Correction to: Nature Immunology https://doi.org/10.1038/s41590-019-0335-z (2019), published online 11 March 2019.
In the version of this article initially published, a reference (23) was cited incorrectly and two references (below) were not included in the second sentence of the first paragraph of the second Results subsection (‘Screening for gp61 mimotopes with different functional properties’). The correct citation is as follows: “... we replaced the very stable GFP with a slow fluorescent timer (FT)27,28.” The added references are as follows (and references have been renumbered accordingly):
27. Subach, F. V. et al. Monomeric fluorescent timers that change color from blue to red report on cellular trafficking. Nat. Chem. Biol. 5, 118–126 (2009).
28. Bending, D. et al. A timer for analyzing temporally dynamic changes in transcription during differentiation in vivo. J. Cell Biol. 217, 2931–2950 (2018).
The errors have been corrected in the print, HTML and PDF versions of the article.
