HEPPS (CAS 16052-06-5)

HEPPS, or N-(2-Hydroxyethyl)piperazine-N′-(3-propanesulfonic acid), is a zwitterionic buffering agent commonly used in biochemical and molecular biology research. Its mechanism of action is rooted in its ability to maintain a stable pH environment, crucial for various enzymatic reactions and protein studies. HEPPS is especially favored for its buffering capacity in the physiological pH range, typically between pH 6.8 and 8.2, making it ideal for biological assays and cell culture experiments. This compound is extensively utilized in the preparation of cell culture media, where maintaining a consistent pH is essential for cell viability and growth. Additionally, HEPPS is employed in biochemical assays, such as enzyme kinetics studies, where precise pH control is necessary for accurate measurement of enzymatic activity. Furthermore, HEPPS has found applications in molecular biology techniques, including nucleic acid purification, PCR (polymerase chain reaction), and protein analysis by SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis). Its compatibility with various biological systems and stability under physiological conditions make HEPPS a valuable tool in research laboratories for maintaining optimal pH conditions and ensuring reliable experimental outcomes in a wide range of biochemical and molecular biology studies.
