title: [Host proteins in purified concentrations of the influenza virus].
abstract: A comparative study of three methods for purification and concentration of influenza virus (adsorption on and elution from formalin-treated erythrocytes, sorption method, and purification on nuclear filters) demonstrated a significant decreased in ovalbumin content. By this criterion, all the three methods of preliminary purification yield the final preparation with a similar ovalbumin content. A more detailed study of the protein composition of influenza virus concentrates showed purification by elution from formalin-treated erythrocytes to remove greated amounts of protein admixtures. Electrophoregrams of virus concentrates produced by the adsorption method using macropore glass 8000 revealed a protein which passed into the virus suspension in sufficiently large amounts. This protein was identified as conalbumin.
