Amount of Viral Protein. Virus proteins detected by mass spectrometry were quantified

Table 2: Amount of Viral Protein. Virus proteins detected by mass spectrometry were quantified. The amount of viral protein (femto-moles of HA, NA, NP or M1) detected per nanogram of purified virus loaded is shown. The amount of hemagglutinin and neuraminidase protein is expressed as a ratio with either the NP or M1 proteins. ND: where viral protein was not detected the ratio was not determined.
