Product Description

Introduction:
1, 4 - Piperazinediethanesulfonicacid, abbreviated as PIPES, the Chinese called 1-4 - piperazine ethyl sulfonic acid, is the 1960 's by one of the Good development of ethyl sulfonic acid series such as buffer reagents, with a Good' s buffer has some important characteristics, including: 1) low UV (λ≥260nm) absorbance; 2) Water solubility is the strongest, while the solubility in other solvents is the lowest; 3) pKa was in the neutral range and was not susceptible to temperature; 4) the pH value was stable; 5) small interference reaction, enzyme or chemical stability; 6) Easy synthesis. The effective buffer range of PIPES was pH6.1-7.5, pKa=6.8 (25ºC). Since its pKa is close to physiological pH, it is suitable for cell culture. In addition, PIPES can also be used as a buffer to minimize lipid damage and experimental artifacts caused by glutaraldehyde fixation in animal and plant chemistry.
