    7-AAD

    From: $100 Sizes: 1 mgCatalog #: 40037

    7-AAD is a fluorescent DNA intercalator, which upon binding to dsDNA can be excited by the argon-ion laser and emits at 647 nm (1-3). 7-AAD binds selectively to GC regions of DNA, which makes the dye useful for chromosome banding studies (4).

    DiSC2(5) (high purity)

    From: $58 Sizes: 50 mgCatalog #: 40041

    DiSC2(5) (3,3′-Diethylthiadicarbocyanine, iodide) binds to DNA-DNA or PNA-DNA duplexes with a large blue-shift of the absorption spectrum. Binding of the dye to PNA-DNA hybrid, in particular, blue-shifts the dye absorption spectrum by as much as 115 nm, offering a visual method to detect nucleic acid hybridization (1,2).
