(A) Representative thermograms of DCFHP in solution with no sodium phosphate and no Alhydrogel (AH), (black trace), no sodium phosphate and AH-adsorbed (red trace), 20 mM sodium phosphate and partially AH-adsorbed (green trace), and 200 mM sodium phosphate and partially AH-adsorbed (blue trace). (B, C) Analysis of DSC data from each sample included determination of (B) thermal melting temperature (Tm) values, and (C) apparent enthalpy (ΔH′) values. DCFHP samples were formulated in a buffer containing 20 mM Tris, 150 mM NaCl, 5% Sucrose, pH 7.5 with the indicated sodium phosphate concentrations. Representative thermograms are displayed and data are average of two duplicate scans with the error bars representing the data range.
