PIPES Buffer (0.5 M, pH 6.8)

A 0.5 M PIPES buffer optimized for stability at pH 6.8, providing dependable pH regulation across 6.1–7.5. The zwitterionic nature of PIPES reduces ionic interactions, preserving the integrity of biomolecules. It is highly suitable for enzyme assays, protein purification, electrophoresis, and cell‑based experiments where strict pH control is required. PIPES is also valued in microscopy and crystallization for maintaining fine structural detail and reproducibility.
