MicroRNA (miRNA) is a kind of endogenous single stranded RNA with regulatory function found in Eukaryote, generally 18-25nt. It can cause the degradation of target mRNA and inhibit its translation through specific binding with target mRNA, so as to regulate the post transcriptional expression of genes. Recent studies have shown that miRNAs are involved in various regulatory pathways, including development, viral defense, hematopoietic processes, organ formation, cell proliferation and apoptosis, and fat metabolism. DIA-UP's advanced chemical synthesis technology can provide customers with products such as miRNA inhibitors, miRNA mimetics, miRNA negative controls, Agomir, and Antagonir.
