SDS-PAGE analysis of GFP and GFP-TAT purity. Samples were run on a 4–12% NuPAGE Bis-Tris gel under denaturing conditions. The gel was stained with SimplyBlue Safe Stain and shows apparent homogeneity of the expressed products. The construct molecular weights compare well to the calculated theoretical molecular weights of 31,113 Da and 33,144 Da for GFP and GFP-TAT, respectively.
