PROtrol Influenza B Virus (Strain: Washington/02/19) (1 mL)

Influenza B Virus (Strain: Washington/02/19) is an enveloped, negative sense, single stranded RNA virus from the Orthomyxoviridae family. The diameter of an Influenza viral particle is 80-120 nm.

Influenza B Virus was propagated in MDCK cells. The viral culture fluid was clarified via centrifugation to remove cellular debris prior to inactivation.

PROtrol™ (Protein control) is formulated with viral particles that have been modified to render them non-infectious. Each vial contains 1.0 mL of Influenza B Virus PROtrol™ frozen in No FBS DMEM media.

The pre-inactivation titer was determined from an infectious aliquot. Each lot of PROtrol™ was tested using an Influenza B Virus Nucleoprotein (NP) ELISA.

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