HEPES Buffer
HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) is a cornerstone in biological and biochemical research, renowned for its exceptional buffering capabilities. Its zwitterionic nature and a pKa close to physiological pH make it an ideal choice for maintaining stable pH in demanding applications. Unlike bicarbonate buffers, HEPES is CO2-independent, offering enhanced stability in open systems or when CO2 incubators are not feasible. This makes it indispensable for ensuring cell culture media pH control and consistent biological buffer pH stability in a wide array of life science experiments.
- Discover superior cell culture media pH control with HEPES, a vital component for maintaining the delicate physiological pH required for optimal cell growth and metabolic activity.
- Leverage the inherent stability of zwitterionic buffer research applications, as HEPES minimizes pH fluctuations, thereby enhancing the reliability of experimental outcomes.
- Understand the critical HEPES pKa value of approximately 7.3-7.5, which is key to its effectiveness in buffering biological systems near neutral pH, ensuring consistent performance across various biological experiments.
- Benefit from CO2 independent cell culture capabilities, allowing for stable pH maintenance even outside of a CO2 incubator, which is crucial for extended cell manipulations and cryopreservation.
