Powassan Virus (Strain: LB) is an enveloped Flavivirus that contains a linear, positive-sense single-stranded RNA. Each frozen aliquot contains 1 mL of heat inactivated viral culture fluid. 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 culturebased 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.
