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.

Learn how a team developed a single-step workflow for column purification of the Influenza A H1N1 subtype using the recently developed Nuvia HP-Q Anion Exchange Resin. This protocol is scalable, efficient, and produced good yields with high purity.

We’ve combined the chromatography process with purity and yield assessment using stain-free gels to shorten and optimize your protein purification workflow. See how it’s done.

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.

This video explains how to remove bubbles and/or reduce bubble formation in your NGC System. Tips to reduce bubbles include warming up your multiwave detector for 30 to 60 min before use and flowing buffer at 0.1–0.2 ml/min in the manual mode until a stable/flat baseline is achieved before starting a method. The system may also be flushed with 100% methanol or ethanol at purge speed, with columns out of line, to remove bubbles.
