I am searching for a supplier of Bisbenzimide covalently linked to
Polyethylenglycol 6000.
Bisbenzimide should preferrentially bind to AT-rich DNA-regions.
Adding this reagent to a 2% Agarose Gel should facilitate the seperation
DNA-fragments, that share the same size, but are unrelated in Sequence (eg.
differ in % AT).
R&D Systems appently had a product named Resolver Gold, but discontinued
their Molecular Biology product-line a few years ago.
