Butyl-S Sepharose 6 Fast Flow is the least hydrophobic resin in the Sepharose Fast Flow hydrophobic interaction chromatography (HIC) range and is particularly useful during the initial stages of a purification process to remove the bulk of impurities

• Binds and elutes relatively strong hydrophobic molecules at comparatively low salt concentrations
• The least hydrophobic resin in the well proven Sepharose Fast Flow HIC range
• Purifies recombinant Hepatitis B virus surface antigen from CHO cells
• Developed and optimized in cooperation with a process-scale manufacturer of biopharmaceuticals
• The hydrophilic nature of the base matrix ensures low levels of non-specific binding.

Butyl-S Sepharose 6 Fast Flow is part of the Sepharose Fast Flow HIC platform, which has been an industrial standard for HIC chromatography during recent decades.
