[DIYbio] Re: $400 for 200uL YOYO-1 DNA dye, is there cheaper bis-intercalator dye?

One vial would last you forever, maybe you can ask for a sample: chances are that it would be way more that what you need for your experiments
Other DNA intercalating dyes: propidium iodide, DAPI, Hoechst

I came across this, it was used to visualise single DNA molecules in nanochannels... I'm guessing it's good at this because it has two dye molecules just nanometers apart, which also have high affinity to DNA and 1000X fluorescence intensity increase upon binding.

It's crazy to me to pay so much though, Its been around since mid-90s at least...
