Sterile Endotoxin Free pH - 8.0 Tris EDTA, commonly known as TE Buffer, is synonymous with storage and solubilization of DNA, cDNA, and RNA. Though primarily a pH buffer, it is also a protective agent for the purified nucleic acids due to the presence of the chelating agent EDTA, which inactivates...

Synonyms: TAE buffer Application: TAE running buffer is the most commonly used buffer for DNA agarose gel electrophoresis but is also used for non-denaturing RNA agarose gel electrophoresis. Double-stranded DNA tends to run faster in TAE than in other buffers but can also become exhausted during...
