Substrate for Hairpin ribozyme cleavage studies
This 32-nucleotide RNA oligonucleotide is a synthetic substrate designed for trans-cleavage by the tobacco ringspot virus satellite RNA hairpin ribozyme. The substrate contains the conserved GUC trinucleotide cleavage motif embedded within an internal loop A context, which docks with loop B of the ribozyme to form the catalytically active loop–loop interface. Upon ribozyme recognition, cleavage occurs at the A↓GUC site, producing a 5′-hydroxyl and a 2′,3′-cyclic phosphate terminus.
Note: This is a substrate RNA for the Tobacco ringspot virus satellite RNA Hairpin Ribozyme (Cisterna catalog: CR92). It is intended to be used in conjunction with the ribozyme for cleavage analysis.

PRIME is Cisterna's core RNA production platform, capable of synthesizing all RNA types including mRNA, tRNA, siRNA, sgRNA, aptamers, and more. The PRIME platform is engineered to drastically reduce product-related impurities such as dsRNA, short-truncated products, abortive transcripts, and DNA:RNA hybrids, all commonly generated in standard in vitro transcription. The result is consistently high-quality RNAs that are fully functional and well-suited for most downstream applications such as X-ray crystallography, Cryo-EM, tRNA aminoacylation and protein expression.
Both PRIME and SPECC reflect Cisterna’s commitment to producing high-quality RNA, but they are designed to serve different needs. PRIME is Cisterna’s standard production platform and is applicable to all RNA types. It delivers high-purity RNA suitable for a wide range of applications, from structural and biochemical studies to robust protein expression. For most research applications, PRIME offers excellent performance and exceptional value at an affordable price point. SPECC (SPEcific Capture and Cleavage) is Cisterna’s flagship purification system and is currently available for mRNA only. It takes purity a step further by selectively isolating full-length mRNA transcripts, enabling near-HPLC-level purity. SPECC is the ideal choice when the highest possible mRNA quality is desired, such as in rigorous quantitative studies, high-dose applications, or therapeutic development.
