Heterologous systems for expression of mammalian sulfotransferases.

This paper describes the use of both mammalian and bacterial expression systems as tools to study the structural and functional relationships of proteins encoded by cDNAs to both rat and human aryl sulfotransferases. In particular, we describe the use of the mammalian COS cell system for functional expression studies, and the use of Escherichia coli for the expression and purification of a sulfotransferase fusion protein suitable as an antigen for the generation of sulfotransferase antibodies.
