HEPES CAS 7365-45-9 ni iki?

HEPES CAS 7365-45-9 yasobanuwe nkimwe mubintu byiza byose bigamije kuboneka kubushakashatsi bwibinyabuzima. Kuri biologiya pH, molekile ni zwitterionic, kandi ikora neza nka buffer kuri pH 6.8 kugeza 8.2 (pKa 7.55). Ubusanzwe ikoreshwa mumico ya selile yibanda kuri 5mM kugeza 30 mM. HEPES yakoreshejwe muburyo butandukanye bwo gukoresha, harimo n'umuco wa tissue. Bikunze gukoreshwa muguhuza itangazamakuru ryumuco utugari. HEPES isanga imikoreshereze yayo mubushakashatsi bwa vitro kuri Mg.
