WebDec 31, 1995 · Abstract: In an in-gel polymerase chain reaction (PCR), the generation of a 1750-bp yeast DNA fragment was inhibited when yeast DNA gel-stabs or gel-slices stained with ethidium bromide (EtBr) or SYBR Green I were used. Similar inhibition occurred to a varying degree in the reamplification of PCR fragments in prokaryotic systems.
