Bienvenue à une présentation scientifique sur la culture cellulaire

Ketaki Patwardhan PhD, Technical Developer, Roquette, présentera le travail réalisé par Hailong Zhang, PhD, Analytical Research Manager, Applied Science, Roquette Asia Pacific (Singapore):

  • Sujet: Polysorbates versus hydroxypropyl-betacyclodextrin (HPBCD) stability comparative study and their monoclonal antibody stability benefits
    Polysorbates are intensively used in biologics formulation as stabilizer due to their propensity to inhibit aggregation at interfaces but possesses low intrinsic stability. This study is focusing on bringing to formulator attention, as an alternative, a new class of molecules hydroxypropyl-betacyclodextrin (HPBCD). When subjected to various physical and chemical stressors: heat, light and oxidative stresses, HPBCD maintains its chemical stability with >97% recovery while polysorbate showed significant degradation. For adalimumab, as a model mAb, formulated in presence of HPBCD we observed a significant decrease in both agitation and thermal stress-induced protein aggregation and sub-visible particle formation prevention compared to polysorbate.
