Heat-inactivated SARS-CoV-2 variant B.1.1.7

VR-3326HK ^™

Download Genome Learn about the ATCC Genome Portal

VR-3326HK is a preparation of SARS-CoV-2 strain USA/CA_CDC_5574/2020 (Alpha variant) that has been inactivated by heating. The strain was isolated in December 2020 from a nasopharyngeal swab from a human in San Diego, California, and was deposited by the Centers for Disease Control and Prevention. This heat-inactivated preparation is whole-genome sequenced and can be used as a process control in the devleopment of SARS-CoV-2 molecular diagnostic tools and can also be used to make a dilution series to estimate the level of detection. Due to high demand, this product is limited to 20 per organization per 60 days.

Documentation

Product sheet

BSL 1

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.
