Butyl Beads 4FF is a well-established aliphatic hydrophobic interaction medium used in Hydrophobic Interaction Chromatography (HIC). as a high throughput technique for purification of biological macromolecules. The medium is uniquely designed for any stages in the purification process, from capturing to the final polishing steps.
Butyl Beads 4FF is composed of the coupling of butyl group to the highly cross-linked 4% agarose through ether linkage, optimizing the binding capacity to target proteins. The butyl group creates a true hydrophobic medium, without interfering ionic properties. The robust physical and chemical properties, high resolution and capacity of Butyl Beads 4FF fulfills the requirements for purification of biomolecules in a laboratory and process scale application.
