Specializing in RNA biology for years, IntegrateRNA proudly offers circRNA knockdown service using siRNA/shRNA-mediated method. Our complete service covers from siRNA design synthesis, shRNA design construction, virus packaging (optional), cell transfection, expression test of circRNA and host gene (parental protein-coding gene), to stable cell line screening. Our dedicated scientific team will work collaboratively with you to design the right tools to accelerate your research programs.
Circular RNAs (circRNAs) are highly abundant and evolutionarily conserved RNAs generated mostly from exons of protein-coding genes. It's reported that circRNA can participate in the regulation of cell growth and development, as well as the occurrence and development of diseases through a variety of mechanisms. But assay the functions of circRNAs is not straightforward as common approaches for circRNA depletion tend to also alter the levels of mRNAs generated from the hosting gene. IntegrateRNA utilizes shRNA/siRNA targeting circRNA-specific back-splice junction to specifically downregulation the circRNA in vivo with low off-target effects.
- siRNA-mediated circRNA knockdown
siRNAs have to be complement to the back-splice site in order to be circRNA specific without affecting the host gene expression (Figure1). Thus, siRNA-mediated knockdown is limited to the backsplice junction, and negative effects on the parental protein-coding gene expression should always be tested for and ruled out.
