This previously unpublished protocol aims to amplify genotype A measles virus (MeV) strains but not non-mealses viruses.Mitchell Finger and Michael Lyon developed this in-house test in 2010.The assay targets the intergenic region between the M (matrix) and F (fusion) genes, designed as a qualitative test for investigating measles vaccine virus (MVV) strains.Numbering indicates the oligonucleotide location on the sequence with MeV strain Edmonston (Moraten vaccine), complete genome, GenBank accession number AF266287.
