CAS NO : 5625-37-6 EC NO : 227-057-6 MF : C8H18N2O6S2 MW : 302.36 Specification : White Powder Packing : 500g/bottle Product description : PIPES (piperazine N, N ` di (2-ethanesulfonic acid)) is a zwitterionic buffer with a buffering pH range of 7.2-7.4. It is insoluble in water but soluble in sodium hydroxide aqueous solution. PIPES is included in Good's buffer and is widely used in vaccine production, tissue culture, cationic efficacy research, and separation techniques for biological substances. Basic introduction of PIPES buffer PIPES is different from other buffering agents, such as BIS-TRIS and BICINE, as it cannot form stable compounds with many metal ions, making it very suitable as a buffering agent in metal ion solutions. There are two pKa values for PIPES, namely 1pKa and 2.67pKa. 1pKa is 6.76 at ambient temperature of 25 ° C, close to physiological pH, with a buffer range of 6.1-7.5, which is suitable for cell culture work. 2.67pKa has a buffer range of 1.5-3.5 at 25 ° C. Where can PIPES be applied PIPES can be used to purify tubulin by cellulose phosphate chromatography and recombinant GTP by gel filtration, which can bind proteins ARF1 and ARF2 to crystallize transketolase from Escherichia coli as a buffer. However, it is worth noting that PIPES is not suitable for redox systems as it can form free radicals. The advantages of PIPES buffer 1. The fixation of glutaraldehyde in animal and plant tissue samples can lead to lipid loss with significant morphological changes. When using PIPES buffered glutaraldehyde fixative, lipid loss and artifacts are minimized. 2. If immobilized in oxalate buffered glutaraldehyde for supercellular chemical fixation, it is possible to selectively lose the activity of alkaline phosphatase. When using PIPES as a buffer, the activity retention rate will be significantly improved. 3. The combination of glutaraldehyde and formaldehyde in PIPES buffer can achieve excellent fixation of fungal spores under fluorescence and electron microscopy.
