Fig. 7. Affinity enrichment of DSBSO crosslinked synthetic peptides from a complex environment.

Fig. 7

Average number of unique crosslinks after acquisition using a stepped HCD MS2 strategy identified in the DSBSO crosslinked enrichable library with or without spiking using linear tryptic HEK peptides as indicated. Controls were directly used for measurement; enriched samples were subjected to affinity enrichment. Error bars indicate standard deviations of average values, experimentally validated FDR is shown as callout, n = 3 independent samples acquired on different days. Source data are provided as a Source Data file.
