Thermo Scientific 50X TAE Buffer (Tris-acetate-EDTA) is used for electrophoresis of nucleic acids in agarose and polyacrylamide gels. You can use this buffer for both genomic and large supercoiled DNA, and you can also use this as both a running and a gel preparation buffer.


• Electrophoresis of nucleic acids in agarose and polyacrylamide gels
• Used both as a running buffer and as a gel preparation buffer
• Filtered through a 0.22 µm membrane
• Recommended for resolution of RNA and DNA fragments larger than 1500 bp, for genomic DNA and for large supercoiled DNA

TAE buffer has a relatively low buffering capacity. Therefore, periodic replacement of the buffer during prolonged electrophoresis is recommended.
For Research Use Only. Not for use in diagnostic procedures.
