Creative Biogene provides world-class MicroRNA (miRNA) sponge service and we have been perfecting MicroRNA sponge service for many years. MicroRNA sponge is a RNA molecule with multiple tandem miRNA binding sequences that can sequester miRNAs from their endogenous target mRNAs and thus serve as a decoy , and a stably expressed miRNA sponge is particularly valuable for long-term loss-of-function studies both in vitro and in vivo.

Tandem miRNA binding sequences usually imperfectly match the target miRNA and are inserted in the 3′UTR of a reporter gene. The most common miRNA sponge design involves the insertion of a tandem multiplex artificial miRNA binding sequence into the 3′UTR of a Pol II-driven reporter gene, such as green fluorescence protein (GFP) or luciferase. In addition, there is another miRNA sponge system that utilizes the Pol III promoter to drive sponge expression, in which 5' and 3' stem-loop structures are added to stabilize the RNA products to substitute the reporter gene in the Pol II promoter system. With more and more noncoding RNAs were discovered, MicroRNA sponge has indispensable role in both scientific research and practical application.

Compared with antisense oligonucleotide inhibitor and genetic knockout, MicroRNA sponge possesses the following superiority

  • Due to encoded by plasmid, MicroRNA sponge can silence target MicroRNA stablely through eukaryotic expression vector and packaged lentivirus particle.
  • MicroRNA sponge is especially suitable for the functional research of a family of MicroRNAs because of the conserved seed sequences.
  • MicroRNA sponge is particularly valuable for long-term loss-of-function study both in vitro and in vivo.
  • Even completely unrelated miRNAs binding sequences can be constructed compatibly within one vector, so MicroRNA sponge could slience multiple miRNAs simultaneously.
