TSKgel BioAssist S PEEK Cation Exchange Column, 13 μm, ID 10 mm x Length 10 cm

TSKgel BioAssist S columns are PEEK columns packed with porous hydrophilic polymer beads which are surface modified with a strong cation exchanger. The resin's large pores are very accessible even for high molecular weight proteins. This leads to higher chromatographic efficiency and binding capacity for purification.

The application on this page shows the analysis of bromelain, a proteolytic enzyme that is used as a nutritional supplement. Bromelain is a basic glycoprotein with a MW of 33 kDa and pI of 9.55.
