A Mixed-Mode Approach — An Alternative to a Three-Step mAb Purification Process

Monoclonal antibody (mAb) purification methods often involve the use of resin-based chromatography. In this video, we compare a three-step mAb purification workflow, which uses Nuvia Ion Exchange Resins post–Protein A capture, to a two-step purification workflow, which includes a Protein A capture step followed by a mixed-mode chromatography step using Nuvia aPrime 4A Resin, a hydrophobic anion exchange resin. We present an additional two-step purification approach using Protein A resin followed by a calcium affinity cation exchange media, CHT Ceramic Hydroxyapatite XT Media. The results of both studies demonstrate that a high purity product can be attained using one fewer unit operation than traditional workflows.

The Process of Resin Screening

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.

A Scalable Immobilized Metal Affinity Chromatography Media for Process Purification

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.

Purification of Untagged Proteins Made Attainable for Any Researcher

High purity protein is a common requirement for biochemical and structural studies. A common approach is to recombinantly express an affinity-tagged version of the protein of interest. However, this is not always a viable option. Here we showcase how the NGC Chromatography System and prepacked chromatography columns can be utilized to develop purification workflows for untagged proteins.
