Chromatography Systems

Taking You from Discovery to Process Development

When you are purifying proteins for drug discovery and development, it’s all about time. See how the NGC Chromatography System allows you to get to your purified protein faster and with increased reproducibility.

Build your dream chromatography system

Some of the frustrations in protein purification stem from unmet chromatography needs, such as automation, productivity, throughput, and reproducibility among others. Bio-Rad's multidimensional (Multi-D) chromatography method addresses these issues and provides solutions for faster, more efficient, and more reliable protein purifications. Find out how.

What is Multi-D chromatography?

Use the following to automate your Multi-D chromatography on the NGC System:

  • Connect an autosampler via the SIM module
  • Run an easily customizable method
  • Plumb the system with a helpful guide

The NGC Fraction Collector paired with the NGC Chromatography System has the capability to produce purified biomolecules for discovery and small-scale batch production on one hardware and software platform.

Access your fractions when, how, and in the collection vessel you need. With automated collection options for analytical to preparative chromatography applications, the NGC Fraction Collector:

  • Ensures maximum flexibility within a method by collecting into 96-well plates, tubes, and bottles
  • Collects based on customized trigger options for each phase: slope, %B, pH, and detector signals
  • Enables faster downstream analysis with easy access

ChromLab Software makes purifying proteins on the NGC Chromatography System easier. It provides intuitive navigation to all key functions, has method templates to get you started quickly, and provides single-click analysis, including peak integration and overlay.

NEW ChromLab v6.0 Software:

  • Allows easy access to all pertinent information with a single touch
  • Enables module mapping to simplify system configuration setup
  • Allows streamlined method development–based functional phases
  • Utilizes intuitive functions to ensure seamless data integration and analysis
  • Allows multisystem control from a single PC
  • Permits user, group, and NGC System management
  • Enables U.S. FDA CFR Part 11 compliance with the security edition
  • Allows changes to flow rate, %B, valve positions, and fraction collection on the fly during a method run
  • Ensures runs are not interrupted by air sensor sensitivity control

Automated Method Optimization — Scouting

With the scouting feature within ChromLab Software, easily find your optimal purification conditions:

  • In hours to days versus weeks
  • By screening single parameters in an automated fashion
  • With reproducible, automated buffer creation using the buffer blending valve and prepopulated buffer recipes
  • By evaluating several parameters within a method based on design of experiment (DOE) or screening up to 384 samples with multivariable scouting

Chromatography + Stain-Free Gels

Proven method for confirming protein purity and yield

Stain-free SDS-PAGE gels provide visual confirmation of protein purity and yield in minutes instead of hours by eliminating all staining and destaining steps. With Bio-Rad's chromatography + stain-free workflow, not only can you easily set up methods and automate much of your purification scheme using the NGC Chromatography System and our resins, but once you've collected fractions, you can easily visualize which one to run on a gel via the fraction heat map within ChromLab Software.

Why spend more time than you need to? Avoid the waste and confidently assess your fractions on stain-free gels.

Use stain-free gels to quickly:

  • Assess protein purity and MW in 25 minutes
  • Identify which fractions to pool
  • Optimize chromatography runs
