DegenPrimer: Broad-Spectrum Viral Primer Design
A browser-based bioinformatics tool for designing and checking viral primers from FASTA uploads or NCBI searches, with options for whole-genome tiling.
- For
- Researchers designing broad-spectrum viral assays
- Worth noticing
- A 30% holdout-validation default is visible, alongside an option to retrieve sequences directly from NCBI.
Field notes
The interface accepts uploaded FASTA files or sequences retrieved from NCBI E-utilities, then presents controls for deduplication, conserved-region thresholds, degenerate-base limits, mismatch tolerance, and holdout validation. It also offers tiled-amplicon presets for Illumina and two Nanopore read lengths, with options for one to four primer pools. The page identifies Primer3 v2.6.1 compiled to WebAssembly; its browser-local processing and validation behavior are described by the site, not demonstrated by results in this capture.
