Nε-(1-Carboxyethyl)-L-lysine (CEL) is an advanced glycation end product (AGE) produced by the reaction of methyl glyoxal with lysine residues in proteins.1 Protein bound, but not free, CEL binds to the receptor for AGEs (RAGE).2 CEL levels are elevated in the lens of diabetic patients with cataract.3 Long-term caloric restriction decreases CEL levels in rat heart mitochondria.4 It decreases glutamate uptake and secretion of S100B in rat hippocampal slices in a RAGE-independent manner when used at a concentration of 1 mM.5

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
