Titan Krios transmission electron microscope at CEITEC equipped with phase plate and last generation direct electron detectors
Transmission electron microscope Titan Krios at Cryo-electron microscopy and tomography core facility CEITEC MU has been recently upgraded with phase plate, and two last generation direct electron detectors (FEI Falcon3EC, Gatan K2). Phase plate significantly increases contrast in cryo-electron microscopy data and allows to collect data at in-focus conditions. Moreover, increased contrast extends applicability of cryo-electron microscopy to high-resolution structural characterization of proteins and protein complexes which are around 100kDa in size. Both newly acquired direct electron detectors operate in electron counting mode, which provides superior image quality. Besides, the Gatan K2 detector position is behind the post-column energy filter and allows zero-loss imaging. Such application is primarily beneficial for imaging of thicker samples such as vitrified cells or focused ion beam micromachined cellular lamellas using cryo-electron tomography for the purpose of structural characterization of biomacromolecular complexes in situ. All upgrades were financed from the European Regional Development Fund-Project „CIISB4HEALTH“ (No. CZ.02.1.01/0.0/0.0/16_013/0001776).

Nadrian C. Seeman: DNA, not Merely the Secret of Life
We build branched DNA species that can be joined using Watson-Crick base pairing to produce N-connected objects and lattices. We have used ligation to construct DNA topological targets, such as knots, polyhedral catenanes, Borromean rings and a Solomon's knot.
