Bio-Rad manufactures a wide range of chromatography resins for process separations, providing process developers with great flexibility and high productivity. Ion exchange (IEX) is one of the most frequently used techniques for purification of proteins, peptides, nucleic acids, and other charged biomolecules. It offers high resolution with high-loading capacity. Bio‑Rad offers three different families of IEX resins — Nuvia Resins, UNOsphere Resins, and Macro‑Prep Resins.

Nuvia Resins are designed to meet specific purification challenges. These beads exhibit low nonspecific binding due to the hydrophilic nature of the polymers and deliver high resolution and high binding capacities. Nuvia IEX Resins are the ideal choice for purification of therapeutic biomolecules.
