3-METHYL-2-([1-[3-(TRIMETHYLAMMONIO)PROPYL]-4(1H)-QUINOLINYLIDENE]METHYL)-1,3-BENZOTHIAZOL-3-IUM DIIODIDE Usage And Synthesis

Description

TO-TAP-1 (Thiazole Orange Monomer, also known as TO-PRO^®-1) is a green fluorescent carbocyanine monomeric dye. TO-TAP-1 is a cell-impermeant nucleic acid stain that is nonfluorescent in the absence of nucleic acids but exhibits a multiple fluorescence enhancement upon binding to dsDNA.

The bright fluorescence signal and low background make TO-TAP-1 ideal for staining nucleic acids on microarrays, as well as for nuclear and chromosome counterstaining in multicolor fluorescence labeling experiments. TO-TAP-1 is non-cytotoxic and may be used for long-term monitoring of cell viability and dead cell detection in culture.

Uses

TO-PRO 1 is a DNA binding fluorochrome, that atached to the surface of the Feraheme (FH) nanoparticle (NP), to obtain a fluorochrome-functionalized NP. TO-PRO 1 binds DNA through intercalation, and acts as a vital fluorochrome for necrotic cells[1].

Definition

ChEBI: A C1 cyanine dye having benzothiazolium-2-yl and quinolinium-4-yl substituents.
