Figure 1: Histochemical GUS staining of non-transgenic and transgenic soybean seeds. Soybean seeds: event 1 (ST83-16-3-10), event 2 (ST83-28-1- 15), event 3 (ST83-37-7-10), and control. Seeds were imbibed with water for 3 hours and then stained for GUS activated overnight at 37°C. Seeds were then split down the middle and pictures taken of the outside and inside of each half.
