Adsorption of interferon to homologous and heterologous cells. Brief report.

Mouse and human interferons adsorbed well both to human and mouse cells. There was no difference in the recovering of homologous and heterologous interferons from the cells. Pretreatment of the cells with heterologous interferon did not prevent adsorption of subsequently applied homologous interferon and did not interfere with the antiviral activity of homologous interferon.
