The bioreactor is composed of cellulose-based hollow fiber bundles with a GPIIb/IIIa functionalized inner lumen. Monolayer coverage of the inner lumen surface would provide a bioreactor with limited capacity for auto-antibody removal. To further increase the ITP bioreactor capacity without increasing reactor size, we are developing a multi-layered immobilization of GPIIb/IIIa. In this approach, we make use of multiple layers of poly-lysine, anchored by PEG, to increase the available points for attachment. The optimized bioreactor is expected to provide increased capacity for auto-antibody removal and also improve operational efficiency.
