This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment. Together with Kilbourne F19 (BEI Resources NR-3465), this low yield HA mutant is another example of the post-1976 presence of low- (L) and high-yield (H) mutants in swine and human H1N1 influenza isolates.Each vial contains approximately 1 mL of pooled allantoic fluid from specific-pathogen free (SPF) embryonated chicken eggs infected with a low (L) yield mutant of influenza A virus, A/swine/Nevada/101/1982 (H1N1).Kilbourne Archive HomepageKilbourne/New York Medical College Archive of Influenza Virus Reassortants and MutantsKilbourne F20 information

The parental virus was isolated from a natural infection of swine in the spring of the swine flu epidemic at Fort Dix, New Jersey, in 1976. Low- (L) and high-yield (H) HA mutants were recovered from this porcine virus.Each vial contains approximately 1 mL of pooled allantoic fluid from specific-pathogen free (SPF) embryonated chicken eggs infected with a low (L) yield mutant of influenza A virus, A/swine/Wisconsin/56/1976 (H1N1).Kilbourne Archive HomepageKilbourne/New York Medical College Archive of Influenza Virus Reassortants and MutantsKilbourne F23 information

This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment. NR-3476 is a low (L) yield back-revertant of a previously isolated high (H) yield mutant of a reassortant of X-53 (CL)-2 and A/Puerto Rico/8/1934 (H1N1). X-53 (CL)-2 was derived by cloning and passage of X-53 (Kilbourne F128; BEI Resources NR-3664), which is A/New Jersey/11/1976 (HA, NA) x A/Puerto Rico/8/1934 (H1N1). The HA gene of NR-3476 is definitively derived from influenza A/New Jersey/11/1976 (H1N1), a human isolate recovered during the 1976 swine flu epidemic at Fort Dix, NJ. All other genes are from A/Puerto Rico/8/1934 (H1N1). The derivation and properties of various A/New Jersey/11/1976 (H1N1) reassortants, as well as cloned derivatives, mutants, and re-reassortants thereof, have been described in detail. The change from H to L phenotype is associated with a single amino acid change in the HA protein.Each vial contains approximately 1 mL of pooled allantoic fluid from specific pathogen free (SPF) embryonated chicken eggs infected with reassortant/mutant influenza A virus, A/New Jersey/11/1976 (HA) x A/Puerto Rico/8/1934 (NA) (H1N1), Low (L) Yield.Kilbourne Archive HomepageKilbourne/New York Medical College Archive of Influenza Virus Reassortants and MutantsKilbourne F133 information
