Chromatography Video

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.

Enveloped virus and VLP purification can be difficult. Learn about key factors and a cGMP-compatible, low cost, scalable process for retrovirus vector capture.

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.

This video describes the three main steps in attaching a DynaLoop Sample Loop to the NGC™ Chromatography System to enable the injection of larger sample volumes: connecting the DynaLoop Sample Loop to the NGC Chromatography System, priming the DynaLoop Sample Loop, and creating a method in ChromLab™ Software.

The NGC pH valve provides real-time, in-line monitoring of buffer pH. In this video, you’ll learn how to connect the pH valve to the NGC System, add it to the flow path, and calibrate the valve using buffers at two different pH values. Features of the pH valve include accessible calibration ports and easy bypass of the probe when the NGC System is being cleaned.
