Abstract
In this chapter we discuss the potential of preparative SDS-PAGE for use in purifying native developing enamel matrix proteins. We believe that the methodology has the potential to provide the relatively large-scale single-step purification of any enamel protein that can be resolved as a single band during analytical SDS-PAGE. Of course, a single band on analytical SDS-PAGE does not guarantee absolute purity as the band may be comprised of two or more proteins migrating at the same apparent molecular weight on the gel. Where absolute purity is required, the methodology can be used in conjunction with other techniques such as ion-exchange chromatography or reverse-phase chromatography. We do not see preparative SDS-PAGE replacing chromatographic methodologies but believe that it can provide another powerful tool to add to the battery of purification techniques already available to researchers in the field.
