Analysis by SDS-PAGE of AGE-modified-Tg (in the presence of glucose, without pH adjustment at 7.4). Native Tg and AGE-Tg produced after incubation of Tg with three different concentrations of D-glucose-6-phosphate (no pH adjustment at 7.4) were analyzed by SDS-PAGE, samples of 10 μg, in a 10% separating gel under denaturing, nonreducing conditions and then stained with Coomassie blue. Lane 1: molecular weight markers (94, 67, 43, and 30 KDa), lane 2: native Tg (330 KDa), lane 3: AGE-Tg produced with 0.03 M D-glucose-6-phosphate, lane 4: AGE-Tg produced with 0.05 M D-glucose-6-phosphate, and lane 5: AGE-Tg produced with 0.11 M D-glucose-6-phosphate.
