Hello everyone,

Hope you can help. Invitrogen has a product they call YO-PRO-1 (monomeric cyanine nucleic acid stain / carbocyanine nucleic acid stain - green fluorescent (491/509)). Is there another source for this dye? I have tried Googling and talking to other companies, no luck. I am going nuts having to deal with Invitrogen. Thanks for your help,
