Interest in these so-called artificial gel structures is primarily WebSieving agarose is chemically modifiedto give low gelling (~35°C) and melting (~65°C) temperatures. Sievingagarose gels are poured and run like conventional agarose gels, but resolvesmall DNA fragments like nondenaturing polyacrylamide gels. They finelyresolve nucelic acid fragments less than 1000 basepairs and can distinguishfragments as ...
