Western blot of P. somniferum protein probed with anti-4′OMT, anti-SalAT, anti-COR, anti-7OMT, anti-BBE, or anti-MLP 15. Crude protein extracts were prepared from capsule, stem, leaf, and root tissue of mature plants. Sites of secondary antibody binding were visualized with nitro blue tetrazolium chloride and 5-bromo-4-chloro-3-indolyl phosphate.
