What is Cryo-Electron Microscopy (Cryo-EM)?

www.ucsf.edu/news/2015/05/1298...
There are thousands of different kinds of proteins in our bodies, from antibodies to some hormones. Some of these proteins are so tiny and complex we haven’t been able to see or study them - until now. UCSF researchers and their team developed powerful new equipment that has revolutionized cryo-electron microscopy.

Correction:
1:13 - The voltage associated with accelerating electrons is labeled as 400 volts. It should be 300 kilo volts.

Thanks for their contribution to making cryo-EM more powerful.

This video was extremely helpful, Thank you!

[@abhishekroy6691]

Now it got 2017 nobel prize in chemistry as a greater recognition

"shoots electrons at the speed of light" ... lol

[@Hadkek]

This is an awesome video! I wish more people were able to see it

[@samtyler8087]

Does this method require the sample to be homogenized for the 2D averaging to work?

2:23 What is the PDB code of this protein molecule?

[@theeargasmchannel]

thanks a lot for this vid!

[@impactsoft2928]

what is protein code in PBD website ?

[@exodus1224]

Wait a second, did he just say the electrons travel at the speed of light? I don't know if I trust this "UCSF" guy lmao

Probably the guy narrating is not a scientist but a journalist. Happens a lot and it's kind of sad seeing the lack of cooperation. But it's not a reason to be skeptical about the discovery.

Why electron mass is not involved in the calculation of the mass number of an atom?

[@RohitKushwaha]

400volts on 1:12?

[@ucsf]

Good catch. It's actually 300 kilo volts.

[@Pabloskatepk92]

"An electron gun shoots electrons at the speed of light"? Really? Special relativity prohibits anything with mass to reach the speed of light. Electrons don't even go at the speed of light in a synchrotron... UCSF, you must do better when disseminating science.

[@TS-kt3nf]

Electrons at the speed of light? LOL

[@rajatjha707]

noble prizeeee

[@arranhickman8618]

you mention cryo, but at no point do you allude to why cryo is important, nor explain its benefits to your particular evaluation!

[@mixyroo]

Actually, they did mention why it's important and its benefits...

[@jacobvandijk6525]

I don't like this kind of commercials.

[@mivalverde8627]

please, subtitles Spanish!! 😞
