Boric buffer
WebGeneral description. TBE (Tris/Borate/EDTA) Buffer is commonly used in nucleic acid electrophoresis. This solution is effective under slightly basic conditions, which keeps DNA deprotonated, water-soluble, and protected from degradation. This concentrate can be easily diluted to 1x or 0.5x before use (with molecular biology grade water). 1 2. WebJul 12, 2024 · Preparation for the 10X TBE Electrophoresis Buffer. Dissolve the Tris, boric acid, and EDTA in 800 ml of deionized water. Dilute the buffer to 1 L. Undissolved white clumps may be made to dissolve by placing the bottle of solution in a hot water bath. A magnetic stir bar can aid the process.
