Whole cell tomogram of Gemmata obscuriglobus revealing the invaginated cytoplasmic membrane, which is characteristic for many members of the phylum Planctomycetes. The ribosome-rich cytoplasm is separated by the invaginated cytoplasmic membrane from the enlarged periplasmic space.

Before tilt series acquisition, cryo focused ion beam (FIB) milling with gallium ion source was performed on a FEI Dual beam Scios (Thermo Fisher Scientific, Netherlands). Autogrids with vitrified cells were mounted onto a dedicated cryo holder and transferred onto a cooled (93K) cryo stage in the dual beam microscope. The lamellae were prepared with two parallel rectangular patterns at both sides (top and bottom) of the cells, at milling angle of 10-15deg, accelerating voltage of 30 kV and ion currents between 30-300 pA. The final thickness of the lamella (milled at the lowest ion current) was about 150-300 nm.
