The authors would like to retract the article "The cellular source for APOBEC3G's incorporation into HIV-1"[1]. After publication of the article, the authors realized that the electrophoretic images in Figure 4D/E, showing a reproducible result of their previous publication [2] (cited as reference 6 [1]), was mistakenly taken from the same images used in [2]. In addition, Figure 2B is an unintended duplicate image of Figure 1B. This should have been avoided by the authors' careful proofreading of the manuscript. The authors apologize to the readers, reviewers, and editors of Retrovirology for publishing these erroneous data.
