Figure 5.
All-against-all orthogonality of 16 pairs of heterodimers assessed by online ion exchange chromatography coupled with native mass spectrometry. Red boxes indicate designed cognate pairs. Exchange of unlabeled and partially 15N-labeled DHD37_ABXB results in a distribution of overlapping species. Figure adapted with permission from Reference 23; copyright 2018 Springer Nature Limited.
