Genomic mapping
Each row is one transcript, aligned on a shared axis. A gap means that isoform skips this exonic region. Each row's box is drawn at that isoform's own real exon length, which can be narrower than the column (alternative splice site); hover a box for its exact size. A ~amber header bp means isoforms don't all agree on this region's boundary, while a plain header means they do. Navy blocks mark where the primers bind, and green (with a ✓ by the name) means this isoform has a confirmed working amplicon, not just exon overlap. A row with a “‹ exons” / “exons ›” hint instead of any box means that isoform's exons exist but sit outside the current scroll position (a truncated isoform or alternate transcription start site) — click the hint to jump to them. Click a row to load it below.
★ = Ensembl canonical transcript (reference model, not necessarily the most expressed isoform)

Off-target specificity
SpecificNo paired forward+reverse off-target amplicon found against nt (whole genome/transcriptome). Screen requires >=2 total mismatches including >=2 within the last 5bp at the 3' end to clear a hit (NCBI Primer-BLAST-style stringency); hits with >=6 total mismatches are dropped as implausible.
