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);

The reaction occurs on an immune complex or other non cellular activating surface, then the hydrophobic binding sites cannot anchor the complex and it is released. Released C5b67 complexes can insert into the membrane of nearby cells and mediate “innocent bystander” lysis.
