NOW available with 3 different tracking dye options!
Each version contains the same non-hazardous fluorescent DNA dye and loading buffer

EZ-Vision Gels
Figure 1. EZ-Vision™ One, Two and Three. Left image: 1% TAE agarose gel showing the fluorescence of AMRESCO’s 1kb Ladder (K180-250μl) stained with EZVision ™ One (lane 1), EZ-Vision™ Two (lane 2) and EZ-Vision™ Three (lane3) captured with Syngene GBox-HR Gel Doc System using SP filter selection. Right image: Digital camera photograph of the same gel as left image, showing the colors and migration position of the one fast migrating tracking dye of EZ-Vision™ One (lane 1), the two tracking dyes of EZ-Vision™ Two (lane2), and the three tracking dyes of EZ-Vision™ Three (lane 3).

EZ-Vision™ Safety Testing

Mutagenicity
Figure 2. EZ-Vision™ mutagenicity was determined by Ames testing of S. typhimurium with and without metabolic activation with an S-9 activation system. Sample concentrations tested did not produce a two-fold increase in the number revertants and did not meet the criteria for a potential mutagen.

Environmental Toxicity
Figure 3. EZ-Vision™ environmental hazard testing was determined by the CCR Title 22 Fathead Minnow Hazardous Waste Screen Bioassay. Both EZ-Vision™ Two and EZ-Vision™ Three were determined non-hazardous with LC50 > 750 mg/l.

EZ-Vision Environmental Hazard Testing

Simple, Safe and Sensitive

  • Does not alter migration of DNA during electrophoresis
  • Retains fluorescent signal longer than leading competitor
  • Sensitivity similar to Ethidim Bromide at 6ng of DNA above 500 bp, and at 12ng of DNA at 50 bp.
EZ-Vision does not retard DNA migration in agarose gels
Figure 3. Relative migration of prestained samples of dsDNA in1% agarose gel with EZVision ™, Competitor 2 Green Dye, and Ethidium Bromide. The data shows that EZ-Vision™ has much less effect on DNA migration than Ethidium Bromide or Competitor 2 Green Dye. Samples stained with EZ-Vision™ are not impeded and migrate similar to dsDNA that is stained post electrophoresis.
EZ-Vision Signal Degradation
Figure 4. EZ-Vision fluorescent signal degradation in agarose gels with U.V. exposure over time. Sample DNA was stained with EZ-Vision™ or Competitor 1 Green Dye and electrophoresed on 1% agarose gels. Following electrophoresis, gels were exposed continuously to u.v. light, and the fluorescent signal quantified at 10 minute intervals using SyneGne GBox-HR Gel Doc System, presented as % of original signal. The data demonstrates that DNA stained with EZ-Vision™ retains the fluorescence approximately twice as long as Competitor I.
