Promoter: Your promoter of interest is placed here.
Kozak: Kozak consensus sequence. It is placed in front of the start codon of the ORF of interest because it is believed to facilitate translation initiation in eukaryotes.
Reporter: A visually detectable bright fluorescent protein gene (such as TurboGFP) or a chemiluminescent protein gene (such as luciferase). This allows highly sensitive detection of promoter activity in vitro.
SV40 late pA: Simian virus 40 late polyadenylation signal. It facilitates transcriptional termination of the upstream ORF.
Ampicillin: Ampicillin resistance gene. It allows the plasmid to be maintained by ampicillin selection in E. coli.
pUC ori: pUC origin of replication. Plasmids carrying this origin exist in high copy numbers in E. coli.
