524bp1180bp455bp2FRPredicted from the amplicon's own GC%+length (von Ahsen et al. 2001, at the same qPCR buffer as the primer Tm above: 50 mM Na⁺ plus 3 mM Mg²⁺ less 0.8 mM dNTP, as a sodium equivalent), not the SantaLucia model used for primer Tm, which isn't valid at this length. 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.147 bp amplicon · predicted amplicon Tm 95.0 °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.
