JorVet J-326AS Acid Fast Stain Indications

This stain is useful in identifying microorganisms that are strongly acid or alcohol fast in staining. Recently they have been found to be useful in selectively staining cryptosporidium oocysts and various spirochetes.

1. Pick a portion of material with an applicator stick, mix the material in a drop of saline, spread it on a glass slide (1 x 3 inch), and allow to dry.

2. Fix the dried film in methanol for 1 minute and air dry the slide, (component A).

3. Flood the slide with Kinyoun Carbol Fuchsin (component #1), and stain for 5 minutes.

4. Wash slide with 50% Ethanol (component #2), and immediately rinse slide with water.
