The Pacific Northwest Center for Cryo-EM (PNCC) is offering a three-day hands-on training workshop for 4-6 trainees on “Introduction to basic theory and hands-on practice in preparing cryo-EM specimens for Single Particle Analysis”. This workshop short course will be held at PNCC from September 10th through 12th, 2024 with the 12th being an optional day. Students do not require any pre-existing knowledge of cryo-EM specimen preparation. Previous experience with negative-stain sample preparation may be useful but is not required. By workshop conclusion, trainees will be able to:

  1. Successfully freeze one (or more) benchmark samples using one (or more) of the following PNCC devices: TFS Vitrobot Mk IV, Leica GP2
  2. Clip and prepare grids for loading into an Autoloader equipped system
  3. Safely manipulate frozen grids for storage and shipping
  4. Visually identify vitrification issues and propose fixes

Optionally, on day three, students may also:

  1. Practice using their own samples with feedback from PNCC trainers
  2. Practice using different grid substrates, such as Lacey Film, AuFoil, thin-carbon, and graphene-oxide.
