The 100 bp DNA ladder (marker) is ideal for determining double chain DNA sizes between 100 and 1500 base pairs. Ladder contains 11 linear, double chain fragments of different sizes. The fragment, which has 500 base pairs, has been increased to allow easy identification. All fragments were measured precisely by both chromatography and HPLC method and mixed during production. For 5 μl loading, all fragments, except 500 bp, are 40 ng and 500 bp fragments are 100 ng. It is pre-mixed with Ladder loading paint and is ready for use.
