Highly derivatized agarose conformational nucleic acid separation
First Claim
1. A composition for the electrophoretic separation of conformational nucleic acid isomers comprising:
- A) an aqueous gel comprising(1) at least one agarose derivatized to the extent that it has become non-gelling or sufficiently to reduce its gelling temperature (Tg) as measured at 0.8 wt % concentration to below 9°
C., present in 40 wt % or more based upon the gel total weight, in admixture with(2) at least one high strength agarose matrix gel present in an amount which together with the derivatized agarose gives a 100 wt % total gel weight; and
B) an electrophoretic buffer, present in an electrophoretic buffer--effective amount.

Abstract
Compositions for the gel electrophoresis separation of conformational isomers of nucleic acids and agarose compositions useful in such compositions. The compositions use compositions comprising: at least one aqueous gel which is at least one highly derivatized agarose derivatized sufficiently to reduce its gelling temperature (Tg) to below 17° C., present in 40 wt % or more based upon the gel total weight, in admixture with at least one high gel-strength polysaccharide aqueous gel other than polyacrylamide in a balance to 100% total gel weight; and an electrophoretic buffer, present in an electrophoretic buffer--effective amount. The invention compositions comprise at least one aqueous gel comprising at least one agarose derivatized sufficiently to reduce its gelling temperature (Tg) to below 9° C., present in 40 wt % or more based upon the gel total weight, in admixture with at least one high strength non-acrylamide polysaccharide present in a balance to 100% total gel weight; and an electrophoretic buffer, present in an electrophoretic buffer--effective amount.
