Glycylglycine buffer is widely used in biochemical and molecular biology research due to its effective buffering capacity in the pH range of 7.5 to 8.5. It is particularly valuable in enzyme studies, where maintaining a stable pH is critical for optimal enzyme activity and accurate experimental results. This buffer is also employed in protein purification processes, as it helps stabilize proteins and prevents denaturation during extraction and chromatography. Additionally, glycylglycine buffer is utilized in cell culture applications to maintain a consistent environment for cell growth and viability. Its compatibility with various biological systems makes it a reliable choice for experiments involving nucleic acids, antibodies, and other sensitive biomolecules.
