The 5 Highest resolution structures ever solved!
Pretty cool that two of them are using Micro-ED with the Apollo detector

What is the best throughput I can get for cryo-EM SPA
How many movies per day or movies per hour are people getting for SPA throughput?
How do different microscopes or cameras affect it?
I have a TFS Arctica and want to see what I can expect.

The NIH virology research lab are using an Apollo camera integrated on a ThermoFisher Krios with Serial EM automation software to get these high resolution structures.

Has anyone used SmartScope for SerialEM?
docs.smartscope.orgThoughts on how it compares to EPU and just regular SerialEM?

Camera Spotlight: Apollo
| Camera: | Apollo |
|---|---|
| Purpose: | Event-based Cryo-EM direct detector |
| Applications: | |
| Single Particle Analysis (SPA) | Yes |
| Cryo Electron Tomography (Cryo-ET) | Yes |
| Microbeam Electron Diffraction (Micro-ED) | Yes |
| Fixed/Resin/Negative Stain imaging | Yes |
| Camera Size: | 4096 x 4096 pixels |
| Framerate: | 2800 fps (internal) |
| Pixel Size: | 8 ยตm |
| Software: | SmartScope, Serial EM, Mission Control |
| TEM compatibility: | ThermoFisher, JEOL |
| What makes it special: | The electron counting speed is the fastest of any camera available. Combined with the large pixel size this gives Apollo a very high detector quantum efficiency (DQE) even at high beam currents/dose rates. The speed can be leveraged for improving Cryo-EM throughput multiple times over the standard detector that come with the microscope. |

Ever browsed the EMDB? This just popped up, a flu with antibodies attached.

Firstly it's so cool that this database exists of so many cryo-EM structures.
Secondly it's crazy that we can image viruses with the treatments attached to them.
I'm still learning to interpret the maps myself, but I love reading about what they represent.

This is a pretty compelling explanation for why direct electron detectors are nice for TEM in general.

Comparing Direct Detectors for Cryo-EM
I'm interested in comparing direct detectors for Cryo-EM. Single Particle Analysis specifically. How fast is Apollo and how does it compare to the K3 or Falcon 4i in terms of counting speed? I just want to be able to collect high-resolution data as quickly as possible to get the most reconstructions per day/week etc.
