Application
荧光素钠盐被用作一种溶质，用于研究微血管渗透性。它已被用作研究血液屏障穿透性的测试分子。
水溶性荧光染料由于其分子半径小，渗透性和血管灌注研究中得到应用。 以荧光素钠作为荧光示踪剂，用于研究血脑屏障(BBB)和血脊髓屏障(BSCB)在啮齿类动物模型中的通透性。 以该染料为探针底物，研究了有机阴离子转运多肽(OATP)介导的肝细胞药物转运。荧光素钠还被应用于光致退色后 原位 溶质通过荧光恢复进入骨内。
General description
荧光素是一种黄嘌呤染料，是生物学中常用的标记试剂。

Solute transport through the bone lacunar-canalicular system is believed to be essential for osteocyte survival and function but has proved difficult to measure. We report an approach that permits direct measurement of real-time solute movement in intact bones. By using
