Inhibitory effect of the tissue antagonism of interferon on the development of 180/TG Crocker tumor: recognition of a new murine lectin]

Crude and purified murine lectin preparations are extracted from costal cartilage (TAI). They inhibit the antiviral state induced by interferon. They also agglutinate the Crocker 180/TG tumor cells. After IP inoculation in mice, the purified lectin preparation significantly decreases tumor incidence and increases the animal's life span.
