Correction to: Retrovirology 12:16 (2015) https://doi.org/10.1186/s12977-014-0134-4

Following publication of their article [1], the authors realized that honest splices in two figures were not indicated. These splices do not affect in any case the results but ought to have mentioned in the legend or indicated by white separators in the figure.

In Fig. 1c, Fractions 4–11 were run on a different gel than 1–3 because of limited slots per gel. The representation (empty lanes) does not affect the result.

c Western blot analysis of individual fractions, pooled fractions 8–10 (delineated with a broken line) and producer cell lysate

In Fig. 4c we left out the MW marker but did not indicate the splice. Again, this representation did not affect the results.

c Pull-down of His-MBP-sPol_PRD25N using recombinant Flag-LEDGF/p75WT or Flag-LEDGF/p75D366N. A MW marker was run in between input and pull-down lanes

Therefore, the authors would like to replace Figs. 1c and 4c with new ones, and update legends accordingly with the changes marked in bold.
