Production of Bionanocapsules in Immobilized Insect Cell Culture Using Porous Biomass Support Particles

摘要

L particles, composed of the L protein of the hepatitis B virus surface antigen, are candidates for a specific gene and drug delivery system. We previously constructed stably transfected insect cells for L particle production. In this study, the cells were successfully immobilized within porous biomass support particles (BSPs) in shake-flask culture. The immobilized cells showed a high specific productivity, comparable to the maximum productivities in static and shake-flask cultures of nonimmobilized cells.
