Agarose 3:1 Agarose is a molecular biology grade, standard melting temperature agarose that yields strong gels for fine resolution of small DNA, RNA, and PCR products ≤ 1 kb. Agarose 3:1 Agarose is designed for analytical electrophoresis rather than in gel reactions or downstream applications. These easy-to-handle gels enhance the speed of gel processing and blotting. Performance testing of Agarose 3:1 Agarose ensures fine resolution of DNA fragments up to 1,000 bp, though this agarose is capable of finely resolving DNA fragments ranging from 10 bp up to 1,500 bp.
