Toyopearl SuperButyl-550 has the second highest hydrophobicity of the HIC ligands offered by TBL. Its pore size is the smallest of our three butyl resins. Primary applications are for the separation of smaller proteins. Depending on the feedstock's molecular size profile, it is also useful in negative or flow through chromatography. It can be used for capture and intermediate purification process steps
