Why Is Heat Not Used In Capsule Staining at Joy Herman blog

Why Is Heat Not Used In Capsule Staining. Wash off the excess dye with 20% copper sulfate solution. Observe using oil immersion microscopy. Capsules stick well to glass, and heat may destroy the capsule. Stain with crystal violet for one minute. In addition to this, avoid steps like washing or rinsing because it can dislodge the bacterial cell capsule. Capsule staining is more difficult than other types of differential staining procedures because the capsular materials are water. Mix in a small amount of culture. A capsule can be easily destroyed by heat treatment, due to which a step of heat fixing is skipped in capsule staining. Do not use a water drop in this sample preparation. Shake off the excess copper sulfate solution and immediately blot dry. In capsule staining procedure “we do not heat fix and rinse the smear with water” as heat and water may dislodge. The capsule appears as a clear unstained zone around the bacterial cell. Capsules can be detected using a negative staining procedure in which the background (the slide) and the bacteria are stained, but the capsule is not stained. Place a few drops of congo red on a clean slide.
