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.146 bp amplicon · predicted amplicon Tm 82.5 °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.
