It… (More)
The matrix (M) protein of the H2N2 virus A/Ann Arbor/6/60 may be distinguished from M protein of several H3N2 viruses and A/New Jersey/76 (HSWINI) by SDS acrylamide gel electrophoresis using a discontinuous buffer system. The smallest RNA (RNA 8) of the A/Ann Arbor/6/60 virus may be distinguished from RNA 8 of several H3N2 viruses by acrylamide gel… (More)
The 75K glycoprotein of the A2 strain of respiratory syncytial virus was cleaved by digestion with trypsin or Staphylococcus aureus protease V8. The fragments resulting from trypsin digestion were 40K and 29K; those from the Staphylococcal protease were 49K and 37K.
Influenza A/Scotland/74 (H3N2) and A/Victoria/75 (H3N2) cold-adapted (ca) recombinant viruses, prepared by mating the A/Ann Arbor/6/60 (H2N2) ca donor virus and influenza A wild-type virus, were evaluated in adult seronegative volunteers (serum hemagglutination-inhibiting antibody titer, </=1:8) for level of attenuation, antigenicity, and genetic stability… (More)
