Abstract : In the past few years there have appeared many studies devoted to increasing the titer of viruses and infection ribonucleic acid (RNA) when titrating with various substances. In earlier studies the present authors pointed out that preliminary treatment of a tissue culture with DEAE-dextran in large concentrations increases the infection titer of parainfluenza viruses, while it has no effect on that of the rhinoviruses. This method, however, is quite laborious, and in addition requires lengthy exposure, as well as repeated careful washing of the tissue culture cells. The present study was devoted to the use of DEAE-dextran and dimethylsulfoxide (DMSO) in low concentrations in the supporting medium.
