Detection and quantitation of MetMb-Xe interaction. (a) Workflow for obtaining protein stability curves of metmyoglobin from UV-Vis data; (b) representative protein stability curve from a single replicate of metmyoglobin after nitrogen purging shows no significant shift in stability (< 0.05 M $\text{GdmCl}$) and (c) representative protein stability curve from a single replicate of metmyoglobin after exposure to 1 atm xenon shows shift of 0.3 M $\text{GdmCl}$, consistent with known binding affinity of xenon to metmyoglobin.
