Ceramide is a bioactive lipid with significant roles in several biological processes including cell proliferation, apoptosis, and raft formation. Although fluorescent derivatives of ceramide are required to probe the behavior of ceramide in cells and cell membranes, commercial fluorescent ceramide derivatives do not reproduce the membrane behavior of native ceramide because of the introduction of bulky
神经酰胺是一种生物活性脂质,在包括细胞增殖,凋亡和筏形成在内的多个生物学过程中具有重要作用。尽管需要神经酰胺的荧光衍生物来探测神经酰胺在细胞和细胞膜中的行为,但是商业化的荧光神经酰胺衍生物由于在酰基链中引入了庞大的荧光团,因此无法再现天然神经酰胺的膜行为。最近,我们开发了鞘磷脂的新型荧光类似物,其中亲水荧光团ATTO488和ATTO594通过九甘醇接头连接到鞘磷脂的极性头,并证明了它们在双层膜中的分配和动态行为与天然鞘磷脂相似。在这份报告中,
