    Propidium Iodide 25535-16-4 99.77%
    Propidium Iodide (PI) is a nuclear staining agent that stains DNA. Propidium Iodide is an analogue of ethidine bromide that emits red fluorescence upon embedding in double-stranded DNA. Propidium Iodide cannot pass through living cell membranes, but it can pass through damaged cell membranes to stain the nucleus. Propidium Iodide has a fluorescence wavelength of 493/617 nm and a wavelength of 536/635 nm after Mosaic with DNA. Propidium Iodide is commonly used in the detection of apoptosis (apoptosis) or necrosis (necrosis), and is often used in flow cytometry analysis.

    BODi-1 169454-13-1
    BODi-1 is a fluorescent modulator targeting dsDNA, which binds to dsDNA via a bis-intercalation mechanism (Ex=465 nm, Em=490 nm). BODi-1 exhibits a fluorescence enhancement effect upon binding to nucleic acids, but its fluorescence intensity, anisotropy and average lifetime decrease at higher dye/DNA ratios. When BODi-1 binds to DNA in liposome complexes, it also shows red-shifted emission spectra, along with reduced quantum yield and average lifetime. BODi-1 does not induce significant DNA conformational changes when the dye/DNA ratio is below 0.01. BODi-1 can be used as a fluorescent probe for the characterization of liposome complexes and FRET studies at this ratio.
