach me."

Jiang Yanfeng had nothing to say again, Su Li found that the word "male god" was a sharp weapon to shut Jiang Yanfeng up, as long as he mentioned it, Jiang Yanfeng's face was like a pool of stagnant water.

Twenty minutes later, there were a few faint blue lumps in the center of the gel, "Let's take it for imaging." Jiang Yanfeng said.

Su Li looked at the half-human nucleic acid imager, not knowing where to start.

Jiang Yanfeng asked casually: "Didn't your male god teach you?"

This sentence stepped on Su Li's tail, he frowned, and said angrily: "You asked me like this on purpose, why are you so mean?"

"So you still won't."

Su Li: "..."

"Wear gloves, take off the Ningjiao first." Jiang Yanfeng instructed him.

Su Li was in a bad mood, so he vented his anger on the fragile gel, and broke the gel with a heavy hand. He looked at the fragments in his hand regretfully: "It's too easy to break, what should I do."

Jiang Yanfeng: "It doesn't matter, put it together."

Su Li saw that the picture on the computer was pitch black, and only the hole on the side of the gel was white. He wondered, "What is this? I don't understand it."

Jiang Yanfeng was silent for a while, and told him: "You failed to extract, there is no product."

Su Li's shoulders slumped, his facial features wrinkled together, and he asked aggressively: "Is it polluted by you? Oh, I see, you deliberately changed the parameters of the electrophoresis, just because you didn't want me to get the product, you are bullying me Don't understand anything?"

Jiang Yanfeng hurriedly explained: "No...the voltage level has no effect on the detection, you really didn't extract the product..."

"You see, if I don't understand, just make up a reason to lie to me. You must have electrocuted the DNA with such a high voltage!" Su Li has already disregarded the common sense of biology, and being a troll doesn't need logic!

In short, he is the original sin, Jiang Yanfeng is very aware of this, he did not explain to Su Li, he calmed down: "Let's go to register first."

Su Li stood still and said, "Don't come here again."

"Su Li," Jiang Yanfeng said earnestly, "How could the experiment succeed once? What's more, you are a novice, so just think that I polluted your DNA this time. What if it fails next time?"

"You cursed me?" Su Li said.

"Okay, let's not talk about DNA, let's register first." Jiang Yanfeng completely surrendered.

Su Li didn't sit in the co-pilot this time, and ran to the back seat angrily. He really hates Jiang Yanfeng, and now he has to register for marriage with this person!

Su Li sent a WeChat message to Xiang Yunkun saying: DNA extraction failed, senior, can you come with me next time?

Brother Xiang: Didn't I take you to do it once?It's normal to fail, just try a few more times, and my success rate is only [-]/[-].

Seeing such an answer, Su Li felt disappointed like a tide. He still humbly begged the person he liked: I think my operation is still not up to standard. Can the senior come to supervise me? I invite the senior to eat meat crab pot.

Xiang Yunkun replied: Okay, on Tuesday night, I will teach you how to do PCR by the way.

A small firework bloomed in Su Li's heart, this was the only thing that made him happy today.

It takes more than an hour to get from the school to the Civil Affairs Bureau. The urban area is no different than the campus. There are traffic jams everywhere, and there are ups and downs from time to time. Su Li was a little tight in the chest in the laboratory, but now his internal organs are dislocated due to the bumps.

Jiang Yanfeng's car still had a faint scent of orange blossom, which was originally a soothing and pleasant smell, but the smell of motion sickness Su Li was disgusting.

He rolled down the car window and took a greedy breath of the outside air, but the air in the urban area was very dirty, his mouth and nose were full of gasoline smell, so he quickly rolled up the car window.

It's really strange, he doesn't usually get motion sickness, so why does he get so dizzy when he takes Jiang Yanfeng's car.

He and Jiang Yanfeng are really at odds, even his car is not compatible with him.

Jiang Yanfeng seemed to sense that Su Li was not feeling well, so he handed over a box of Yida with one hand, and said, "It'll be here in half an hour."

When Su Li chewed the gum, the car bumped heavily. Su Li's hand was placed on top of Jiang Yanfeng's. He felt burned, and the stress response made him withdraw his hand immediately.

In fact, Jiang Yanfeng's hands were very cold, with a thin layer of cold white skin covering the bones, the temperature difference between the two's hands was a little large, and Su Li would be irritated.

In order to avoid suspicion, Su Li took the chewing gum carefully without touching Jiang Yanfeng's long and beautiful fingers.

After the two of them received their certificates, Jiang Yanfeng suddenly said, wait a minute, there is something for you.

Su Li's face was full of question marks, what the hell was going on, she was very mysterious.

There was a pink box on Jiang Yanfeng's palm, and a pair of wedding rings lay on the black velvet impressively. The rings were wrapped with rose gold in the shape of a knot, gentle and firm.

Su Li didn't expect that he had prepared a ring, and his mouth grew wide in surprise. Of course, he wasn't overly sweet, and he didn't care about the ring, but just marveled at Jiang Yanfeng's seriousness in following the procedure.

Jiang Yanfeng held up his hand and wanted to help him put it on, but the ring was about to slip on his fingers, Jiang Yanfeng suddenly stopped and said, "It's inconvenient for you to wear it at school."
