Band compressions are ambiguous band patterns on sequencing gels caused by stable intra-strand secondary structures that are not fully denatured during electrophoresis. Their occurrence can be reduced by substituting nucleotide analogues in the sequencing mixes. 7-Deaza dGTP (c⁷dGTP) can be used to resolve G-band compressions.
