Charles River offers human influenza type A and B viruses, as well as Sendai virus (Cantell strain), supplied as allantoic fluid and sucrose gradient-purified. We also provide virus preparations with customer-supplied Biosafety Level 1 and 2 viruses. Viruses are grown in specific pathogen-free (SPF) embryonated eggs and final preparations can be delivered in crude (bulk fluids), concentrated, fractioned or purified forms.
Chicken serum antibodies to Influenza A/PR/8/34 and Sendai Cantell are also readily available. These are prepared in our SPF chickens raised under strict biosecurity and HEPA-filtered air under positive pressure (FAPP) rooms.
