Map of the Chase/LV. The CAG promoter drives the expression of Chase enzymatic activity followed by the downstream expression of eGFP using the internal ribosomal entry site (IRES). CAG promoter, CMV enhancer/chicken β-actin promoter; eGFP, enhanced green fluorescent protein; LTR, long terminal repeats; RSV, Rous sarcoma virus enhancer/promoter; WPRE, woodchuck posttranscriptional regulatory element.
