Many bis-intercalating dyes used for fluorescence detection of DNA in electrophoresis have been reported to give band-splitting and band-broadening, which results in poor resolution and a decreased detection sensitivity. We have studied the dimeric dye YOYO-1, and to some extent
The binding of phenanthridine dyes to triplex poly(dT)*poly(dA).poly(dT) and its precursor duplex poly(dA).poly(dT) is characterized using linear dichroism and circular dichroism spectroscopy, and thermal denaturation. The two monomeric dyes ethidium bromide and propidium iodide are shown to behave similarly to
Fluorescence microscopy is one of the workhorses of biomedical research and laboratory diagnosis; however, their cost, size, maintenance, and fragility has prevented their adoption in developing countries or low-resource settings. Although significant advances have decreased their size, cost and accessibility
