Figure 7. Thermal stability of 4-nitrophenol (solid circles and broken line) and dopamine (open circles and solid line) sulfation activities in BeWo cells.

Figure 7

The net sulfotransferase activity was expressed as a percentage of the basal (unheated) activities. The 50% inactivation temperatures (T50) were 41.5 ± 1.0 °C and at 39.1 ± 1.0 °C for 4-nitrophenol and dopamine respectively. Each point represents mean ± S.E.M of three or more determinations.
