Overview

Purification on Macro-Prep 25Q column

Separation of 360 µl of 6xHis-tagged dihydrofolate reductase E. coli lysate on a 2 ml column packed with macro-Prep 25 Q. Buffer A: 59 mM Trist, pH 8.3. Buffer B: 50 mM Trist, pH 8.3, 1 M NaCl; gradient: 0–100% B in 10 column volumes; flow rate: 2 ml/min.

Macro-Prep 25 Q Resin is a strong anion 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 Q support but in a 25 µm bead that offers higher resolution.

Features and Benefits of Macro-Prep 25 Q Strong Anion Exchange Resin

  • 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
