PIPES, Free Acid [piperazine-N,N′-bis(2-ethanesulfonic acid)] is frequently used as a buffering agent in biochemistry. It is an ethanesulfonic acid buffer developed by Good et al. in the 1960s. PIPES, Free Acid has a pKa near the physiological pH which makes it useful in cell culture work. It has been documented to minimize lipid loss when buffering glutaraldehyde histology in plant and animal tissues. Additional forms available: PIPES, Sesquisodium Salt (sc-216100) PIPES dipotassium salt (sc-258019) PIPES disodium salt (sc-264078) PIPES, Sodium Salt (sc-296097). Buffers can be prepared by adding a solution of base to PIPES, Free Acid, titrating to the appropriate pH, or by mixing equimolar solutions of the monosodium salt and the disodium salt, titrating to the appropriate pH.
