3,3＇-Dioctadecyloxacarbocyanine perchlorate

CAS No. : 34215-57-1

MCE 站：3,3＇-Dioctadecyloxacarbocyanine perchlorate

产品活性：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。

研究领域：Others

作用靶点：Others

In Vitro: A fluorescent dialkyl carbocyanine dye (DiOC18(3)) is used to label muscle membranes, ａnd the membranes accessible to the dye were observed by confocal laser scanning microscopy. A loss of cell membrane integrity results from contractile activity, enabling DiOC18(3) staining of internal membranes. The resulting staining pattern is striking ａnd fibers with damaged cell membranes are easily distinguished from uninjured ones. 3,3′-Dioctadecyloxacarbocyanine perchlorate is a cationic oxacarbocyanine dye. The absorption ａnd fluorescence spectra of 3,3＇-dioctadecyloxacarbocyanine, a cationic oxacarbocyanine dye have been studied in aqueous ａnd nonaqueous media containing egg phosphatidylcholine (PC) as well as in different solvents of diverse nature. The results show the evidence of complex formation of the dye in the ground ａnd in the excited states with PC. The excited state interaction of the dye with PC suggests the electron transfer from PC to dye ａnd this is supported by photovoltage generation in a photoelectrochemical cell consisting of dye ａnd PC in aqueous medium.
