Measurement of AGEs in the mouse skin by ESI-LC-MS/MS. The AGE contents in the skin of mice () were measured after hydrolysis with 6 N HCl at 100°C for 24 h. The amounts of AGEs were normalized by the dry weight (a), whereas the lysine-derived AGE contents were normalized by the lysine content and arginine-derived AGEs were normalized by the arginine content (b).
