DEF

A solution of DNA molecules of different lengths used in agarose gel electrophoresis as a reference to estimate the size of unknown DNA [fragments].

OBS

Different DNA ladders are commercially available depending on expected DNA length. The 1kbp [kilo base pairs] ladder with fragments ranging from about 0.5 kbp to 10 or 12 kbp and the 100 bp [base pairs] ladder with fragments ranging from 100 bp to just above 1000 bp are the most frequent. DNA ladders are often produced by a suitable restriction digest of a plasmid. There are special DNA ladders for supercoiled DNA and RNA.
