I'm looking into using Gel Red dye instead of EtBr. They have
different versions. I think the 0.5 mL 10000x in water stock solution
(catalog # 41003) is what I should be getting.

I'm wondering how I would use it. It says use at 1:10000 dilution so
does that mean use 0.1uL per 1mL gel volume? If I have a 50mL gel, do
I add 5uL gel red? That would give me 100 gels. Hmm....for $100. Seems
expensive.

They also have 4L of 3x in water for $200. They say dilute to 1x but
don't say what concentration to use in a gel. What do you guys do?

Thanks
