    Propidium Iodide 25535-16-4 99.69%
    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.

    Thiazole Orange 107091-89-4 99.56%
    Thiazole Orange is an asymmetric anthocyanin dye that can be coupled with oligonucleotides (ONs) to prepare fluorescent hybridization probes. Thiazole Orange has been widely used in biomolecular detection and staining of DNA/ RNA in gels and can be used for reticulocyte analysis. Thiazole orange generates a significant fluorescence enhancement and high quantum yield when it binds with nucleic acids, especially RNA. Thiazole orange can permeate living cell membranes. Thiazole orange can use UV light for detection, but can also be detected with blue light. The excitation and emission of Thiazole orange are λex = 510 nm (488 nm and 470 nm also show strong excitation) and λem = 527 nm, respectively.

    Thiazole orange dimer YOYO 1 143413-85-8
    Thiazole orange dimer YOYO 1 is a green fluorescent dye used for DNA staining. It belongs to the monomethine cyanine dye family and is a tetracationic homodimer of oxazole yellow (abbreviated as YO, hence the name YOYO), usually provided as a tetraiodide salt. In aqueous buffer, the free YOYO-1 dye (λmax 458 nm; λmax 564 nm) has a very low fluorescence quantum yield, but after binding to double-stranded DNA through diintercalation, the fluorescence intensity is increased by 3200 times (λmax 489 nm; λmax 509 nm).
