These ZORBAX GF-250 and GF-450 size exclusion (gel filtration) columns are ideal for the size separations of proteins and other biomolecules.

• High efficiency and reproducibility with short analysis time
• Hydrophilic diol bonded phase for good protein recovery
• Compatible with organic modifiers and denaturants
• Wide usable pH range (pH 3 to 8)

Some common applications includes separations of protein monomers, dimers and aggregates, desalting, protein molecular weight estimation and separations of modified proteins.
