2.5 kb Molecular Ruler #1708205


Number Description Options
170-8205-MSDS 2 kb Molecular Ruler DNA Size Standard English

Use our molecular ruler to accurately assign molecular weights to DNA fragments separated by gel electrophoresis. Perfect 50% GC content eliminates spurious migration due to sequence variation, ensuring that the fragments migrate exactly according to their specified size.

Add any conventional sample loading buffer prior to loading; store at 4°C.

  • Size range: 2.5–35 kb
  • 14 bands in exact 2.5 kb increments
  • Recommended loading volume: 4 µl
  • Recommended gels:
