SiRNAs are small exogenous double-stranded RNA (dsRNA) (20-25 nucleotides), which triggers the RNA interference Aptamers are short single-stranded DNA or RNA, which can bind to various targets, such as proteins, peptides,

complementary to the target gene mRNA. Meanwhile, RISC has nuclease activity, which can cut and degrade the target and have additional advantages, including improved transport into the cells and lower cost [1][4][10].
Conventional drug strategy relies on the ability of small molecule drugs to target active sites of proteins to inhibit or alter gene mRNA, and inhibit the expression of target gene. Incomplete complementarity results in mRNA translation inhibition [8]. MCE owns a professional team and state-of-the-art facilities in the production and analysis of oligonucleotides. MCE can
