The GeneRuler™ Biotinylated DNA Ladder is a convenient prelabeled molecular weight marker ideal for use on southern blots.

• 21 distinct bands are visible from 100 bp-10 kb
• Bright bands at 3000 bp, 1031 bp, and 500 bp serve as reference for easy orientation

The ladder contains a mixture of labeled and unlabeled DNA which migrate uniformly and will not interfere or cross hybridize with the target.
