TOYOPEARL Butyl-650
TOYOPEARL Butyl-650 is based on a 100 nm (1000 Å) pore size polymethacrylate base material bonded with C4 groups. This resin has the second highest hydrophobicity of the TOYOPEARL HIC resins. Its pore size is the largest of our three butyl resins. Primary applications are the separation of proteins, their isoforms, and aggregate removal. It is typically used in intermediate purification and polishing steps.
TOYOPEARL Butyl-650 is available in three particle sizes, 35 µm (S-grade), 65 µm (M-grade), and 100 µm (C-grade). This resin is also available in pre-packed SkillPak columns to simplify your process development and scale up.
