Documentation

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Characteristics

Comments
MicroQuant™ strains are best-in-class controls developed to support USP General Chapters. These precisely quantitated controls are provided in a single-use format that rehydrates immediately and is easy to use and convenient to store.

Handling information

Handling procedure
  1. Remove the desired number of cryopreserved reference culture vials (gray crimp) and rehydration buffer vials (green crimp) from 2-8°C storage and place into a biosafety cabinet.  One vial of rehydration buffer should be used for each vial of reference culture.
  2. Uncap each vial. Add 0.5 mL of rehydration buffer to the reference culture vial. Recap the vial and allow the pellet to dissolve for 30 seconds. Note: To ensure that an optimal titer range is maintained for 16404-HQ-PACK™ throughout the 8-hour post rehydration usability window, a 0.5 mL fill volume is used. 
  3. Vortex on the high setting for 30 seconds to ensure the suspension is well mixed. The suspension is now useable and contains 107-108 CFU per mL.
  4. If this product is used in alignment with USP <51>, add 100 µL of the above prepared suspension to 900 µL of the test sample. 
  5. Add 9.0 mL of the USP recommended diluent (not provided) to the 1.0 mL of sample prepared in step 5. Follow the procedure detailed in USP Chapter <51> for the challenge test. 

For quantitation

  1. Follow steps 1-3 listed above.
  2. Add 100 µL of the prepared suspension to 900 µL dilution buffer.
  3. Repeat the dilution 4 times to achieve a dilution factor of 1.0 x 105
  4. From the final dilution, pipette 100 µL directly on to a non-selective media plate. Use a sterile plate spreader for optimal results.
    Note: ATCC quantitation results were obtained using 100 mm Tryptic Soy Agar plates with 1.5% Tryptone, 0.5% Soytone, 0.5% Sodium Chloide, and 1.5% Agar (plates were procured from Teknova®).
  5. Incubate plates in an incubator at the appropriate temperature and time. If following a specific pharmacopeial chapter, use the incubation conditions specified. 
  6. Following incubation, read the plate for CFU counts.

For applications outside of compendial assays, please refer to the product page for ATCC 16404 for standard growth conditions.
