VR-1986HK Heat Inactivation
How is ATCC® VR-1986HK ™ heat-inactivated?

The heat-inactivated preparation of 2019-nCoV/USA-WA1/2020 (ATCC® VR-1986HK ™) was inactivated by heating to 65°C for 30 minutes and is therefore unable to replicate. The heat-killed material is tested for virus inactivation by culturing in Vero E6 cells (ATCC® CRL-1586 ™) for two passages of 14 days each to confirm that there is no evidence of viral replication.
