Small interfering RNAs (siRNAs) are important RNA fragments involved in RNA interference (RNAi), targeting specific genes and regulating their expression. We offer siRNA sequencing services based on our next-generation sequencing platform to efficiently capture and sequence siRNAs accumulated in samples, to help you analyze their role in biological regulation, as well as to monitor the delivery and biodistribution of siRNA molecules and resolve the specificity and efficacy of siRNA therapies.
siRNA is a double-stranded RNA, usually 21-24 bp, containing 2 3'-overhang perfectly base-paired nucleotides. siRNA is widely found in fungi, invertebrates, plants and mammals, which is the intermediate utilized by the cytoplasmic surveillance system, RNAi. The siRNA generated by cleaving dsRNA or small hairpin RNA (shRNA) guides RNA-induced silencing complex (RISC) to cleave mRNA molecules. In addition, siRNA has been designed as a potential therapeutic agent as a targeted drug to downregulate specific gene expression for the treatment of autoimmune diseases, malignancies and neurodegenerative disorders. CD Genomics offers high-resolution and coverage small RNA sequencing services to help you detect known and unknown siRNAs on a large scale. In addition, we offer mRNA sequencing and whole transcriptome sequencing services, combined with siRNA expression detection, enabling you to study the role of siRNA in cell signaling and regulation mechanisms, and resolve the effect of siRNA molecules in regulating gene expression in diseases.
