Streamline your separations with the new Praesto HT Columns Screening KIT, pre-packed with a selection of Praesto modern, high-flow Ion Exchange and Protein A agarose resins for cost-effective, high productivity mAb purification. 

The evaluation kit includes columns in 1 ml and 5 ml bed volumes, and universal 1/16" connectors ensure compatibility with all commonly-used chromatography systems e.g. FPLC.

The HT Columns are constructed of polypropylene, ensuring biocompatibility.

The screening kit includes a selection of the following Ion Exchange and Protein A modern, high-flow agarose resins:


  • Praesto AC HT – Protein A > 50 mg hlgG/ml
  • Praesto APc HT – Alkaline-stable rProtein A > 50 mg hlgG/ml
  • Praesto AP HT – Alkaline-stable rProtein A > 65 mg hlgG/ml
