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.

Optimizer Buffer™ for optimal cross-linking and modification

Supplier: G-Biosciences

The conjugation and modification reactions used to cross-link proteins or couple labels to proteins, such as biotin, enzymes, and fluorescent dyes, require certain conditions, including pH and chemical composition for optimal conjugation. Many common buffers routinely used in laboratories have an inhibitory effect on conjugation reactions; for example, Tris buffers inhibit coupling to amines.
