Product Description
Cystine Tryptone Agar is a specialized microbiological medium designed for the selective isolation and cultivation of fastidious bacteria, particularly those requiring cysteine for growth. This high-quality agar, manufactured by Himedia, is widely used in clinical and research laboratories to support the growth of pathogens like Corynebacterium diphtheriae and other organisms that thrive in cysteine-rich environments.
The medium contains tryptone, which provides essential nitrogen and amino acids, while cystine enhances the growth of specific bacteria by supplying sulfur compounds. The balanced formulation ensures optimal recovery and isolation of target microorganisms, making it indispensable for diagnostic and research applications.
Whether you’re a student, researcher, or educator, Cystine Tryptone Agar from eqipped offers consistent performance and reliable results. The 500 gm pack size is ideal for frequent use in labs, ensuring you always have a ready supply for your experiments.
Key Applications
Cystine Tryptone Agar is commonly used for:
- Isolation and identification of Corynebacterium diphtheriae and other coryneforms.
- Differentiation of bacteria based on cysteine utilization.
- Research in microbial physiology and pathogenicity studies.
- Quality control in pharmaceutical and food microbiology labs.
Why This Medium Matters
In microbiology, the right medium can make all the difference. Cystine Tryptone Agar stands out because it supports the growth of organisms that are often difficult to culture on standard media. Its selective properties help in identifying specific pathogens, which is crucial for accurate diagnostics and research.
For students and educators, this medium is an excellent tool for teaching bacterial cultivation techniques and understanding nutritional requirements. Researchers rely on it for consistent results in studies involving fastidious bacteria.
How to Use Cystine Tryptone Agar
Preparing and using this medium is straightforward:
- Dissolve 500 gm of the powder in 1 liter of distilled water.
- Heat gently while stirring to ensure complete dissolution.
- Sterilize by autoclaving at 121°C for 15 minutes.
- Cool to 45-50°C and pour into sterile Petri dishes.
- Allow the agar to solidify before inoculating with your sample.
Always follow standard microbiological practices to avoid contamination and ensure accurate results.
Storage and Handling
Store the powder in a cool, dry place away from direct sunlight. Once prepared, the agar plates should be stored at 2-8°C and used within a reasonable timeframe to maintain efficacy.
Safety Considerations
While Cystine Tryptone Agar is generally safe, handle it with care to avoid inhalation or contact with skin and eyes. Use appropriate personal protective equipment (PPE) when preparing and handling the medium.
