Improved Invitrogen DNA Ladders

Superior quality DNA ladders for accurate sample analysis

Designed to be brighter, sharper, smarter

To ensure we provide you with products of the highest quality and performance available, we are improving our Invitrogen DNA, TrackIt DNA and E-Gel DNA ladders. The new DNA ladders are engineered for sharper, brighter bands and size ranges. Review the new, upgraded, and discontinued DNA ladders, along with suggested replacements, in the table below.

Our new and upgraded ladders will be available this September, enabling you to select from smarter ladder options to meet your research needs.

Upgrades include:

  • Chromatography-purified DNA fragments for brighter, sharper bands
  • Optimized size ranges for easier analysis
  • Improved loading dyes for clear tracking and analysis
