E-Gel® EX gels are the fastest resolving gels in the E-Gel® product line and feature:
• Complete separation in just 10 minutes or less
• Ultra sensitive detection of DNA
• Quick check of RNA samples
• Live monitoring of DNA migration without the hazards of UV light
• Easy access to the gel for extraction of DNA bands or transfer to membranes for Southern blotting

DNA Separation and sensitivity
Get complete separation of DNA samples in just 10 minutes or less with E-Gel® EX 1% and 2% gels. Separation time for 4% E-Gel® EX gels is 15 minutes. 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.

Quick check of RNA samples
E-Gel® EX gels can also be used for fast analysis of RNA samples to check on their integrity before proceeding with downstream applications.

Live monitoring of DNA migration
A proprietary stain incorporated in the gels is excitable by visible blue light, allowing safe, real-time monitoring of DNA or RNA migration with the E-Gel® Safe Imager Real-Time Transilluminator.

Easy access to the gel
The gel cassette is designed to allow easy opening with Invitrogen’s Gel Knife. This enables the gel inside to be accessed readily for excision of specific bands or transferred to a membrane for Southern blot analysis.

Nucleic acid markers
The E-Gel® 25bp and 50bp DNA Ladders are premixed with loading buffer and formulated specifically for maximum performance on E-Gel® EX gels as well as other E-Gel® precast gels. Standard ladders not premixed with loading buffer may also be used, but in significantly lower amounts than required for other gels. Invitrogen’s 0.1-2 Kb and 0.5-10Kb RNA ladders may be used when separating RNA samples.

Running and viewing apparatus
E-Gel® EX gels require the E-Gel® iBase™ Power System running apparatus and the E-Gel® Safe Imager™ Real-Time Transilluminator for real time viewing of sample migration.

Pack sizes
E-Gel® EX 4% gels are offered as a pack of 10 gels.
