Summary
A sensitive radioimmunoassay showed that circulating α-interferon in the plasma of healthy individuals was low in children and reached the highest level in the young adult, then declined gradually with age. Circulating α-interferon was 0.201±0.059 ng/ml in males (n=19) and 0.184±0.076 ng/ml in females (n=14) at ages 30–39 years old. It was noted that circulating α-interferon was maintained up to a certain level even in elderly individuals.
