[Use of a 2-phase system of water-soluble polymers to concentrate measles and mumps virus].
The possibility of using two-phase systems of water-soluble polymers, polyethylene glycol (PEG) (molecular weight 6000 daltons), dextran sulphate (DS) (molecular weight 500,000 daltons), PEG- dextran (D) (molecular weight 500,000 daltons) for concentration of measles and parotitis viruses was studied. Virus concentration was found to occur in the interphase and lower phase, and the coefficient of concentration for both viruses to be 300 in the PEG-DS system and 60-100 in PEG-D system.
