Most molecules have a net charge within a pH range of 2 to 10. When the pH is altered, the net charge on molecules can change drastically. In this experiment, a mixture of two chemicals is absorbed onto a solid support ion-exchange column and separated during elution under conditions that influence their net charge.

Supplier: Thermo Fisher Scientific

These columns offer a unique HILIC selectivity and low ion exchange activity. Based on Core Enhanced Technology, they provide fast, high resolution separations without the elevated back pressures required by sub-2 µm particles.

Compared to IEC series columns, polyvinyl alcohol is used as a base material offering a different separation pattern.

Supplier: Resonac

QA-825, DEAE-825: Suitable for the analysis of relatively high molecular weight compounds, such as proteins, peptides, DNA, and RNA. Usable across wide pH range between 2 and 12.

Supplier: Avantor

Avantor® Partisil® was one of the first commercially available irregular silicas. A large surface area gives it a high loading capacity. Avantor® Partisil® ion-exchange materials are widely referenced and remain one of the most popular choices for analysts.

In this experiment, students purify the restriction enzyme, Eco RI. This procedure utilised an ion exchange chromatograph step for Eco RI purification. Column fractions are assayed for the enzyme using Lambda DNA and digestion products are identified by gel electrophoresis. Fractions that contain Eco RI are identified and pooled. The total and specific activities are calculated. Recommended for advanced courses.
