Invitrogen E-Gel EX Double Comb precast agarose gels are designed for ultrasensitive and convenient DNA sample electrophoresis in as little as 5–8 minutes. Each E-Gel EX Double Comb gel cassette contains all components and stain required for efficient gel separation and analysis—just load your samples and run. E-Gel EX Double Comb gels are ideal for analyzing PCR products, restriction digests, plasmid preparations, and genotyping samples.

Features of E-Gel EX Double Comb Agarose Gels include:
• Instantaneous setup—precast E-Gel agarose gels are ready for use when you are, and do not require gel preparation or additional buffers
• High sensitivity—detect 1 ng of sample DNA
• Rapid analysis—complete DNA sample separation in 5–8 minutes
• In-process control—view DNA sample migration in real time
• Easy sample access—openable cassette design allows easy in-gel access for convenient DNA sample excision or transfer to membranes
• For DNA—ideal for DNA sample analysis

Ultra-sensitive detection of DNA
E-Gel EX Double Comb gels include SYBR Gold DNA stain and were developed for ultimate sensitivity, demonstrating up to five-fold greater sensitivity than comparable gels containing ethidium bromide. This superior sensitivity allows you to use lower amounts of sample, saving time and money.

Fast and convenient analysis
E-Gel EX Double Comb gels are our fastest-resolving agarose gels, enabling sample analysis in as little as 5-8 minutes. Each E-Gel EX Double Comb gel contains agarose, electrodes, SYBR Gold DNA stain, and a bufferless ion exchange system packaged inside a dry disposable cassette. E-Gel technology does not required any gel or buffer preparation or gel staining steps. Just load your samples and run.

Live monitoring of DNA migration
E-Gel EX Double Comb gels include SYBR Gold II DNA gel stain with an excitation wavelength in the blue-light spectrum. When used on the E-Gel Power Snap Electrophoresis Device with integrated blue-light trans-illuminator, less-hazardous real-time monitoring of DNA migration is enabled without risk to eyes or possible damage of the sample, unlike UV illumination.

Easy access to the gel
E-Gel EX Double Comb cassettes are designed for convenient opening with a Gel Knife (Cat. No. EI9010), for easy excision of specific bands or transfer of the gel to a membrane for southern blot analysis.
