Stains used by each type of microscope

• What are the stains used by transmission electron microscopes

  Uranium, lead, osmium tetroxide
• Laser scanning confocal microscope stains

  Fluorescent tags, often combine with antibodies
• Why are heavy metals used as stains in e- microscopy

  The heavy metals absorb electrons increasing contrast
• Why are antibodies used with flurescent tags

  They bind to specific molecules in the cell emitting light in the certain regions you want to examine/have higher contrast
