In the pharmaceutical and biotechnology industries, and those that perform quality control assessments, Growth Promotion Testing (GPT) is integral in evaluating the performance and reliability of culture media used for microbial analysis. The traditional methods for preparing microorganism suspensions involve considerable time and labor, in addition, these methods have poor reproducibility.

EZ-CFU™ Single Step presents laboratories with an innovative, ready-to-use method to perform Growth Promotion Testing quickly and with improved accuracy and reproducibility. Designed to remove the tedious preparation steps, this product provides laboratories the ability to perform microbial quality control tests more readily and with greater confidence.

What is EZ-CFU™ Single Step?

EZ-CFU™ Single Step is a simple, single-use, microbiological reference preparation that contains a quantified freeze-dried preparation of an ATCC^® reference culture. Each preparation, upon the addition of water, results in a preparation containing a precise and defined concentration of microorganisms.

Its extended usability and ease of use make this product an ideal solution for pharmaceutical and biotechnology laboratories and quality control laboratories.

Key Applications

EZ-CFU™ Single Step can be used for a variety of microbiological tests, such as:

1. Growth Promotion Testing (GPT)
2. Media Challenge Testing
3. Suitability of the Counting Method
4. Suitability Tests for Specified Microorganisms
5. Microbial Limits Testing
6. Microbial Enumeration Testing
7. Microbial Neutralization Methods
8. Tests requiring low CFU numbers

Product Features and Benefits

Delivering Microbes Accurately and Reliably

1. Delivers 10–100 CFU in 0.1 mL
2. Results will be clear and reproducible

Flexibility in the Laboratory

1. Stability up to 8 hours after preparation
2. Laboratories can plan and perform tests on their own schedule

High Testing Capability

Each kit contains:

1. 20 pellets, approximately 220 tests
2. 2 vials of quantified microorganism pellets
3. 20 vials of hydrating fluid (1.2 mL each)

Reference Strains with Assured Quality

1. Microorganisms will be no more than 3 passages from the original ATCC® reference culture
2. Helps maintain the quality of the microbes

Technical Specifications

Operational advantages of EZ-CFU™ Single Step:

1. ATCC^® derivative strains
2. 3rd passage from reference culture
3. One vial containing 1.2 mL hydrating fluid with one lyophilized pellet
4. Stable at 25°C for 5 Days during Transport
5. 2°C to 8°C is the recommended storage temperature
6. Certificate of Analysis (COA) accompanies lot with ATCC® reference and mean CFU values with assay

EZ-CFU™ Single Step vs Conventional Alternatives

Some advantages EZ-CFU™ Single Step has over other systems:

1. ATCC^® derivative strains
2. 3rd passage from reference culture maintained
3. Simple preparation using 1 vial of 1.2 mL hydrating fluid and 1 lyophilized pellet
4. Remains stable at 25°C for 5 days during transportation
5. Requires storage at 2°C to 8°C
6. Accompanied by a Certificate of Analysis (COA) with ATCC^® reference and mean CFU assay values

Limitations of Conventional Alternatives

1. Frequently use NCTC® derivative strains
2. Microorganisms are usually at the 4th passage from the reference culture
3. Require the generation of a 1.1 mL suspension from one pellet
4. Demand the highly temperature-sensitive transportation of below 0°C
5. Need storage at -20°C
6. Provide a COA with NCTC^® reference and mean CFU assay values

Supporting Laboratory Efficiency and Compliance

Regulatory expectations are shifting and laboratories are looking for ways to improve the standardization, reproducibility and efficiency of their operations.

EZ-CFU™ Single Step meets these expectations by reducing the preparation time and simplifying the application of consistent microbial concentrations for routine quality control tasks.

With the implementation of ready-to-use standardized microbial preparations, laboratories are able to strengthen their operations while upholding the utmost quality of their microbiological assessments.
