Q

How to prepare a wet mound

A
  1. Obtain a clean microscope slide and a cover slip.
  2. Use the broad end of the toothpick to scrape the inside of your cheek.
  3. Place the cells on the center of the slide.
  4. Place a water drop on the cells and stir the cells with the toothpick.
  5. Allow the cells to dry for a minute or two.
  6. Place the cover slip next to the water drop at about a 60 degree angle.
  7. Slowly lower the cover slip until it rests flat on the slide.
  8. Place a drop or two of METHYLENE-BLUE stain on the slide beside the cover slip.
  9. Use a piece of paper towel to draw the stain under the cov slip by placing it opposite the stain.
