Fungal ITS2 PNA
Fungal ITS2 PCR Blocker
Fungal ITS2 is a high-performance PNA oligonucleotide engineered to selectively inhibit the amplification of the ITS2 rRNA region. In fungal genomic studies, ITS2 often acts as an overrepresented signal that masks more valuable genetic data. By specifically binding to the conserved cgagggcacgtctgcctgg sequence, this blocker silences dominant ITS signals, allowing researchers to uncover rare nuclear genes and low-abundance targets that would otherwise remain undetected.
Main characteristics
Fungal ITS2 PNA selectively binds conserved fungal ITS2 rRNA sequences, preventing their amplification in ITS-based assays. Thanks to its stable PNA backbone, it is resistant to nuclease degradation and ensures high specificity. This reduces off-target amplification and improves the accuracy of PCR and metagenomic workflows, making it a reliable tool for complex DNA analysis. A terminal glycine is added to the PNA structure to improve flexibility and reduce steric hindrance, which can help optimize binding efficiency without affecting specificity.
Applications
- Suppresses fungal ITS2 rRNA during PCR and qPCR for clearer DNA/RNA detection
- Enables accurate fungal profiling in microbiome studies
- Supports biodiversity and ecological metagenomic research
- Suitable for environmental and clinical sample analysis
- Improves NGS results through effective rRNA depletion
