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 DEG 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 DEG 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. |
