Ambion® Agarose-LE™ (General Use) is a high-purity, functionally tested, general use agarose suitable for routine nucleic acid electrophoresis. It has a low electroendosmosis value (EEO -mr 0.103) ensuring high electrophoretic mobility of nucleic acids. It is supplied in one bottle of 100 g. Because of the high gel strength, easy-to-handle gels can be prepared with this agarose, at concentrations as low as 0.5%. This can improve the separation of larger DNA fragments (10–20 kb) over conventional electrophoresis techniques.
