E-Gel EX Gels

Ultra-sensitive detection of DNA

E-Gel EX gels were developed for ultimate sensitivity and demonstrate over 5-fold greater sensitivity than comparable gels containing ethidium bromide. The superior sensitivity allows you to use lower amounts of sample, saving time and money.

Our fastest, most sensitive precast agarose gels

E-Gel EX gels offer complete resolution of DNA or RNA samples typically in just 10 minutes. These gels are ideal for a quick check of the integrity of RNA samples or routine analysis of PCR products and plasmid preparations (Figure 1). E-Gel EX gels were developed for superior sensitivity over comparable gels containing ethidium bromide (Figure 2), allowing you to use less of your valuable sample.

Check the integrity of your RNA samples using E-Gel EX gels

Figure 1. Check the integrity of your RNA samples using E-Gel EX gels. RNA samples were separated on a 2% E-Gel EX gel using the preset E-Gel EX program on the E-Gel iBase Power System. Lanes M, 5, and 10: 0.1–2 kb RNA Ladder; lanes 1–4, 6–9: mouse total RNA, 200 ng per lane.

Sensitivity of DNA detection with E-Gel EX Gels

Figure 2. Sensitivity of DNA detection with E-Gel EX Gels. Two-fold serial dilutions of a 1 kb fragment, ranging from 1,000 ng to 1 ng, were separated on a 1% E-Gel EX Gel. Blue-light transillumination (with a Safe Imager Blue-Light Transilluminator) was used during documentation.

Easily excise bands of choice

Due to its innovative design, the Invitrogen E-Gel EX precast agarose gels can be opened to allow bands of choice to be easily excised after the run.


Follow these simple steps to excise your DNA band of choice:
1. Place the cassette on a bench with the wells facing up
2. Insert the sharp edge of the gel knife in the groove between the cassette halves, and lever the knife up and down
3. Open the cassette and excise the band

DNA electrophoresis has never been so simple. Your agarose gel is always ready to use, for any application and throughput. You can separate, purify and recover your nucleic acid fragments right from the gel, fast.
