经末梢染料是一类阳离子型苯乙烯基染料，主要用于是神经突触方面的研究。神经末梢染料有一个亲脂性的尾巴（两条碳链），头部端有一个高度亲水性的阳离子基团。这类神经末梢染料起源于一种叫做FMTM的染料。Biotium结合染料的波长，命名这类染料的商品名称SynaptoGreenTM 和SynaptoRedTM。其实，Biotium的SynaptoGreen C4 等同于FM1-43,SynaptoRed C2等同于FM4-64。
Biotium还开发了一系列的可固着神经末梢染料，就是我们通常说的AM染料，AM 染料同FM染料的分子结构非常接近，主要的区别是AM染料在头部加了氨基团。氨基与甲醛基反应，这样染料与膜蛋白交联。Bitoum公司的高质量的神经末梢染料的价格极具竞争力，给广大科研工作者带来了实惠。产品参考信息见下表：
