Pagination or Media Count:
Albumin was selected as a model protein for developing assay systems for monitoring degradation by proteolytic enzymes. Using a diode array detector, high-performance liquid chromatography was ideal for following albumin digestion by trypsin. The albumin peak gradually diminished and was replaced by several peaks corresponding to shorter peptides. In contrast, differential scanning calorimetry was of no value in following the disappearances of the protein. A thermal transition resulting from some confirmational change occurred at 52 C but did not change upon digestion of the protein.
