Custom Chimera siRNA

As a naturally occurring post-transcriptional gene regulatory mechanism, RNAi is currently a very promising therapy due to its precise multi-targeted gene silencing. Although the RNAi approach is very favorable and promising, the inherent low half-life and instability of siRNAs in biological systems do not allow direct administration of siRNAs to achieve the desired results. The preparation of siRNA-based chimeric molecules is a good strategy to improve the effect of siRNA-targeted gene silencing. Here, as an RNA expert, BOC Sciences' siRNA chimera customization service can solve your bottleneck problem in siRNA development to a certain extent.

What is Chimera siRNA?

Advantages of siRNA

RNA interference(RNAi) is a process involving sequence-specific gene silencing, which mainly involves endogenous non-coding RNA such as microRNA(miRNA), small interfering RNA(siRNA), long non-coding RNA(lncRNA), and cyclic RNA(circRNA) to target and silence messenger RNA(mRNA) in a sequence-specific manner. RNAi has the added advantage of targeting multiple genes with homology at the same time, quickly, economically, and with the potential for site-specific targeting. To be more specific, the primary role of RNAi in cells is to down-regulate the expression of target genes, which in turn down-regulates the expression of the encoded proteins, leading to the desired results. Sequence design and customized siRNA synthesis based on project requirements can circumvent the limitations of conventional therapies, thus providing new ideas for the development of next-generation therapies.

Disadvantages of siRNA

While siRNA has shown promising results in vitro, there are inherent obstacles on the road to achieving gene silencing in vivo and making gene therapy a reality. instability of RNA molecules, low transfection efficiency and half-life, lack of site-specific targeting and distribution in target tissues, and tumor heterogeneity add to the challenges of gene silencing using the RNAi process. Chimeric siRNAs are the preferred strategy to enhance the stability, specificity, or delivery efficiency of siRNA molecules for expanding and optimizing gene therapy applications.

Chemical Method for siRNA

In the case of siRNAs, chimeric molecules can be designed by combining different RNA sequences or incorporating unnatural RNA analogs. In addition, chimeric siRNAs can be designed to have their structures modified, including chemically or by affixing them to other molecules (e.g., peptides, lipids, aptamers, etc.) to improve their targeting and uptake into specific cell types or tissues.
