Sample

Transthyretin

Specimen Preperation
Sample Aggregation State PARTICLE
Vitrification Instrument HOMEMADE PLUNGER
Cryogen Name ETHANE
Sample Vitrification Details 3 uL of sample were applied onto the graphene side of the grid after it was mounted on the plunger (always at the same height), and immediately blotted for 4 seconds by holding a 1 x 6 cm piece of Whatman 1 filter paper parallel to the grid, in full contact. Timing was kept with the help of a metronome. The blotting countdown was started after the blotted liquid spot on the filter paper stopped spreading and the grid was plunged in liquid ethane at the same time the blotting paper was pulled back, in a single motion.
