摘要:
This invention relates generally to modified porous solid supports and processes for the preparation and use of same. In particular, passivated porous mineral oxide, polymeric, or polymer-coated mineral oxide supports are disclosed which are characterized by a reversible high sorptive capacity substantially unaccompanied by non-specific adsorption of or interaction with biomolecules. Passivation is achieved by use of a passivation mixture comprising a main monomer, a passivating monomer and a crosslinking agent, which mixture upon polymerization results in the substantial elimination of the undesirable non-specific interaction with biomolecules.
摘要:
The present invention provides small, dense mineral oxide solid supports or microbeads, comprising dense microporous mineral oxides matrices in which a skin of polymers is rooted, and their use in downstream processing, especially for fluidized bed purification of bioparticles or high molecular weight macromolecules.
