What is 2′-O-Me rG (dmf) CPG Co-Polymer Coated?
2′-O-Methyl rG (dmf) CPG is an advanced, chemically protected riboguanosine solid support designed for high-efficiency oligonucleotide synthesis. The 2′-O-Methyl (2′-OMe) modification on the ribose sugar significantly improves nuclease resistance and enhances binding affinity, making it essential for therapeutic RNA applications.
The “dmf” (dimethylformamidine) group acts as a robust protecting group on the guanine base, ensuring chemical stability during the rigorous phosphoramidite synthesis process. This protection minimizes side reactions and preserves the integrity of the nucleobase throughout synthesis cycles.
Applications of 2′-O-Me rG (dmf)-CPG
This solid support is crucial in modern oligonucleotide synthesis workflows, especially when constructing sequences with a 2′-O-Methyl guanosine at the 3′ end. The pre-loaded Co-Polymer Coated CPG provides a reliable foundation for chain elongation.
Key applications include:
- Therapeutic RNA Synthesis: Ideal for siRNA, antisense oligonucleotides (ASOs), and aptamers requiring 2′-O-Methyl modifications to ensure stability and efficacy in vivo.
- CRISPR-Cas9 Guide RNA Production: Supports high-purity synthesis of gRNA components where precise 3′ modifications are critical.
- Diagnostic Probes: Enables production of molecular beacons and PCR probes with enhanced resistance to enzymatic degradation for reliable diagnostic performance.
