(A) 7-Deaza-2`-deoxyguanosine (deaza-dGTP) allows PCR of the human p16INK4A promoter because the specific 140 bp product (black arrow, 140) is clearly visible whether standard Taq polymerase (no hot start) or AmpliTaq Gold (hot start) is used.

(B) dGTP gives rise to unspecific byproducts (black arrow, by), which are reduced if hot start PCR is performed. The 600 bp band of the 100 bp ladder standard is indicated (white arrow, 600).
