Chapter 1502 Gretel, Are You Giving This to Me or to Your Senior Sister?

Even if he could advance to level nine, Carlos could only work on the periphery of research. The hope for the advancement of the entire project still lies with high-level mages, especially the top mages.

Gretel finished today's transformation work and headed to the 12th floor. In Senior Sister Philby's exclusive research room, it was so quiet that you could hear the crackle of static electricity.

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..."

"Senior sister, what are you doing?"

Grete looked over. There was a loud bang, and he jumped back quickly and screamed:

"Sister, aren't you! How have I offended you! If you can't do it, don't shock me!!!"

"...I moved out the cut points." 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 eyes were closed, making people suspect that all her energy and energy were poured into the microscope. :

“However, after I moved out, I still couldn’t find the direction if I wanted to study it further.

I tried it repeatedly with the electron flow, and tried it back and forth. Every time the electron flow swept over it, it would move, but it always failed to unfold as it originally did..."

Can it move?

Senior sister you have found a way out!

"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?"

"Well……"

Grete retreated in defeat. Not to mention electrons, his mental power detection couldn't even detect atoms. Scanning chromosomes with a microscope and electron microscope, I can only see the results calculated by the electron microscope. God knows what the scanning process is like.

He took two steps back, then took another step to the side, stretching his head again and again, trying not to disturb the senior sister. Archmage Philby stopped paying attention to him and focused on the beaker in front of him:

"..."

no response.

no response.

Still no response.

From the side and behind, Grete could only see a piece of calm water with no ripples at all. As for the senior sister’s tense side face, her eyes that are almost burning with concentration, her masseter muscles that are bulging due to exertion...

Sorry, Grete 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 her 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 there's too much interference. …”

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...

Grete also sighed behind her. He could probably understand the senior sister's idea, 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. She can actually feel the components in the chromosomes.

But the medium is wrong and 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 proportion of the material, and the use temperature. For example, when running gel electrophoresis, Grete knows how to do this:

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 like Gretel can't tell his senior sister directly about this list of things, and then let her try it slowly. The problem is, he couldn'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 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, when 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 rub it out...

"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...

Gretel, who didn't want to be beaten, had to find another way. He patiently watched his senior sister's operations 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. Lay everything out one by one and start doing it carefully:

Add agar powder to boiling water, watch it melt, and pour half of it into the mold. Pause for a moment, choose a candied rose, cut off the stem and carefully put it into the mold, then pour half of the agar-agar water, put it into the ice magic circle, and wait for it to solidify...

oops!

There was too little agar-agar powder, and as soon as I poured it out of the mold, it broke immediately!

Come again! This time I doubled the agar-agar powder... Well, this time it was too thick and uneven, and the little bits of agar-agar powder inside didn't melt...

Come again! This time adjust the proportion of agar powder! Uh, what's wrong with the technique 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, she saw a row of snacks she had never seen before on the experimental table not far away.

Flowers with different postures are frozen in 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, strolling over and grabbing 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, the possibility is very slim.

After another scan, a lot of waste products were thrown away on the side of the experimental table. Broken, cracked, bubbles, slightly off-color, petals inside floating out of the pastries...

"Oh, I'll make something for Cerela."

Gretel stopped his hand and smiled at his senior sister as if nothing had happened:

"I have 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 am thinking of her and miss her. - Senior sister, look at this flower snack, how I did it Sample?"

"It looks okay, but it doesn't taste good..." Philby pondered. Young girls, one after another, like beautiful and good-looking things.

But Serira prefers delicious food, big fish and meat, fried, boiled and grilled. This kind of thing that is purely for the sake of appearance and has no feeling when you eat it one bite at a time may not be to her liking?

"As long as you're happy..." She swallowed her words and waved her hand casually. With a thought, he connected to the control center on this level 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 made 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...

"It looks so beautiful! Gretel, 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 Cerela ask him the second question? With a flick of his finger, an agar snack flew into his mouth. Dots of sweet-scented osmanthus float inside, making the entire pastry pale golden in color. A layer of honey is poured on the outside, giving it a fragrant aroma.

She carefully took a bite, chewed it twice, chewed it twice more, and then put the whole snack into her mouth with a "Ahhh" 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 on it and ate it, then turned to look at Philby:

"Senior sister... well, you should eat too!"

Silver-blue eyes stared straight at Philby, and if you don't eat, I will stuff it into your mouth. Philby couldn't resist the kindness, so she had no choice but to pick up one and bite it in small bites.

While tasting it, my mind wandered, holding the large piece of agar-agar snack in my hand, kneading, kneading, kneading. After rubbing it for a while, a ray of electricity flew out of the fingertips unconsciously and passed through the agar gel——

"Huh?"

Her eyebrows suddenly moved. When the current passed through, the petals inside the gel seemed to move slightly?

If this kind of gel is used instead of vacuum, water, 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 grabbed it and rushed to the experimental table without thinking. Grete followed the past and pointed out:

"I brewed it with hot water, 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's head turned to the left, then to the right, then to the left, then to the right. Blinking his eyes, he suddenly felt that the snacks in his mouth no longer tasted good:

"Grete! Is this gift for me or for your senior sister?"
