Yintoni i-HEPES CAS 7365-45-9?

I-HEPES CAS 7365-45-9 ichazwe njengenye yezona zithinteli zenjongo zonke ezifumanekayo kuphando lwebhayoloji. Kwi-pH yebhayoloji, imolekyuli yizwitterionic, kwaye isebenza njengesithinteli kwi-pH 6.8 ukuya ku-8.2 (pKa 7.55). Ngokuqhelekileyo isetyenziswa kwinkcubeko yeeseli ekugxininiseni phakathi kwe-5mM ukuya kwi-30 mM. I-HEPES isetyenziswe kwiintlobo ezahlukeneyo zezicelo, kubandakanywa nenkcubeko yezicubu. Iqhele ukusetyenziselwa ukuthintela imidiya yenkcubeko yeseli emoyeni. I-HEPES ifumana ukusetyenziswa kwayo kwimifuniselo ye-in vitro kuMg.

Isicelo

Ayinatyhefu kwiseli. Isetyenziswa njenge-hydrogen ion buffer, enokulawula udidi lwe-pH olungaguqukiyo ixesha elide. Uxinzelelo ngu-10-50mmol / L. Ngokubanzi, i-20mmol/LHEPES kwisisombululo sezondlo sinokufumana isakhono se-buffer.
