Downstream process purification of proteins requires a resin with optimized bead size for ideal pressure/flow properties and decent dynamic binding capacity (DBC) that provides production efficiencies and good process economics. Our newly developed metal chelate affinity resin — Nuvia™ IMAC — provides the mechanical strength, pore structures, ligand density, and particle size distribution required for an operation run at 300 cm/hr with a DBC of > 40 mg/ml at < 2 bar column backpressure. Protein purification can efficiently be scaled…
