(1). Bhd-floxed primer pair:
Forward primer: 5’-CCA TCA GCT CCA CCA GAA CC-3’
Reverse primer: 5’-TCT GAC CCA CTG CAG CCA C-3’
PCR product size:
Homozygous BHD-flox allele: 251 bp
Wild-type allele: 391 bp
Heterozygotes: 251bp +391 bp (note: sometimes, the 391 bp does not show up, better to use wild-type primers below to confirm)

Forward primer: 5’-CCA TCA GCT CCA CCA GAA CC-3’
Reverse primer: 5’-CCG GTA CCT TAC AAG CCG A-3’
PCR product size:
Knockout allele: 152 bp
Wild type allele: 1 kb (usually does not show up, so always use wild-type primers below to confirm)
