1-Methylhistamine is a major metabolite produced by the methylation of histamine catalyzed by histamine N-methyltransferase (HNMT), used to assess the metabolic level of histamine in the body[1]. As the primary inactivation product of histamine in the central nervous system and peripheral tissues, 1-Methylhistamine concentration (particularly in cerebrospinal fluid and urine) can serve as a biomarker reflecting the activity of the histaminergic nervous system, and is associated with the development and progression of neurological disorders such as Alzheimer's disease and narcolepsy[2]. 1-Methylhistamine also has the potential to be a biomarker for inflammatory diseases, as changes in its levels are associated with conditions such as allergic reactions and mast cell activation syndrome[3].

计算结果:
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。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
