| 产品介绍 |
25-羟基维生素D2(麦角骨化醇或25-羟基骨化醇)是在肝脏中发现的一种维生素D的代谢产物。它是体内循环中最常见的一种维生素D形式之一,在确定维生素D缺乏症中起着重要作用。 应用 25-羟基维生素D2可用作通过LC-MS/MS定量分析生物液体中25-羟基维生素D2含量的分析标准品。 25-Hydroxyvitamin D2(ergocalciferol or 25-hydroxycalciferol) is a metabolite of vitamin D found in the liver. It is one of the most common forms of vitamin D circulating in the body and plays an important role in determining vitamin D deficiency.25-Hydroxyvitamin D2can be used as an analytical standard for the quantitative analysis of 25-Hydroxyvitamin D2content in biological fluids via LC-MS/MS. |
