Figure 1 Identification of insertion of pgk + HSV-tk segment into the pMNM retroviral vector and plasmid pGEM 7Z-AFP.
Lane 1: plasmid pGEM. 7Z-AFP; Lane 2: pGEM. 7Z-AFP/Hind III 3.3 kb, 406 bp; Lane 3: pGEM. 7Z-AFP/EcoR I 3 kp, 727 bp; Lane 4: λDNA Hind III marker; Lane 5: pMNP-tk/BamH I 6.1 kb, 2.8 kb; Lane 6: pMNP-tk/EcoR I and Hind III 6.1 kb, 2.8 kb; Lane 7: pMNP-tk/EcoR I 8.9 kb; Lane 8: plasmid pMNP-tk.
Figure 2 The orientation of human AFP enhancer core sequence was defined with Hind III and BamH I digestion of the colonies of pMNAP-tk.
Lane 1-4: right junction; Lane 5: λDNA Hind III marker; lane 6-8: reverse junction.
Figure 3 Structure of pMNP-tk, pMNAP-tkα, pMNAP-tkβ retroviral vectors.
LTR: Retroviral long terminal repeat sequence; NeoR: Neomycin phosphotransferase gene (for G418 selection); pgk: Human phosphoglycerokinase promotor; tk: Herpes simplex virus thymidine kinase gene; AFPe: Human α fetoprotein “home keeping” gene enhancer.
