Supplementary Fig. 4: MALDI-ToF mass spectrum of TEMPO-HOCbl.

From: In situ observation of conformational dynamics and protein ligand–substrate interactions in outer-membrane proteins with DEER/PELDOR spectroscopy

Supplementary Fig. 4

(a) MALDI-ToF mass spectrum of the major peak from the RP-HPLC of the crude product (as highlighted in Supplementary Fig. 3). The structure of TEMPO-HOCbl is shown as the inset. (b) Zoom in view of the MALDI-ToF mass spectrum. Prominent peaks in the spectra are close to the molecular mass of TEMPO-HOCbl (1543.61 g/mol).
