LACTOPHENOL BLUE, 1 x 100 mL

PRINCIPLE

Lactophenol blue is a stain used to detect yeasts and fungi. It contains phenol, lactic acid and methyl blue. There is a high concentration of phenol, which promotes the inactivation of hydrolytic enzymes, thereby preventing cell lysis. Lactic acid preserves the fungal structures and methyl blue binds to the chitin of the cell walls, leaving the fungal hyphae stained blue. Lactophenol blue is used in direct clinical samples as a mounting solution and a stain for the preparation of slides for observation under the microscope, as the blue staining of fungal structures makes it easier to view and study them.

DIAGNOSTIC USE

For the staining of fungal structures.
