The catecholamines, epinephrine (E) and norepinephrine (NE) are important both as neurotransmitters and hormones, and measurement of E and NE in plasma is therefore of great interest in medical research. However, the low concentrations of E and NE in plasma require an analysis method that is both specific and sensitive.

高灵敏度 LC-MS/MS 分析血浆中的儿茶酚胺

儿茶酚胺、肾上腺素 (E) 和去甲肾上腺素 (NE) 作为神经递质和激素都很重要，因此血浆中 E 和 NE 的测量在医学研究中引起了极大的兴趣。然而，血浆中 E 和 NE 浓度较低，需要一种既特异又灵敏的分析方法。
