SARS-CoV-2 Lineage B.1.617.2; Delta Variant (USA/PHC658/2021) – CFHI
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. These products are NOT intended for use in the manufacture or processing of injectable products subject to licensure under section 351 of the Public Health Service Act or for any other product intended for administration to humans.
