Sacbrood virus of honeybee - expansion state I

Virion structure and genome delivery mechanism of sacbrood honeybee virus.

Preliminar grid screening was performed manually on FEI Tecnai F20 (cryo stage).

Full virions were selected together with empty particles from the same set of micrographs. Subsequent 2D classification sorted the particles of two types. Full and empty particles were further processed separately. Empty particles classified in two types - expansion state I and II.

icosahedral asymmetric unit, std point frame
