Macro-Prep 25 S Resin is a strong cation exchange resin that offers high-resolution separations at high flow rates with medium pressures. It possesses the same rigid, macroporous, and hydrophilic properties of 50 µm Macro-Prep High S support but in a 25 µm bead that offers higher resolution.
Features and Benefits
- Benchtop to pilot-scale separations, where maximum sample recovery and purity are important
- Fewer chromatographic steps required
- Removal of protein variants and other difficult contaminants that would require additional validation if present in the final formulation
