Figure 1. Mass spectrometric neutral loss screen reveals multiple stable metal-Ybt complexes.

Figure 1

Liquid chromatography-constant neutral loss (LC-CNL) chromatograms reveal new chromatographic peaks corresponding to different stable metal Ybt complexes in solutions combining apo-Ybt (top) and different metal ions. The established Ybt ligands iron, copper, and gallium were used as positive controls while Ybt solutions containing chromium, cobalt and nickel revealed new peaks that differ from apo-Ybt or other known metal-Ybt complexes. Ybt solutions containing zinc and manganese did not reveal new peaks.
