Iyini i-HEPES CAS 7365-45-9?

I-HEPES CAS 7365-45-9 ichazwe njengesinye sebhafa yenhloso yonke etholakalayo ocwaningweni lwebhayoloji. Ku-pH yebhayoloji, i-molecule iyi-zwitterionic, futhi isebenza kahle njengesigcinalwazi ku-pH 6.8 ukuya ku-8.2 (pKa 7.55). Ngokuvamile isetshenziswa kusiko lwamaseli ekugxiliseni phakathi kuka-5mM kuya ku-30 mM. I-HEPES isetshenziswe ezinhlobonhlobo zezicelo, kuhlanganise nesiko lezicubu. Ivamise ukusetshenziselwa ukuvimba imidiya yesiko lamaseli emoyeni. I-HEPES ithola ukusetshenziswa kwayo ezivivinyweni ze-in vitro ku-Mg.

Isicelo

Ayinabuthi kuseli. Isetshenziswa njenge-hydrogen ion buffer, engalawula uhla lwe-pH olungaguquki isikhathi eside. I-concentration yi-10-50mmol/L. Ngokuvamile, i-20mmol/LHEPES esixazululweni sezakhi ingathola ikhono lebhafa.
