Design of positive, negative and non-structural protein (NSP) splitzicons encoding firefly luciferase. Key: CAP = m7G-cap, NSP1-4 = Non-structural proteins from the Venezuelan Equine Encephalitis Virus (VEEV), IRES = encephalomyocarditis virus internal ribosomal entry site, UTR = untranslated region, fLuciferase = firefly luciferase, black arrow = subgenomic promoter, 51nt CSE = conserved sequence element from NSP1, SG UTR = subgenomic UTR.
