An internal standard for the quantification of metanephrine
Cas No.:1215507-88-2
Sample solution is provided at 25 µL, 10mM.
Metanephrine-d3 is intended for use as an internal standard for the quantification of metanephrine by GC- or LC-MS. Metanephrine is an inactive metabolite of epinephrine .1 It is formed from epinephrine by catechol-O-methyl transferase (COMT).2 Urinary and plasma levels of metanephrine are increased in patients with pheochromocytoma, an adrenal medullary neuroendocrine tumor.3,4

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。
