How do I read this diagram?

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)

A screening estimate for ranking amplicons — that relation was fitted on oligonucleotide duplexes, so applying it at amplicon length carries more error than its published ±1.9 °C, and it is not a melt-peak prediction.191 bp amplicon · predicted amplicon Tm 87.9 °C

Off-target specificity

Specific

No 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.
