downstream processing

This webinar presents a downstream processing workflow for recombinant human insulin production from E. coli. Learn how proinsulin and insulin can be purified.

In this webcast, see how Nuvia HP-Q Resin, an anion exchange resin, was used to purify oligonucleotides with phosphodiester backbones in a scaleable workflow.

Process development scientists, faced with an increasing number of proteins or complex biomolecules, continuously search for robust purification methods that can be rapidly scaled for manufacturing. What are the optimal purification conditions for high throughput and yield? Which resin or resin combination best purifies the desired protein? How can an efficient, yet cost-effective process be established? The answer: use a systematic screening approach. Read on to learn more.

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. Nuvia IMAC Resin provides the mechanical strength, pore structures, ligand density, and particle size distribution required for an operational run at 300 cm/hr with a DBC of 40 mg/ml at 2 bar column backpressure. Protein purification can efficiently be scaled up from milligrams in the lab to kilograms in bioprocess manufacturing. The chemical stability of Nuvia IMAC Resins ensure efficient column regeneration, reproducibility between purification runs, extended column lifetime, and product purity. Watch our video to learn how Nuvia IMAC Resins overcome the challenges associated with process purification of proteins using metal affinity chromatography.
