缓冲（液）
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.

IPG buffers
Supplier: GE HEALTHCARE
IPG buffers are ampholyte-containing buffer concentrates specifically formulated for use with Immobiline™ DryStrip gels for isoelectric focusing, run as the first dimension of 2-D electrophoresis or as a separate application. Using Immobiline DryStrip gels together with matching IPG buffer gives high sample loading capacity, improves resolution, and increases the probability of detecting low abundance proteins.
