 Gold Fiducial markers can be applied before or after the sections are placed on the grid. If they are applied before the sections, a thin film must be present for the gold to adhere to.

  • Parafilm
  • Sonicator
  • Colloidal gold solution 5 & 10nm
  • DD H2O
  • Filter paper
  • Tweezers
  • glow discharge

Procedure:

  • Put on gloves!
  • Positive stain sample grids
  • Sonicate gold solution 10-15 min
  • Glow Discharge the grid with sections
  • Place grid sample side up on parafilm
  • Deposit 1um of 10 nm gold solution
  • Allow to air dry
  • Apply sample or view grid

Do not use copper grids for immunogold labeling
