DL-Carnitine-d9 (chloride)
(Synonyms: DL-肉碱盐酸盐-D9氘代,DL-Carnitine-d9 chloride) 目录号 : GC47243An internal standard for the quantification of carnitine
Cas No.:1219386-75-0
Sample solution is provided at 25 µL, 10mM.
DL-Carnitine-d9 is intended for use as an internal standard for the quantification of carnitine by GC- or LC-MS. DL-Carnitine is a racemic mixture of L- and D-carnitine. Unlike L-carnitine, DL-carnitine (60 and 120 µM) does not increase glucose or urea production from L-glutamine in isolated rat liver and does not compensate for carnitine deficiency in the skeletal muscle of rats receiving a carnitine-deficient diet.1,2 DL-Carnitine induces tetanic fade in stimulated isolated rat phrenic nerve diaphragm preparations when used at a concentration of 60 µM, an effect that can be blocked by choline.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。
