(a–c) Development using MBP. (d–f) Application to myoc-OLF. (a, d) Chemical melt with addition of GdnHCl monitoring SO fluorescence. (b, e) Serial dilution to optimize protein concentration for subsequent assays. (c, f) Dose-dependent stabilization by ligands for MBP (red, maltose; green, maltotetraose; blue, maltitol) (c) or TMAO for myoc-OLF (f) as monitored by SO fluorescence. Error bars denote standard deviation, arrows at selected concentrations.
