Purified plasmid DNA is analyzed by agarose gel electrophoresis two-ways: plasmid fingerprinting after restriction enzyme cutting (to confirm appropriate DNA banding patterns), and uncut (to confirm the absence of unwanted multimerizations). Plasmids are one of the six constitutive luciferases transcriptional units: ELuc (Plasmid 1), FLuc (Plasmid 2), RedF (Plasmid 3), NLuc (Plasmid 4), Renilla (Plasmid 5), and GrRenilla (Plasmid 6), and the multiplex luciferase reporter vector (Plasmid 7).
