Strengthen confidence in assay performance with third-party quality controls that provide an independent assessment beyond manufacturer-supplied QC. NATtrol™ whole-organism controls challenge the complete molecular workflow, from extraction through detection. Explore a broad range of infectious disease targets in both swab and liquid formats.

Puritan^® PurSafe Plus^® Collection & Transport System is 510(k) cleared for the collection, inactivation and preservation of upper respiratory tract specimens suspected of containing SARS-CoV-2. Its MK Buffer preserves RNA for up to 28 days and enables direct use without sample isolation or preparation. Available with or without HydraFlock^® flocked swabs. Now debuting in the U.S.

Most of what determines how an assay performs is decided before you run your first qPCR reaction, sequence a sample, or build an immunoassay or flow cytometry panel. The Assay Development Handbook covers the pre-analytical decisions that get locked in early and how to make them before they're permanent.
