5' ITR: 5' inverted terminal repeat. In wild type virus, 5' ITR and 3' ITR are essentially identical in sequence. They reside on two ends of the viral genome pointing in opposite directions, where they serve as the origin of viral genome replication.
Promoter: The promoter that drives your gene of interest is placed here.
Kozak: Kozak consensus sequence. It is placed in front of the start codon of the ORF of interest to facilitate translation initiation in eukaryotes.
ORF: The open reading frame of your gene of interest is placed here.
Regulatory element: Allows the user to add the Woodchuck hepatitis virus posttranscriptional regulatory element (WPRE). WPRE enhances virus stability in packaging cells, leading to higher titer of packaged virus; enhances higher expression of transgenes.
BGH pA: Bovine growth hormone polyadenylation. It facilitates transcriptional termination of the upstream ORF.
3' ITR: 3' inverted terminal repeat. See description for 5’ ITR.
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.
