Selectable reporter genes

Selectable marker genes include those conferring resistance to methotrexate (dhfr, isolated from Tn7 or plasmid R67); the antibiotics kanamycin (nptII, encoding neomycin phosphotransfcrase) and hygromycin (hptIV, encoding hygromycin phosphotransferase, .isolated from E. coli);
