GPB-30(Low Density) Butyl Hydrophobic Media (Low Density), Highly Cross-Linked Polyacrylate Microspheres, Bogen (CAT#: STEM-C-3054-LGZ)

Hydrophobic chromatography utilizes the adsorption of proteins on the hydrophobic groups of the chromatography medium at high salt concentration. When the salt concentration is reduced, different proteins are eluted in order from weak to strong hydrophobicity, so as to achieve the purpose of separation and purification. With mild operating conditions and high resolution, hydrophobic chromatography is one of the most commonly used methods for the separation and purification of biological macromolecules. The GP series of hydrophobic chromatography media developed by Bogen are based on polyacrylate microspheres with high cross-linking degree and Butyl, Octyl, Phenyl, etc. as ligands (the hydrophobicity increases in turn). Isolation and purification of plasmids, etc.
