The tool allows you to analyze an mRNA transcript and identify potential 19- and 21-mer siRNA candidates. Paste your RNA sequence (plain text or FASTA format) or fetch using accession number into the input field and click Scan & Score siRNAs. The tool will generate all possible siRNAs, evaluate them using multiple scoring systems, and display the results in a sortable, interactive table. Use the filters to select siRNAs with optimal potency, specificity, and stability for your experiments.
