SARS-CoV-2 Lineage B.1.617.2; Delta Variant (USA/PHC658/2021) CF (Heat Inactivated)

SARS-Related Coronavirus 2 Lineage B.1.617.2; Delta Variant (Isolate: USA/PHC658/2021) is an enveloped, positive-sense single-stranded RNA virus from the Coronaviridae family and the Betacoronaviridae genus. Severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), isolate hCoV-19/USA/PHC658/2021 was isolated in Memphis, Tennessee, USA in May 2021. Under the nomenclature system introduced by GISAID (Global Initiative on Sharing All Influenza Data), SARSCoV-2, isolate hCoV-19/USA/PHC658/2021 is assigned lineage B.1.617.2 using Phylogenetic Assignment of Named Global Outbreak LINeages (PANGOLIN) tool. SARS-CoV-2, lineage B.1.617.2 was first detected in India and labelled as a variant of concern (VOC). It was labelled as Delta variant by the World Health Organization (WHO).

Each frozen aliquot contains 1 mL of heat inactivated viral culture fluid. The culture fluid was clarified prior to heat inactivation by centrifugation to remove cellular debris. The pre-inactivation titer was determined from an infectious aliquot.

Viral inactivation is verified after heat inactivation by the absence of viral growth in tissue culture-based infectivity assays.

Heat inactivated viral culture fluids are sold as consumable testing materials. The suitability and performance characteristics should be determined by your laboratory for each intended usage.
