This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.Influenza A virus, A/swine/1976/1931-mouse adapted (H1N1) was derived from a virus isolated from a pig in the USA in 1931.Sequence information is available for influenza A virus, A/swine/USA/1976-MA/1931 (H1N1) at the Influenza Research Database. Influenza A virus, A/swine/USA/1976/1931 (H1N1) was cloned by limiting dilution at the Laboratory Center for Disease Control, Health Canada, Ottawa, and passaged twice in eggs. The cloned virus was then passaged twelve times in mouse lung, twice in Madin-Darby canine kidney (MDCK) cells, and twice in eggs before deposit to BEI Resources. Note that although NR-31681 was deposited to BEI Resources as A/swine/1976/1931-mouse adapted (H1N1), nucleotide sequence obtained from the same source material by the NIAID Influenza Genome Sequencing Consortium was deposited to NCBI and IRD as A/swine/USA/1976-MA/1931 (H1N1).Each vial contains approximately 1 mL of pooled allantoic fluid from specific pathogen free (SPF) embryonated chicken eggs infected with influenza A virus, A/swine/1976/1931-mouse adapted (H1N1).
