Rat-mouse and mouse-mouse hybridoma cell lines were used for formation of monoclonal antibodies (MAbs) in microcapsules of
different sizes. Microcapsules were made of poly L-lysine-alginate hydrogel membranes. The effects of extracapsule liquid
film, intra-capsule and transmembrane transfer limitations of nutrients/products on system’s performance were investigated.
An agitation speed of 45 rpm (4 cm/s tip speed) was found to be optimal in spinner flasks to overcome liquid film resistances
around capsules. Capsule sizes need to be reduced to smaller than 350 ε in order to eliminate intracapsule transfer limitations
with a typical initial viable cell concentration of 0.5x105 viable cells/mL capsule. Double coating of capsules to improve strength of capsules resulted in higher transmembrane transfer
resistances. 相似文献
