Challenges  in Traditional Cryo-EM Sample Preparation

Cryo-EM sample preparation using traditional support grids presents

  • Air-water interface absorption
  • Badly preferred orientation
  • Sample concentration threshold (>1μM)
  • Significant background noise
  • Difficulty of reconstructing “small” macromolecules
