Looking for sequence-specific agarose

Dear Steve:

This may not be the ad that you saw, but I have seen an ad for an 
additive for agarose gels that helps resolve bands of similar size but 
different sequence, and got some literature.  It is called Resolver Gold 
and is sold by Ingenius (UK distributors are R&D Systems, email address 
info at rndsystems.co.uk).  The additive preferentially binds to and 
retards A+T rich sequences.  I doubt it will pick up a single base 
difference though.  The original reference is:

     Wawer C et al. 1995, Nucleic Acids Research 23(23):4928-4929

I have not tried it yet myself, if anyone out there has experience with 
it I'd be interested to hear.  No company affiliation.

- Peter
