50 bp DNA Ladder no stain is ideal for determining the size of double-stranded DNA from 50 to 500 base pairs. The ladder consists of 9 fragments that range in size from 50 – 500 bp. The 300 bp fragment has an increased intensity to allow easy identification. All fragments are blunt-ended.
The ladder ist available in 2 buffers – no stain (one should add loading dye before electrophoresis) and blue – with bromphenole blue as a tracking dye. Blue buffer contains glycerol, so the ladders is ready for loading on agarose gel.
