At present the expression system of mammalian cells such as CHO has been adopted as the conventional method to produce antibody for pharmaceuticals. However a novel method of producing antibody has been sought after as a substitute for the costly production of antibody by mammalian cells. Therefore, we tried to construct a novel antibody production system by using methylotrophic yeast, O. minuta.
We constructed a protease-deficient strain and confirmed the secretion of full-length antibody by yeast. Improving the production of antibody should be a subject of further research.
We thank N.Kawashima, A. Oonishi, Y. Yamamoto, M. Tezuka and K. Sato for their valuable assistance with this research. We are also grateful to Dr. M. Tsukahara for helpful suggestions.
