Chapter 414

Friends who like to eat Chaoshan beef hotpot should have an impression of the instant boiled product of chest oil.

That's a fat film near the cow's heart.

And generally only large and fat cattle.

Many people like to take this chest oil as the most beautiful food. They must order it on the table, and the price is not very expensive.

A piece of chest oil was introduced into the mouth, completely welcoming the whole aroma of butter... Cough, deviated.

to make a long story short.

The four stage monster as like as two peas and the thunder crash, the material color is extremely white, and looks almost the same as that of the chest oil.

Yes, of course.

This is just an expression of appearance.

This unknown white substance is obviously two concepts with chest oil.

Back to the lab.

Although there is another substance that is obviously not so easy to analyze, almost all researchers from the forest to the ordinary researchers are very excited.

That's what scientific research is all about.

In the case of a pile of black boxes, I'm not afraid you won't change.

I'm afraid you don't move like standing water.

this moment.

Looking at this greasy white material, it is not very professional. Zeng Gucheng first opened various brain holes:

"Lao Lin, you don't think this thing is a worm egg?

Like in those science fiction movies, quietly run out of a ooze monster and hold your face? "

Lin Li pondered for a moment and nodded gently:

"Theoretically, it is possible, but the specific situation needs to be tested.

If it's some kind of biological egg.

We should be able to detect a certain degree of signs of life, and the components should also have a large amount of protein - unless it is not a carbon based organism. "

Then he looked at Wang Qiang and asked:

"Xiao Wang, do you have feedback on the marking solution?"

Wang Qiang Fei quickly glanced at the screen and shook her head:

"There was no sign of reaction, and the thermal imaging device did not detect any temperature change."

Thermal imaging equipment.

This word has been heard more or less in life, but I'm afraid not many people really know it.

actually.

Its accuracy is related to temperature resolution, also known as equivalent noise temperature difference.

This is also its technical core or basic support.

The lower the value, the higher the accuracy.

The equivalent noise temperature difference of ordinary thermal imaging equipment is about 50mk, and the professional second-generation optical detector is about 20mk.

Today, the military level is the third generation detector, which can reach 1mk.

The equivalent noise temperature difference of this thermal imaging equipment in the laboratory is only 0.2mk, and the temperature change in the range of 0.0004 degrees can be detected theoretically.

With this level of detection equipment and such a close distance, the accuracy of detection results is still relatively high.

Then Lin Li thought and ordered:

"Xiao Wang, let's start the component test."

Wang Qiang nodded:

"I see."

Looking at Wang Qiang returning into the closed operation room, Zeng Gucheng gave a strange look at the forest:

"Lao Lin, why did you let Xiao Wang do all these operations now?

I remember in the early years, the key link was you.

Why, suddenly life is full of enlightenment, no desire and no desire? "

Zeng Gucheng's remarks were obviously a joke among acquaintances. Normally, laughter passed.

But surprisingly.

There was a rare silence for a few seconds.

Then he opened his five fingers and put them in front of Zeng Gucheng.

It can be clearly seen.

At this time, there was no external force load, but the numerous little thumbs and ring fingers were trembling faintly.

In this case, operating the arm is likely to cause major problems.

See this scenario.

Zeng Gucheng was stunned, and his smile suddenly froze.

At this time, he remembered that the general director of the firewood camp was 64 years old this year.

Then he also touched the calluses on his hands. Yu Guang glanced at Zhuo Yuanxin around him.

Sigh:

"We are all old..."

At this time, Wang Qiang didn't know the conversation behind her. Her attention was all on the blood and meat samples.

Although this white tissue looks dead at present.

But considering that there were monsters whose flesh and blood were fried into blood mud. Wang Qiang and others still retained enough vigilance.

Firstly, the white lipids were analyzed by X-ray transmission.

It is determined that its basic properties are relatively stable and there is no internal chemical change.

The strange new sample was transferred to the observatory.

Soon.

A micron level sampling needle was controlled by Wang Qiang and gently 'bitten' a mouthful of white material like a mosquito's mouthpiece.

The sample volume collected by this sampling needle is small, only one tenth of a grain of rice.

Under poor light conditions, the naked eye may not be able to distinguish it.

But for the existing scientific and technological level, collecting such a sample is basically the same as collecting a piece of meat.

The extracted white substance was quickly placed in a container, and its image was synchronously projected onto the display by the macro camera.

Considering Zeng Gucheng's view of insect eggs, Wang Qiang first detected that naturally it was protein.

It was mentioned in the junior middle school textbook.

Biuret reagent is generally used to detect protein,

Because the peptide bond of protein can complex with Cu2 + in alkaline solution, it forms a purplish red compound.

However, this method belongs to macro verification and requires more samples for comparison.

And sometimes errors may occur.

Therefore, Wang Qiang chose another way:

Pull down target proteins were identified by mass spectrometry.

Pull down mainly uses highly purified and enriched bait proteins to capture target proteins with weak interaction or low abundance in cells.

This is also a firm way to improve efficiency.

Moreover, it can not only identify proteins, but also simultaneously analyze the content of biological salts.

In addition, the pull-down technology looks very sophisticated, but in fact it is as efficient as a pregnancy test stick.

The result came in less than two minutes.

Wang Qiang's voice came slowly from the loudspeaker on the podium:

"Teacher, the protein content in the target sample is not high and the biological salt content is very small. Basically, the possibility of carbon based biological eggs can be ruled out."

The result was expected by Lin Li, so he quickly continued to convey his instructions:

"Well, go to the next step and directly analyze the component content of this material."

"I see!"

Wang Qiang continued to pass the sample to Ren Yongcun for the next stage of testing.

As a big food country.

Rabbits have rich and accurate detection methods for lipids, so neon can break our wrists with us.

So it's the same as pull down.

After only half an hour, Wang Qiang and they had a new result.

Then Wang Qiang returned to the command desk with the report and handed it to Lin Li:

"Teacher, the result came out."

Lin Li took the report and looked at it for a few times. His eyebrows suddenly turned up:

"The triglyceride, free cholesterol, acetyl CoA carboxylase index of white matter are not different from that of ordinary animal fat.

But there are a lot of solidified small particles? "

Wang Qiang nodded slightly, with a dignified tone:

"The size of this particle is a little smaller than nano fat, and it's strange

Our mass spectrometer can't detect any of its components. "

Lin Li looked at her strangely and said softly:

"Why?

It's understandable that the detailed components can't be analyzed. In fact, there are many local things that still don't understand what their detailed components are.

But a solid particle can't even detect the slightest basic component? "

As Lin Li said.

The concept of unknown matter exists not only in the Da Mo world, but also in China.

For example, a typical dodecyl succinimide.

Before 2013, this thing was a standard compound that could be found but could not be fully resolved. It could only be determined that it had piperidinyl.

Another example is the umbilical cord of pregnant women alone. At present, there are no less than 40 substances with an unknown picture.

But no matter how hard it is to analyze, as long as it is a solid.

Then the existing level of science and technology can still detect some information.

For example, the chemical characteristics of anion injection.

Another example is the basic prime spectrum and so on.

So strictly speaking.

When a compound is discovered, it is not completely unknown.

It's just that the resolution is 99% or 9.9%.

In the face of questions.

Wang Qiang sighed and said in some frustration:

"Teacher, I understand what you mean.

In theory, what we can see with the naked eye means that it will reflect light.

It can reflect light, and the spectrum can be collected and analyzed technically.

But it is strange that the spectrum of such particles cannot be determined.

At the same time, we can observe these particles with the naked eye through the microscope, and obvious surface bulges can also be detected by microwave detection.

But when we use microneedles to sample, what we poke is a blank.

In addition, we have tried all kinds of ions, particles and rays, and the results

There's still no way to take it. "
