TBE Buffer, 10x stock solution (liquid) (MB27701)


1000 mL


Description: In molecular biology, TBE and TAE buffers are used for agarose and polyacrylamide gel electrophoresis. TBE (Tris-Borate-Acetate) buffer is suitable when analysing DNA fragments from PCR amplification, DNA isolation protocols, or DNA cloning experiments. It is adapted for separating smaller DNA fragments (less than 1500 bp on a 0.8% agarose gel). TBE has a greater buffering capacity and will give sharper resolution than TAE. However, TBE gels in general afford a poor recovery of nucleic acids compared with TAE gels.
