一般說明

荧光素5(6)-异硫氰酸酯,也称为FITC,是一种弱酸性的羟基黄酮类化合物,其整体尺寸较小,在苯环上具有羧酸和异硫氰酸酯基团。这种染料具有中等大小、非平面的芳香环系。 异硫氰酸酯基团与生物分子的亲核官能团(如氨基,羟基,巯基)反应,作为荧光标记物附加在生物分子上。 该染料在相同溶剂中的最大发射波长为519纳米。

應用

荧光素5(6)-异硫氰酸(FITC)标记的分子用于非显微免疫测定和生理示踪实验。FITC在流式细胞术实验中广泛用于蛋白质、细胞核和亚核颗粒的染色。 使用FITC标记的白细胞(WBC)可用于研究其对趋化因子的反应性并进行最终测定。

Hematopoietic stem cells (HSCs) possess the ability to generate all hematopoietic cell types and to self-renew over long periods, but the mechanisms that regulate their unique properties are incompletely understood. Herein, we show that homozygous deletion of the miR-29a/b-1 bicistron

Epidemiological studies indicate that statins, cholesterol-lowering drugs, prevent aggressive prostate cancer and other types of cancer. Employing essentially non-prostate cell lines, we previously showed that statins rapidly downregulate nuclear levels of phosphorylated Akt via P2X7, a purinergic receptor recently implicated
