title: Heterogeneity of neuraminidase genetic information in an H1N2 reassortant influenza virus [X-7 (F1)]. Brief report.
abstract: cDNA clones of the neuraminidase gene from the reassortant influenza virus X-7 (F 1) have different sequences. Some clones are more closely related to A/Tokyo/67 neuraminidase than to the A/RI/5+/57 NA gene from which the NA of X-7 (F 1) was derived.
