AssayAssure® Product Line

Expect more from your sample preservative

Sample degradation is an unwelcome phenomenon that introduces variability to your studies. Our products provide the highest level of sample preservation that is second only to eliminating degradation itself.

The patented AssayAssure® line of products keep your samples as close as possible to how they were at the moment of collection. We do this better and for a longer period of time than any other preservative on the market.

  • Our patented preservation chemistry provides stabilization for days or weeks by maintaining cell viability, inactivating destructive chemical & biological agents, and stabilizing fragile target molecules.
  • Our products eliminate the logistics of cold-chain transport and storage.
  • The laboratory techniques surrounding our products are simple.
  • There are no proprietary sample preparation kits.
  • Our sample preservation solution permits molecular (PCR, qPCR, microarray), flow cytometry, and chemistry assays, as well as microbiology culture.
