QUANTIFOIL® Active

Self-wicking grids for use exclusively with SPT Labtech chameleon

QUANTIFOIL® Active grids are unique in being the first commercially produced grids with copper nano-wire covered bars to promote thin film formation through a process of “self-wicking”, brought to you in collaboration with our sister company SPT Labtech. This removes the variability of applying an externally applied filter paper to remove excess sample during blotting. Used in single particle cryo-EM studies with the SPT Labtech chameleon which streamlines cryo-EM sample preparation workflows with high speed blot-free vitrification, automated grid handling, and the ability to screen grids based on likely ice thickness.

The grids feature:

  • 300 mesh copper grids with copper nano-wires
  • Holey carbon support film
  • Film Geometry -  ~ 1.2 µm diameter round holes with a ~ 0.8 µm edge-to-edge spacing
  • 50 pack – product code 4150-40001
