Intravenous administration of poly ICLC in rabbits yields very high plasma interferon (IFN) levels; dosages from 250 to 1000 micrograms/kg body weight are very toxic. Subcutaneous administration of poly ICLC together with a high concentration of human serum albumin potentiates the inducer activity in comparison to poly ICLC in saline. Finally, a dosage of 50 micrograms of poly ICLC in 12% serum albumin is more effective as an IFN inducer than other dosages.
