HPLC is extremely versatile for the isolation of peptides and proteins from a wide variety of synthetic or biological sources. The complexity of the mixture to be chromatographed will depend on the nature of the source and the degree of preliminary clean up that can be performed. In the case of synthetic peptides, RPC is generally employed both for the initial analysis and the final large-scale purification. The isolation of proteins from a biological cocktail, however, often requires a combination of techniques to produce a homogenous sample. HPLC techniques are then introduced at the later stages following initial precipitation, clarification and preliminary separations using soft gel. Purification protocols therefore need to be tailored to the specific target molecule.
This chapter deals with the different HPLC techniques that are commonly employed for the analysis and purification of peptides and proteins. A brief overview of the theory of each mode of chromatography will be presented and then discussed in terms of the parameters that control resolution and illustrated with relevant examples. The interested reader is also referred to a number of recent publications that provide a comprehensive theoretical and practical overview of this topic.
