Sample

TubZ-Bt

Specimen Preperation
Sample Aggregation State FILAMENT
Vitrification Instrument FEI VITROBOT MARK III
Cryogen Name ETHANE
Sample Vitrification Details TubZ was preheated at 37 degrees and polymerization was initiated with saturating GTPgammaS. TubZ was then incubated for 30 seconds at room temperature before sample application, 4.5 second blotting, and plunge-freezing into liquid ethane (FEI VITROBOT MARK III).
