Descripción general

1, 4-piperazinediethanesulfonic acid (PIPES) is a zwitterionic buffer that belongs to the group of the ethanesulfonic acid buffer series, first introduced by Good et al., It is a non-toxic buffer used in cell culture and tissue fixation for electron microscopy and other biological applications. PIPES don’t interact with metal ions. Since its pKa at 37°C is near physiological pH, it has been used as a buffering substance in biological, biochemical, and environmental studies. PIPES is developed to meet certain criteria: midrange pKa, maximum water solubility and minimum solubility in all other solvents, minimal salt effects, minimal change in pKa with temperature, chemically and enzymatically stable, minimal absorption in visible or UV spectral range and easily synthesized. Buffers can be prepared by adding a solution of the 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.

Aplicación

PIPES sodium salt buffer has been used:

  • to prepare BRB80 buffer for imaging dynamic microtubules and single kinesin molecules through fluorescence microscopy
  • as a component of PEM fixation solution
  • to reconstitute red blood cells (RBCs) to study the effect of pH on 5-coordinate alpha-nitrosyl-hemoglobin (HbNO) stability

Características y beneficios

  • Non-toxic
  • Easy to use
  • Thermally stable
  • Easy to handle and store

Increased osmotic pressure has been reported to cause non-cytotoxic histamine release (HR) from human basophils, as well as a potentiation of HR induced by anti-IgE. In this study, the effects of hyperosmolar Na-K-acetate (300-600 mOsm/kg H2O) on HR was studied

Maximal rates of renal hydrogen ion secretion and bicarbonate reabsorption in the dogfish were stimulated by intravascular infusion of acidic and basic buffers: bicarbonate, phosphate, phenol red, dimethadione (DMO), imidazole, and piperazine-N,N'-bis(2 ethanesulfonic acid) (PIPES). There was no difference in

In cultures of Desulfovibrio desulfuricans 620 the effects of iron(III) (hydr)oxides (hematite, goethite, and ferrihydrite) on microbial reduction and reoxidation of uranium (U) were evaluated under lactate-limited sulfate-reducing conditions. With lactate present, G20 reduced U(VI) in both 1,4-piperazinediethanesulfonate (PIPES) and
