Glycation of HDL3 (2 mg/mL) by treatment of carboxymethyllysine (CML) and fructose (fruc) at 37 °C in the presence of 5% CO2. (A) Comparison of fluorescence intensity (Ex = 370 nm, Em = 440 nm) from the glycated product in HDL3 (200 μg) with the treatment of either CML (final 0, 100, 200, and 400 μM) or fructose (final 0 and 400 μM) during 144 h The data are expressed as mean ± SEM from three independent measurements with duplicate samples. *, p < 0.05; **, p < 0.01; ***, p < 0.001. (B) Electrophoretic patterns (15% SDS-PAGE) of glycated HDL3 with the treatment of either CML (final 0, 100, 200, and 400 μM) or fructose (final 0 and 400 μM) at 144 h. Five micrograms of total protein in HDL3 was equally applied to each lane. Red font indicates band intensity from three independent SDS-PAGE analyses. Lane N, native HDL3; lane M, molecular weight marker (Bio-Rad, prestained low-range).
