Overview

1,1'-Dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate is a lipophilic dye used to record membrane voltage for fluidity studies. This retrograde stain is useful in staining neurons in vitro and in vivo because the stain is relatively nontoxic to cell bodies and the dye is retained in neurons. In addition, 1,1'-Dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate is an ideal retrograde and anterograde tracer to label the processes as well as the cell bodies of cultured neurons.
A dye used to record membrane voltage.

Note
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
