Supplementary Figure 11

(A) Peptide structure with expected mass/charge (m/z) for its +2 charge state and top 5 isotopic variants. Single dye conjugates have expected m/z values of 1493.73 (+1 charge state). (B) High resolution mass spectrometry of the HPLC purified peptide confirms the presence of two Atto647N dyes. ♦indicates Atto647N conjugated to cysteine.
