Linear Flow Rate vs. Operating Pressure

The Macro-Prep 25 S support was evaluated for linear flow rate vs. operating pressure by measuring the pressure at a series of flow rates using 1M NaCl on a 1.6 cm (ID) x 12.5 cm (H) column. The pressure plotted was determined by subtracting the pressure generated by the column when empty from the pressure generated from the column when packed.

Separation on Macro-Prep 25 S
Separation of a mixture of 1 mg of native protein from 0.23 mg of the protein with oxidized surface methione residues from treatment with t-butyl hydroperoxide on a 1.6 cm (ID) x 12.5 cm (L) column packed with Macro-Prep 25 S.Buffer A: 50 mM KH2PO4, pH 5.0. Buffer B: 50mM KH2PO4, 2 M KCl, pH 5.5; gradient: 50% B to 100 % B in 20 min; flow rate: 2 ml/min.

Macro-Prep 25 S strong cation exchange support offers high-resolution separations at high flow rates with medium pressures. It possessesthe same rigid, macroporous, and hydrophilic properties of 50 μm Macro-Prep High Q and High S resin, but in a 25 μm bead that offers higher resolution. Benefits include:

  • Benchtop to pilot-scale separations, where maximum sample recovery and purity are important
  • Fewer required chromatographic steps
  • Removal of protein variants and other difficult contaminants that would require additional validation if present in the final formulation
