siRNA (small interfering RNA) is a class of double-stranded RNA molecules typically 21–23 nucleotides in length. Through the RNA interference (RNAi) pathway, siRNA specifically guides the degradation of target mRNA, leading to sequence-specific gene silencing. As one of the most mature small nucleic acid therapeutic platforms, siRNA has demonstrated significant therapeutic potential across multiple disease areas and has become a key modality in nucleic acid drug development.
Leveraging established oligonucleotide chemistry platforms and robust quality control systems, BiOligo provides high-purity siRNA products from nmol to kilogram scale to support nucleic acid drug development. With flexible options for diverse chemical modifications and molecular conjugations, we offer an integrated solution to accelerate small nucleic acid therapeutic development.
