2-Amino-3,8-dimethylimidazo-[4,5-f]-quinoxaline (MeIQx) is a food-derived carcinogen that has been found in high temperature-cooked fish and meats.1 It is activated by hydroxylation and subsequent O-acetylation via the cytochrome P450 (CYP) isoform CYP1A2 and N-acetyltransferase 2, respectively, in UV5 cells expressing the human enzymes to a metabolite that reacts with DNA to form adducts.2 MeIQx (200 and 400 ppm in the diet) induces tumor formation in rats.3

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。
