protein 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.

Purifying proteins that are not highly expressed can be challenging. Watch this video to learn about a case study demonstrating an efficient workflow for two-step purification of a low-expressing recombinant protein using mixed-mode chromatography.

Research into human diseases has led to the development of novel monoclonal antibody drugs. These monoclonal antibody therapies have been successful because of their specificity and selectivity. However, ongoing development and successfully launching a new mAb drug require robust and reliable methods to screen for drug targets, demonstrate drug safety and efficacy, and scale up manufacturing to meet the stringent regulatory guidelines required for approval.

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.

Purification is a multistep process toward confirmation of a target protein’s purity. In this webinar you will learn how to automate your protein purification workflow by following the creation of a hypothetical monoclonal antibody (mAb). Dr. Schaefer and Dr. Winship expertly demonstrate how the NGC Chromatography System and the AEX-500 series Autosampler work together to maximize screening capability as well as rapidly achieve therapeutic development objectives.
