Biological Buffers
Biological buffers are inert and have short-term effects on the system under investigation, both of which are distinct advantage over inorganic substances and weak organic acids that were used in the past. Most biological buffers in use today are N-substituted taurine or glycine buffers, which meet most of the requirements that biological buffers have to fulfill. Buffer systems are usually used for experiments to enable direct comparison of results.

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.
