Choline-d9 is intended for use as an internal standard for the quantification of choline by GC- or LC-MS. Choline is an essential nutrient with roles in liver, neurological, hematological, and skeletal muscle homeostasis.1,2,3,4 It is a precursor in the biosynthesis of membrane phospholipids, such as phosphatidylcholine, which facilitate cell signaling and transport across the membrane, and a precursor to the neurotransmitter acetylcholine. Choline is required for hepatic lipid transport.1 Perinatal administration of choline (18.8 mg/kg) improves prenatal alcohol exposure-induced cognitive deficits in rats.2 Choline (13 mg/animal per day) improves motor coordination and behavioral deficits in a mouse model of Rett syndrome, as well as improves deficits in recognition memory induced by early-life iron deficiency in rats when administered in the drinking water at a concentration of 5 ppm.3 Deficiencies in choline intake are positively correlated with muscle wasting, and dietary administration of choline (1,000 mg/kg) increases leg and breast muscle protein content in broiler chickens.4

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。
