Descrição

Aplicação

TBE running buffer is the most commonly used buffer for DNA and RNA polyacrylamide gel electrophoresis. TBE is used with non-denaturing or denaturing (7 M urea) gels. It is also routinely used for DNA automated sequencing gel. TBE can also be used for agarose gels but is not recommended for preparative gels for recovery of nucleic acids.
Dilution of the TBE stock concentrates to a 1× TBE running buffer results in a buffer containing 89 mM Tris-borate and 2 mM EDTA, pH 8.3. The 5× or 10× stocks may also be added to an acrylamide/bis-acrylamide stock solution for making the PAGE gel. Applied voltages of less than 5 V/cm (distance between the electrodes of the unit) are recommended for maximum resolution.

Tris-Borate-EDTA buffer is suitable for use in gel electrophoresis.
It may be employed for the following studies:

• As buffer system for the evaluation of molecular weights of glycoproteins of ovalbumin, avidin and fetuin by sodium dodecyl sulfate-pore gradient electrophoresis.
• For the hemoglobin electrophoresis in starch gel.
• Preparation of buffer concentration gradient gel for the rapid determination of DNA sequence.
