The first publication featuring data recorded using the Apollo detector was published in Journal of Structural Biology: X by researchers at Florida State University. The paper is titled Characterizing the resolution and throughput of the Apollo direct electron detector.
Among many interesting results, the researchers compared the performance of Apollo with other direct detectors for CryoEM reconstructions of apoferritin and adolase on a Thermo Fisher Scientific Titan Krios microscope, operated at 300 kV. In both cases, they found that Apollo was able to achieve significantly higher resolution reconstructions for a given number of particles than competing direct detectors.
