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.
