产品介绍
对DNA和染色质的出色的高亲和力复染。Excellent high affinity counterstain for DNA and chromatin。Spectral properties:Excitation (nm) 491;Emission (nm) 508Application:YODi-1 is a green fluorescent carbocyanine dimeric dye. YODi-1 is a cell-impermeant nucleic acid stain that is nonfluorescent in the absence of nucleic acids but exhibits over a thousand-fold fluorescence enhancement upon binding to dsDNA.The bright fluorescence signal and low background make YODi-1 ideal for staining nucleic acids on microarrays, as well as for nuclear and chromosome counterstaining in multicolor fluorescence labeling experiments. YODi-1 can also be used for the analysis of single molecules of DNA.
