The purpose of this study was to demonstrate compatibility and performance of SoloHill’s Collagen-coated microcarriers in ATMI Lifesciences’ Integrityâ„¢ PadReactorâ„¢ system. The solid polystyrene core of the collagen microcarriers prevents absorption of serum or cell products into the core of the microcarrier, and the 1.03 specific gravity and 125- to 212-μm diameter allows them to be maintained in suspension with gentle low stirring speed. These solid microcarriers provide an excellent substrate for cell growth. They can…
