ATCC®-derived CultiControl freeze-dried microorganism strains are high-quality, lyophilized microbial preparations used for quality control in microbiology laboratories. These strains are traceable to their original ATCC® (American Type Culture Collection) deposits, ensuring authenticity, reliability, and reproducibility. Designed for a wide range of applications, these freeze-dried strains are critical in validating laboratory methods, media, and diagnostic assays.
Key Features
- Authenticity: Derived from authenticated ATCC® strains, ensuring traceability and confidence in results.
- Lyophilized Format: Freeze-dried for long-term stability and easy storage under standard laboratory conditions.
- Ready for Reconstitution: Requires rehydration before use, simplifying transport and storage logistics.
- Wide Range of Strains: Includes bacteria, fungi, yeasts, and other microorganisms for diverse microbiological applications.
- Standardized Preparation: Produced under controlled conditions to ensure consistent performance in laboratory testing.
- Quality Assurance: Ideal for proficiency testing, assay validation, and method verification.
Applications
- Antimicrobial Susceptibility Testing (AST):
- Used to validate disk diffusion, broth dilution, and other susceptibility testing methods for antibiotics, antifungals, and other antimicrobials.
- Examples: Staphylococcus aureus ATCC® 29213, Escherichia coli ATCC® 25922.
- Media Performance Testing:
- Evaluates the performance of microbiological media, such as selective, differential, and enrichment media.
- Example: Salmonella enterica ATCC® 14028 for Hektoen Enteric Agar.
- Sterility Testing:
- Assesses the sterility of pharmaceutical products and processes.
- Example: Bacillus subtilis ATCC® 6633.
- Proficiency Testing:
- Ensures laboratory personnel and equipment perform to regulatory and accreditation standards.
- Example: Candida albicans ATCC® 90028 for fungal testing.
- Diagnostic Assay Validation:
- Verifies the accuracy of diagnostic tests, including PCR, ELISA, and serotyping methods.
- Example: Streptococcus pneumoniae ATCC® 49619 for respiratory pathogen assays.
- Environmental Monitoring:
- Serves as positive controls in cleanroom and environmental monitoring programs.
- Example: Pseudomonas fluorescens ATCC® 13525.
Reconstitution and Usage
- Rehydration: Add the specified amount of sterile water or broth to the vial to activate the freeze-dried strain.
- Cultivation: Plate or inoculate on the recommended growth medium under specified conditions (e.g., temperature, atmosphere).
- Validation: Follow standard laboratory protocols to ensure strain viability and performance.
Storage and Stability
- Storage Conditions: Store at 2–8°C in a dry, temperature-controlled environment.
- Shelf Life: Typically stable for several years when stored properly. Check individual product labels for expiration dates.
Safety and Handling
- Handle all strains using appropriate biosafety precautions and laboratory protocols.
- Dispose of used cultures and materials according to local biohazard regulations.
Benefits
- Cost-Effective: Lyophilized strains reduce the need for frequent repurchasing due to their long shelf life.
- Global Standards: Used in labs worldwide for compliance with regulatory standards, including CLSI and EUCAST.
- Versatile: Applicable across clinical, industrial, and research microbiology settings.
ATCC®-derived CultiControl freeze-dried microorganism strains are indispensable tools for ensuring the accuracy, reliability, and reproducibility of microbiological workflows in laboratories.
