EZ Pack™ Agarose Tablets

• Eliminates weighing
• Fast dissolving, just two minutes
• Environmentally friendly, free from organic solvents
• Consistent, reproducible gels
• Enhanced resolution and clarity 

Researchers trust Benchmark’s Agarose LE to meet their electrophoretic needs for various applications. Now, the same agarose is available in a convenient, no-mess tablet.

Agarose LE is refined in an advanced process that excludes the use of organic solvents. The result is a cleaner end product with significantly reduced environmental impact. The agarose can be used for analyses of nucleic acids from 150 bp to 25,000 bp, protein electrophoresis, and various blotting protocols.

The low EEO of the agarose promotes increased electrophoretic mobility, yielding improved resolution and shorter run times. This also allows macromolecules and larger particles (subcellular fragments, viruses, etc.) to migrate more freely through the gel matrix. The consistently low EEO reduces band distortion (caused by counterflow) that can result from the presence of excessive sulfate-rich negative ions. The quick-dissolving EZ Pack™ tablet contains 0.5 g (500 mg) of Agarose LE, eliminating the hands-on time and inaccuracies normally associated with weighing. Use of the tablet is not only convenient and cleaner, but it also provides better consistency and reproducibility gel to gel.

Gel preparation is simple – add the desired number of tablets to the electrophoresis buffer, allow it to sit for two minutes, and then heat and pour as usual. The resulting gels are highly transparent, have exceptional thermal stability (ensuring safe and easy handling), and exhibit exceptionally low absorption of chemical staining agents.

EZ Pack™ Agarose Tablets are supplied in convenient blister packs for safe, clean dispensing.
