Usage:
PIPES has pKa (6.76 at 25°C) near the physiological pH which makes it useful in cell culture work. Its effective buffering range is 6.1-7.5 at 25°C. PIPES has been documented minimizing lipid loss when buffering glutaraldehyde histology in plant and animal tissues. Fungal zoospore fixation for fluorescence microscopy and electron microscopy were optimized with a combination of glutaraldehyde and formaldehyde in PIPES buffer. It has a negligible capacity to bind divalent ions.
