Abstract excerpt
A Chinese Hamster Ovary (CHO) strain producing high-level human interleukin 6 (IL-6) was obtained, by introduction of the IL-6 cDNA from which the 3' AU-rich region was deleted. The IL-6 mRNA of this strain was stable. The productivity was more than 15 times higher than the previously obtained clone, which has intact IL-6 cDNA in the same expression vector. This strain produced IL-6 at a high level of 30...
