MicroQuant™: Innovation in Microbial QC Testing

MicroQuant™: Innovation in Microbial QC Testing
Credit: ATCC

Traditional microbial quality control workflows are slowing you down. Labs relying on frozen stocks face persistent inefficiencies—thawing delays, complex handling, and freezer-dependent logistics—that quietly erode productivity. Even single-use formats derived from frozen stocks require freezer storage and lengthy preparation, often taking up to two hours. Worse, the use of non-authenticated strains near the upper passage limit allowed by pharmacopeia guidelines introduces variability, raising concerns about genetic drift, strain reliability, and regulatory compliance. Preparing these controls can take up to two weeks and demands multiple steps, including incubations and serial dilutions—requiring both time and technical expertise. In today’s fast-paced, precision-driven environment, can QC labs afford workflows that demand expert oversight just to maintain consistency? Enter MicroQuant™—a paradigm shift in microbial QC. These fast-dissolving, precisely quantitated pellets eliminate the bottlenecks of traditional methods. Developed under an ISO 17034–accredited lab, MicroQuant™ delivers ATCC’s authenticated microbial control strains in a single-use format that rehydrates in under a minute. No thawing. No dilution prep. No freezer dependency. MicroQuant™ ensures strain fidelity from the outset by providing passage-zero reference material, removing the variability and guesswork that plague legacy workflows. Available in both high-titer and low-titer formats, MicroQuant™ supports a wide range of QC methods, including those described in pharmacopeias. Whether you're validating assays, performing routine QC, or meeting regulatory standards, MicroQuant™ empowers your lab with speed, accuracy, and confidence. It’s not just a product—it’s a redefinition of readiness in microbial quality control.
