Image showing the SDS-PAGE separation of the purified GCR and GC proteins. (a) The molecular weight ladder is shown in the left lane. The sizes of the GCR and GC proteins were determined as 48 kDa. (b) Bioluminescence imaging of purified GCR and GC fusion proteins. Luciferase activity was positively correlated with protein concentration (0.5 and 1 μg) (). SDS-PAGE, sodium dodecylsulfate-polyacrylamide gel electrophoresis.
