Agarose high resolution is optimised to give exceptional separation on agarose of nucleic acid fragments below 1000 base pairs, and differing by only a few base pairs. It retains the low gelling characteristics of the standard Agarose HR, and offers significantly increased gel strength at the expense of a higher melting temperature. This results in gels which are flexible and easy to handle. These properties make it the agarose of choice for analytical gel separations to check the quality and size of amplified fragments, and for use in restriction mapping involving small digestion fragments.
