FIG. 3.
The SclA protein was expressed as a GST fusion. GST and GST-SclA samples were separated by SDS-PAGE (12% acrylamide; reducing conditions), and two identical gels were run. One gel was stained with Coomassie brilliant blue (STAIN), and the other was subjected to Western blotting using an antiserum to GST-SclA (BLOT).
