    Beam-induced motion correction for sub-megadalton cryo-EM particles

    Sjors HW Scheres
    Building on previous work (Bai et al., 2013), we describe an algorithm that allows cryo-EM structure determination to near-atomic resolution for protein complexes as small as 170 kDa.

    Using the Volta phase plate with defocus for cryo-EM single particle analysis

    Radostin Danev et al.
    Building on previous work in cryo-electron microscopy (Entchev et al, 2015), it shown that a combination of the Volta phase plate and a small amount of defocus can simplify the experimental set-up, increase the data acquisition rate and improve resolution.

    Cryo-EM visualization of the ribosome in termination complex with apo-RF3 and RF1

    Jesper Pallesen et al.
    Cryo-electron microscopy has been used to provide a structural interpretation of the complete action cycle of release factor 3 during translation termination, which includes a coordinated sequence of interactions with a class-I release factor and the ribosome.

    Cryo-EM single particle analysis with the Volta phase plate

    Radostin Danev, Wolfgang Baumeister
    The Volta phase plate enables in-focus single particle analysis at near atomic resolutions, which could expand the capabilities of cryo-EM, especially for small, flexible or heterogeneous macromolecular samples.
