PCR restriction analysis of genome composition and stability of cold-adapted reassortant live influenza vaccines.

Abstract excerpt

Using cold-adapted master donor strains of influenza virus as a model, an approach was developed that exploits unique nucleotide differences between the donor strains and wild-type influenza viruses for rapidly and simply determining the genome composition and genetic stability of live attenuated vaccine reassortants. The approach is based on PCR amplification of approximately 150-300-nucleotide-long regions of...
