Agomir is chemically-modified double-strand miRNA mimics which can mimic mature endogenous miRNAs after transfection into cells. They can up-regulate the endogenous miRNA activity by utilizing the natural miRNA machinery. Creative Biogene's microUP? miRNA agomir is designed to mimic mature miRNAs, and chemically modified to increase their stability and activity. They are recommended for miRNA functional in vitro and in vivo studies.
