Why choose us

Safe, Reliable, and Ready To Make

An Impact

Robust

Strict quality control ensures synthetic viral controls are synthesized with precision every time, producing a robust, reliable control for your studies.

Safety

Entirely synthetic controls avoid the health and safety hazards associated with live virus controls, supporting safer workflows.

Flexible

Pick the controls that are right for you by choosing between standard, assay-ready, or encapsuled formulations.

Compares

Flexible formats for your applications

Our Synthetic Controls are offered in three formats: Standard, Assay Ready, and Encapsulated for a range of molecular and diagnostic workflows. The Standard format provides high-concentration controls in a frozen liquid, while Assay Ready Controls are dried, single-use pellets that improve stability and allow ambient shipping with freezer storage. Encapsulated Controls further enhance stability by sealing a desiccated RNA pellet in a metal capsule, enabling room-temperature shipping and storage. Together, the Assay Ready and Encapsulated formats reduce cold-chain needs, lower shipping costs, and improve global accessibility.
