Waa maxay HEPES CAS 7365-45-9?

HEPES CAS 7365-45-9 waxaa lagu tilmaamay inay tahay mid ka mid ah kaydinta ujeeddooyinka oo dhan ugu wanaagsan ee loo heli karo cilmi-baarista bayoolajiga. Marka pH-ga noolaha ah, molecule-ku waa zwitterionic, wuxuuna wax ku ool u yahay kaydiye ahaan pH 6.8 ilaa 8.2 (pKa 7.55). Caadi ahaan waxaa loo adeegsadaa dhaqanka unugyada marka la eego inta u dhaxaysa 5mM ilaa 30 mM. HEPES waxaa loo adeegsaday codsiyo kala duwan oo kala duwan, oo ay ku jiraan dhaqanka nudaha. Waxa caadi ahaan loo isticmaalaa in lagu xidho warbaahinta dhaqanka unugga hawada. HEPES waxay adeegsigeeda ka heshaa tijaabooyinka in vitro ee Mg.
