Allantoic fluids containing either A2/Aichi/68 or B/Mass/66 influenza viruses were absorbed
onto columns of calcium phosphate. Approximately 98% of non-viral protein was removed …

Influenza virus suspensions containing 40 000 HA units/ml. were disrupted by addition of 1:
1000 Tween 80 and by shaking with an equal volume of tri (n-butyl) phosphate, with the …

Influenza virus may be purified and rendered free of extraneous proteins by precipitation
and aggregation with polyethylene glycol at polymer concentrations of 1 to 4%. The …

Owing to the difficulties of achieving consistently good recoveries of virus from allantoic fluid
containing influenza virus by chromatography on calcium phosphate columns the factors …

Influenza virus was quantitatively recovered from infectious allantoic fluid by precipitation
with 8 per cent (wt/vol) polyethylene glycol 6000 (PEG-6000). Virus concentrated by PEG …

MATERIALS AND METHODS Active influenza virus. The type A str of virus used was
isolated in Iowa City during the 1943 epidemic. Fresh viral suspensions were obtained by …

This paper describes methods for the disruption of particles of influenza B virus (LEE strain),
efficiently and without cleavage of covalent bonds, into subunits very much smaller than the …

Abstract The zwitterionic, Empigen BB® an alkylbetaine based on a C 12–C 14 alcohol was
shown to disrupt influenza A and B viruses in such a way as to retain the biological activity of …

Highly purified influenza virus was degraded using anionic and non-ionic detergents. Best
results were obtained using the non-ionic detergent Triton N101. Tests showed that virus …
