Storyboard Text

  • Can somebody please explain to me what the Gram Stain process is to me?
  • I wish I could but I don't know.
  • The Gram Stain Process is a method of staining used to assign bacteria "Gram Negative" or "Gram Positive".
  • What is the "Gram Stain Process"?
  • What's the process to the "Gram Stain Process"?
  • Yes, there are 6 steps to the "Gram Stain Process".
  • The first step you have to take is to place bacteria on a slide and place it under heat, sliding it back and forth three times.
  • Next, you use a dropper to apply the primary stain (crystal violet) to the slide and allowing it to sit for a minute and then rinse it off with water.
  • Let me guess, the next step is to use a dropper and apply Gram's iodine to the slide and let it sit for a minute?
  • Okay, I think I got it. So then, I would apply the secondary stain, safranin, and let it sit for a minute and then rinse with water. Lastly, you look at the slide then find the cell shape and arrangement
  • Yes, that's right! Now, you rinse the slide with alcohol and then using water. The gram negative is purple and the gram positive is pink.
