Figure 1. Composite Retro-X Q Vector Set map. In this generalized version of the Q Vector Map, the common elements of all the vectors are represented. Immediately downstream of the CMV immediate early promoter, the multiple cloning site (MCS) is followed by a eukaryotic IRES that ensures a second ORF (an antibiotic resistance marker or another gene in the case of pQCXIX) is cotranscribed with the gene cloned into the MCS. The expression cassette has all of the essential elements for retroviral integration and expression.

Figure 2. Self-inactivation mechanism of the Retro-X Q Vectors. Plus strand viral RNA (blue) from the expression cassette is reverse transcribed. During integration, a circular intermediate is formed that results in duplication of the deletion in the U3 region of the 3' LTR. This inactivates the CMV/MSV hybrid promoter in the 5' LTR so that transcription can only be driven from the internal promoter, PCMV IE (Figure 1).
