Eliminating the need for refrigeration of samples will boost coronavirus testing worldwide

Hollister, CA – 16 Dec 2020. Teknova, a leading manufacturer of cell culture media and supplements, purification buffers, and molecular biology reagents, has completed the process of FDA notification for its Active Viral Transport Medium (ATM). ATM is a room temperature-stable version of Teknova’s CDC formulation Viral Transport Medium (VTM) and is manufactured under GMP conditions in compliance with ISO 13485 standards.

The requirement for refrigerated storage and transport of nasopharyngeal samples for viral testing poses significant logistical and financial challenges that have increased dramatically with mass COVID-19 testing. Teknova’s proven track record of rapid product development and expertise in media formulation make the company ideally placed to face these challenges head-on.

On the subject, Teknova CEO Stephen Gunstream said, “After the successful rollout of our VTM, we were looking for new ways in which Teknova could help in the fight against COVID-19. We realized that developing a transport medium that eliminates the need for refrigeration of samples during storage and transport would allow healthcare systems worldwide greater access to COVID-19 testing.”

After sample collection, ATM maintains viral stability at room temperature for up to 72 hours and can also be stored at room temperature prior to use. ATM is tested for pH (USP <791>), conductivity (USP <644> ) and sterility, and additional quality control is applied in the form of bioburden testing (USP <61> ). Using bovine serum albumin for ATM instead of fetal bovine serum (FBS) provides better lot-to-lot consistency and eliminates the risk of RNA degradation by RNases present in FBS, giving users and clinicians greater confidence in their test results.
