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.

Detailed product information


Specific applications

The SARS-CoV-2 External Control Kit provides a full-process control that enables researchers to assess the performance of critical workflow steps. It is also ideal for integrated solutions that combine extraction and amplification onto a single platform.



The design, format, and validation of the SARS-CoV-2 External Control Kit brings stability to a shifting environment. This ready-to-use kit requires no further dilutions, which allows for optimal workflow, increased lab efficiency, and better consistency.

The native SARS-CoV-2 Washington state strain (2019-nCoV/USAWA1/2020) provided as a positive control in this kit is whole-genome sequenced, allowing for nearly universal use across multiple platforms. Further, this clinical isolate is heat-inactivated, ensuring its safe use in a BSL-1 environment. The whole-genome sequence of this strain is available on the ATCC Genome Portal.

The human cell line WI-38 provided as a negative control in this kit allows the user to assess for SARS-CoV-2 contamination and analyze assay performance via the detection of various human housekeeping genes.
