Buffers

Resisting pH changes, buffers protect samples when acids or alkali is added. Powder and liquid forms efficiently track proteins during electrophoresis isolation and separation. The salty buffers can also be used to calibrate and standardize pH meters for accurate readings. Blocking substances stop antibody attachment to membrane free sites that would produce an interfering background. In various concentrations to fit any need, the buffers may come in liquids or dehydrated formats.

Buffer, TBE solution 10X concentrate (TRIS-borate-EDTA buffer), Sigma-Aldrich®

Supplier: Merck

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).
