Succinate buffer is widely used in biochemical and molecular biology research due to its ability to maintain a stable pH environment, typically around pH 4.0 to 6.0. It is particularly useful in enzymatic assays and protein studies where a slightly acidic pH is required for optimal activity or stability. The buffer is also employed in electrophoresis techniques to ensure consistent pH conditions during the separation of biomolecules. Additionally, succinate buffer finds application in cell culture experiments, where it helps maintain physiological conditions for cell growth and viability. Its compatibility with various biochemical reactions makes it a reliable choice for laboratory applications.
