Application Note: Ion Exchange with PureSpeed Tips
5 February 2015
Ion exchange chromatography separates molecules by exploiting differences in their overall charge characteristics. It is a powerful tool for separating proteins, nucleic acids, and other molecules such as peptides. The PureSpeed purification system includes a Rainin E4 XLS pipette and pipette tips containing resin capable of carrying out ion exchange chromatography. When set up with a deepwell plate containing appropriate buffers and samples, the PureSpeed system is able to carry out standalone up-and-down pipetting.
