3-十八烷基-2-[3-(3-十八烷基-2(3H)-苯并恶唑-2-亚基)-1-丙烯-1-基]苯并恶唑高氯酸盐

用途

3,3′-Dioctadecyloxacarbocyanine perchlorate 是一种细胞膜绿色荧光探针。在进入细胞膜之前荧光非常弱,仅当进入到细胞膜后才可以被激发出很强的荧光。

荧光二烷基羰花青染料(DiOC18(3))用于标记肌肉膜,并且通过共聚焦激光扫描显微镜观察染料可接近的膜。细胞膜完整性的丧失是由收缩活性引起的,使得内膜的DiOC18(3)染色成为可能。由此产生的染色模式引人注目,细胞膜受损的纤维很容易与未受损的细胞膜区分开来[1]。 3,3'-二十八烷基羰基酞菁高氯酸盐是阳离子氧杂羰花青染料。已经在含有卵磷脂酰胆碱(PC)的水性和非水性介质以及不同性质的不同溶剂中研究了3,3'-二十八烷基羰花青菁(一种阳离子氧杂羰花青染料)的吸收和荧光光谱。结果表明,在PC中,染料在地面和激发态中形成复杂的证据。染料与PC的激发态相互作用表明电子从PC转移到染料,这是由光电化学电池在光电化学电池中产生的,光电化学电池由染料和PC在水介质中组成[2]。
