Heat-treatment method for producing fatty acid-bound alpha-lactalbumin that induces tumor cell death.

HAMLET (Human Alpha-lactalbumin Made LEthal to Tumor cells), which was identified in human breast milk as an alpha-lactalbumin (LA)-oleic acid complex, kills tumor cells, selectively. Although it may have potential as a therapeutic agent against various tumor cells, only low-volume methods for its production exist. In this study, heat treatment was used to produce complexes from LAs and oleic acid using a simple method.
