Compared to polyacrylamide gel, agarose has a lower resolution but wider range of separation. Lower grades of agarose can be contaminated with other polysaccharides, salts and proteins. Such impurities can alter the gelling/melting temperature of agarose solutions or affect the ability to use the recovered nucleic acid sample in a post-electrophoresis application.

Two buffers commonly used for DNA agarose electrophoresis are Tris-acetate with EDTA (TAE; 40mM Tris-acetate, 1mM EDTA) and Tris-borate with EDTA (TBE, 89mM Tris-borate, 2mM EDTA). TAE and TBE have different properties, which makes one more suitable than the other for a specific purpose.
Fisher BioReagents provides a wide range of standards, including routine DNA ladders for quick size and quality assessment as well as Fisher Bioreagents™ exACTGene™ DNA ladders that allow for quantitative analysis.
