Description
HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) is a widely used zwitterionic buffering agent from the Good’s buffer family, valued for its excellent buffering capacity near physiological pH. With an effective buffering range of pH 6.8–8.2, HEPES is extensively employed in molecular biology, biochemistry, protein chemistry, and cell culture applications where precise pH control is critical.
Proteogenixx’s HEPES Buffer Grade is manufactured to high purity standards, ensuring minimal interference with enzymatic reactions and biological systems. Its strong buffering capacity, low metal ion binding, and chemical stability make it ideal for long-duration experiments, including cell-based assays and protein studies. HEPES is particularly advantageous in CO₂-independent systems, maintaining stable pH even outside incubator environments.
Storage: Store tightly sealed at room temperature in a dry place to ensure long-term stability.
