Abstract
Recombinant Chinese hamster ovary (rCHO) cells were cultivated on microcarriers for the production of human immune (Gamma) interferon. The effect of basal medium, serum, and microcarrier concentration on interferon production was investigated. The specific interferon productivity in the post‐confluent stage was similar to that in the growth stage. Control of the pH results in a significant improvement in the volumetric interferon production. The volumetric production rate of interferon by these rCHO cells did not decrease after one month of cultivation on microcarriers.
