Liofilchem™ Lactophenol Cotton Blue Droppers, 10mL

The Liofilchem™ Lactophenol Cotton Blue Droppers are a blue staining solution used for the microscopic examination of fungi from clinical specimens, food, and environmental samples. The droppers allow for easy preparation of fungal slides, enabling clear visualization of fungal structures under a microscope.

Key Features

1. Rapid Staining:
   • Provides a delicate blue stain for clear observation of yeast cells, mycelia, and fruiting structures.
2. Ready-to-Use:
   • Convenient dropper bottles for accurate application.
3. Validated for Clinical and Laboratory Use:
   • Tested with control strains to ensure consistent performance.
4. Versatile Applications:
   • Suitable for clinical diagnostics, environmental testing, and food microbiology.

Kit Contents

• 10 Bottles of Lactophenol Cotton Blue Droppers (10 mL each).
• 1 Instruction Sheet.

Method Principle

• Staining Mechanism:
  • The methyl blue (Cotton Blue) binds to chitin in fungal cell walls, staining fungal structures blue, while the background appears pale blue for contrast.

Applications

1. Clinical Microbiology:
   • Examination of fungi in clinical specimens, such as skin, nails, and sputum.
2. Food and Environmental Microbiology:
   • Detection and identification of fungal contaminants in food and environmental samples.
3. Research:
   • Studies on fungal morphology and identification.

Test Procedure

1. Dispense a drop of Lactophenol Cotton Blue onto a clean microscope slide.
2. Use an inoculating needle to spread fungal culture into a thin layer on the slide.
3. Place a coverslip onto the preparation, avoiding air bubbles. Let it sit for 5 minutes.
4. Observe the slide under a microscope.

Interpretation of Results

• Result:
  • Fungal structures stain blue, making identification easier.
