MicroQuant™ – Precision in every pellet, trust in every test
MicroQuant™ is ATCC's new product line of precisely quantitated microbial reference materials used to streamline microbial quality control testing in pharmaceutical manufacturing. Leveraging an innovative cryopreservation technology, MicroQuant™ products come in the form of stable, rapidly rehydrating pellets that deliver consistent quantitation and accurate, reproducible results—addressing the key challenges faced by microbial testing laboratories. This novel product suite enables simplified workflows and quick turnaround times while adhering to strict quality standards. With nearly a century of enabling scientific progress, this new ATCC offering represents the latest step in empowering innovation, collaboration, and trust through industry-leading microbial testing solutions.
Streamline microbial QC testing
- Precisely quantitated: Products are available in high-titer (107 to 108 CFU per pellet) and low-titer (100 to 1,000 CFU per pellet; 10 assays) formats to meet USP General Chapter requirements. Our precise quantitation across batches ensures lot-to-lot consistency.
- Single-use format: Our ready-to-use format enables fast assay setup and reduces the need for special handling knowledge and maintenance of expansive microbial cultures.
- Immediate rehydration at room temperature: With a processing time of a minute, you can reduce your hands-on time while improving efficiency.
- Convenient storage at 2-8°C: MicroQuant™ products are stable in refrigerator temperatures for up to 6 months, making them easy to store and ready to use anytime—no need to thaw.
- Reliable: Each product is manufactured by ATCC under ISO 17034, so you can trust that you are receiving high-quality, original source material.

View our frequently asked questions
How do I process or store MicroQuant™ products after delivery?
MicroQuant™ should be placed in 2-8°C upon receipt and can be stored at this temperature for up to six months.
My MicroQuant™ kit was mistakenly stored in the freezer. Can I still use it?
Yes, no performance impact was observed in ATCC benchmark studies following storage in a freezer.
My MicroQuant™ kit experienced a temperature excursion at room temperature, can I still use it?
MicroQuant™ vials can remain at ambient temperature for up to 2 days without any statistically significant difference as compared to items that remained in 2-8°C storage.
What steps are needed to prepare MicroQuant™ products for use?
Refer to the Instructions for Use (IFU) and the product information sheet for information on how to prepare MicroQuant™ products for use. MicroQuant™ products can be used immediately after removal from 2-8°C storage. There is no need to thaw the vials containing the rehydrating solution or pellet.
Are we able to rehydrate MicroQuant™ products then store in the refrigerator for a week or so?
The dissolved pellet should be used within 8 hours after rehydration. Refer to the product information sheet or Instructions for Use (IFU) for additional details.
One of my MicroQuant™ pellets was fractured. Can I still use it?
MicroQuant™ pellets that may be fractured during shipment are still able to be used by following the product information sheet and Instructions for Use (IFU).
What if a MicroQuant™ component vial is cracked or broken and can't be used? How do I replace it?
In the event that a vial is cracked or broken during shipment, please email technical service at [email protected].
What are some non-selective agars that can be used with MicroQuant™ strains?
Tryptic soy agar (TSA) plates can be used with MicroQuant™ strains.
How are MicroQuant™ products manufactured and authenticated?
MicroQuant™ products are manufactured with ATCC's rigorous seed-lot and quality management systems. The novel cryopreservation technique is proprietary and patent pending to ATCC and produces a discrete pellet that is stable at refrigeration temperatures. ATCC authenticates biological materials through a rigorous process that includes genotypic, phenotypic, and functional analyses. Please refer to the Certificate of Analysis for detailed test results and authentication data for each strain.
How do I access the Certificate of Analysis (CoA) for MicroQuant™ products?
The Certificate of Analysis (CoA) for the pellet is associated with the batch number on the label for the pellet vial. The assembled kit is assigned a different batch number and does not have a separate CoA. You may also scan the QR code on a pellet vial to directly access the CoA.
