ENG Scientific Acid-Fast Stain Kit (Modified for Nocardia)

Description

Includes

One 250mL bottle each of the following sollutions: Basic Fuchsin, Ethanol, Methylene Blue, Phenol, and Sulfuric Acid

The nocardiae, because of unusual long-chain fatty acids in their cell walls, can retain carbol fuchsin dye with a decolorizer of 1% sulfuric acid in water, whereas other aerobic branching bacilli cannot.

• Organisms to be stained should be emulsified in a drop of distilled water on a glass slide
• A known positive control and a known negative control should be stained along with the unknown strain
• Partially acid-fast organisms show reddish to purple filaments
• Non-acid-fast organisms stain blue
• Due to the organisms weak or partial acid-fastness, do not exceed recommended decolorizing time
• For in vitro diagnostic use only
