I worked two months last year with a product made by Hanse Analytik
GmbH: bis-benzimide coupled to polyethilenglycole. The compound was to
be added to a common agarose gel in order to selectively retard DNA
fragments containing ApT sequences. A similar product, neutral red and
polyethilenglycole, was meant to "catch" CpG sequences.
I've tried high and low voltage, recirculating buffer, high and low
temperature - I never got a worthy result. Yet there are some articles
in literature with images of good gels. I only got smeared bands and
the results were never fully reproducible.
Did anybody else work with this stuff? I'd really appreciate any
