Chapter 1497 Gretel, are you giving this to me or to your senior sister?
Even if he can advance to the ninth level, Carlos can only work on the periphery of research. The hope for the advancement of the entire project still lies in high-level mages, especially the top archmages.
Grete finished today's transformation work and walked to the 12th floor. In Senior Sister Philby's exclusive research room, it was so quiet that the crackle of static electricity could be heard.
The senior sister sat in front of the microscope, staring closely at a small beaker in front of her, her face serious:
"No... no... still not..."
"Sister, what are you doing?"
Gretel looked over to see. There was an explosion, and he jumped back quickly and screamed:
"Senior sister, aren't you! How have I offended you! If you can't do it, don't shock me!!!"
"...I moved the cut points out." It had only been two days since we last met, and the senior sister's face was full of exhaustion, and even the circles under her eyelids made people suspect that all her energy and energy had been injected into the microscope. Among: turtle
“However, after I moved out, I still couldn’t find the direction if I wanted to study it further.
I used the electron flow to test repeatedly, back and forth, and every time the electron flow passed by, it would move, but it always failed to unfold as it originally did..."
Can it move?
Senior sister, you have found a way!
"Come on, senior sister, let me see how you do it!" Gretel became interested and moved directly behind senior sister. Philby turned back and rolled her eyes at him:
"See? What do you think? Your mental power is so delicate? Can you see electrons?"
"Uh..."
Gretel retreated in defeat. Not to mention electrons, his mental exploration could not even detect atoms. The chromosomes were scanned by a microscope and I could only look at the results calculated by the electron microscope. God knows what the scanning process was like.
He took two steps back, took another step to the side, and stretched his head again and again, trying not to disturb his senior sister. Archmage Philby stopped paying attention to him, and concentrated on the beaker in front of him:
"..."
no response.
no response.
Still no response.
From the side and back, Grete could only see a calm water surface with no ripples at all. As for the senior sister's tense profile, her eyes were so focused that they were about to burn, and her masseter muscles were bulging due to exertion...
Sorry, Gretel didn't look in this direction at all, couldn't see anything.
"well……"
A gentle sigh sounded again, disturbing the water in the beaker. Archmage Philby leaned back and held her head in both hands, feeling infinitely annoyed:
"I've tried everything I can...vacuum, air, nitrogen...pure water, salt water, the glucose water you made...it won't work if I put it in anything, it's either too lively, too stagnant, or it interferes too much …”
It cannot be stabilized in a vacuum, nor can it be stabilized in air or nitrogen. Most of the energy must be spent on lifting this small segment of chromosomes;
In pure water, the electron flow is very uncomfortable, and in salt water there is too much interference - probably due to its own charge, most of the electron flow is busy doing useless work...
Gretel also sighed behind her. He could probably understand what the senior sister was thinking, which was to use the push of electron flow to spread out this chromosome, unfold it, and reveal every component of it:
From this point of view, senior sister's mental power is indeed much more delicate than mine, and she can actually feel the components in the chromosomes.
But if the medium is wrong, there is no way. When it comes to media, materials are really a big problem. It is basically a matter of luck to find out which one can be used from the vast sea of liquids, solids, and gases.
Moreover, it is not only the type of material, but also the purity of the material, the ratio of the materials, and the use temperature. For example, when running gel electrophoresis, the method Grete knows is:
According to the size of the DNA fragments to be separated, use gel buffer to make an agarose gel of appropriate concentration;
Heat and melt, add fluorescent dye, mix thoroughly, and condense;
Pour the electrophoresis buffer into the electrophoresis tank, pour the loading buffer into the DNA sample, mix well, and slowly add the sample mixture to the gel loading hole;
Put on the electrode and run electrophoresis...
It's not that Grete can't tell his senior sister directly about this list of things, and then let her try it slowly. The problem is that he can't answer the following series of questions:
What are the ingredients of gel buffer?
What are the components of DNA loading buffer?
Which kind of fluorescent dye is used? Wait, does the current parliament have fluorescent dyes?
He can provide agar, but the purity of the agar is another matter. Agar used for bacterial culture media and agar used for gel electrophoresis are definitely not the same thing.
The concentration of the gel is another question...
Then, when applying the electrode, how many volts should be used and how long should it run?
——The most important thing is, why can we use this method to analyze what she needs?
Gretel couldn't answer any of these questions. Moreover, if he was asked to rub out a piece of tape with his bare hands when he didn't have what he wanted, he really couldn't...
"So why did you let me do this?"
I can’t answer this question, so I rashly provide a solution to senior sister, I’m afraid I’ll get beaten up...
Grete, who didn't want to be beaten, had no choice but to find another way. He patiently watched the senior sister's operation several times, quietly stepped back a few steps, and started tinkering on his own.
Agar powder, powdered sugar, clean water, various candied flowers, and molds. Arrange them one by one and start making them carefully:
Add agar-agar powder to boiling water, watch it melt, and pour half of it into the mold. Pause for a moment, select a candied rose, cut off the stem and carefully put it into the mold, pour another half of the agar-agar water, and put in the ice magic Formation, wait for it to condense...
oops!
There was too little agar-agar powder, and as soon as it was poured out of the mold, it broke immediately!
Come again! This time, double the agar-agar powder... Well, this time it is too thick and a little uneven, and the dots of agar-agar powder inside have not melted...
Come again! This time adjust the proportion of agar powder! Well, what is the wrong method this time? Why are there bubbles in the frozen agar!
Come again! This time the ice magic circle seems to have cooled down too quickly, and the agar-agar gel produced is a bit crooked...
Grete kept trying with his head down. When Archmage Philby finished today's experiment and turned around, he saw a row of snacks he had never seen before on the experimental table not far away.
Flowers with different postures are frozen in the crystal clear gel, still maintaining the appearance of budding or fully blooming.
This junior brother’s craftsmanship is quite good, but the problem is——
"Gretel! What are you doing?"
She asked as she strolled over and grabbed a snack.
The hemisphere, which is smaller than the palm of your hand, is trembling in the dish. The unknown flowers inside are reflected through the gel, making them look even more pitiful and cute.
Taking a casual bite, it seems to be a little sweet and a little sour, but whether it is sweet or sour, it is very light. If you want to be full on this, or even if you want to be three-thirds full, it is impossible. Quite slim.
After another scan, a lot of waste products were thrown away on the side of the experimental table. Broken, cracked, bubbles, some color deviations, the petals inside floated out of the snacks...
"Oh, I'll make some gadgets for Cerela."
Gretel stopped his hand and smiled at his senior sister as if nothing had happened:
"I've been busy these days and haven't been with her for a long time. Make something interesting to coax her and let her know that I'm thinking of her and miss her. - Senior sister, look at this flower snack, how I did it Sample?"
"It looks good, but it doesn't taste good..." Philby muttered. Young girls, one after another, like beautiful and good-looking things.
But Serira prefers delicious food, big fish and big meat, fried, boiled and grilled. This kind of thing is purely for appearance and has no feeling when you eat it one bite at a time. I’m afraid it’s not to her liking?
"As long as you are happy..." She swallowed these complaints and waved her hand casually. With a thought, she connected to the control center of this layer and quietly sent a message.
After a moment, the door to the laboratory opened with a bang, and Cerela ran in happily:
"Grete! Have you prepared something delicious for me?"
"Then, here." Grete pointed to the experimental table. Cerira's eyes lit up, and she rushed over and grabbed a small plate.
Hold it in your hand and look left and right, turn it around, hold the bottom of the plate with your fingertips, and turn it back and forth to look...
"It looks so beautiful! Grete, why did you think of doing this?"
"I haven't been with you for a long time. I'll make you some gifts - try it. Is it delicious?"
Why did Serela ask the second question? With a flick of his finger, an agar cake flew into his mouth. There were little osmanthus floating in it, which made the whole cake turn pale gold. A layer of honey was poured on the outside, and the aroma was fragrant. .
She carefully took a bite, chewed it twice, chewed it twice more, and then put the whole snack into her mouth with an "ah-oh" sound:
"It's quite delicious... but it smells like honey and flowers. This thing itself has no taste... Gretel! Is there any way to make a snack that is sweet throughout?"
"I put too little sugar. If I put too much sugar, it won't condense well..." Grete replied flatly. Cerira grabbed another snack with roses and ate it, then turned to look at Philby. :
"Senior sister...well, you should eat too!"
Her silver-blue eyes stared straight at Philby, threatening to stuff it into your mouth if you didn't want to eat it. Philby couldn't resist her kindness, so she had no choice but to pick up one and bite it off in small bites.
As he tasted it, his mind wandered. He held the large piece of agar-agar snack in his hand, kneaded it, kneaded it, kneaded it. After kneading it for a while, a ray of electricity unconsciously flew out of his fingertips and passed through the agar-agar gel——
"Huh?"
Her eyebrows suddenly moved. When the current passed through, the petals in the gel seemed to move slightly?
If this kind of gel is used instead of vacuum, water, physiological saline, etc., and the chromosome fragments she cut are placed in it, can these chromosome fragments be "spread out" in it?
"Grete! What is this thing called? Agar? How much do you have left?—Give me some!"
"I'll give you this bottle first. If you don't have enough, I'll get it later... This is made by Haishihua. It's very good. Senior sister, just use it. Don't worry about not having enough!"
Gretel responded and took out a large bottle of agar powder. Philby snatched it and without thinking, she rushed to the experimental table. Gretel followed and gave instructions:
"I used hot water to brew it, but it's not easy to brew it thoroughly. If senior sister heats it, she can consider other methods..."
"You can try different concentrations..."
Cerira turned her head to the left, then to the right, then to the left, then to the right. She blinked her eyes and suddenly felt that the snacks in her mouth no longer tasted good:
"Gretel! Is this gift for me or for your senior sister?"
