Figure 2From: Glycated albumin suppresses glucose-induced insulin secretion by impairing glucose metabolism in rat pancreatic β-cellsEffects of extracellular high potassium and tolbutamide on insulin secretion. Rat islets were incubated for 24 h at 37°C with 0.1 mg/mL HA (white bar) or GA (black bar), in the presence of 30 mM K+ or 100 μM Tolb. Each bar represents the mean plus SEM of 3 separate experiments, each with n = 4.Back to article page
