HEPES CAS 7365-45-9 ndi chiyani?

HEPES CAS 7365-45-9 yafotokozedwa kuti ndi imodzi mwazinthu zabwino kwambiri zosungiramo zolinga zonse zomwe zilipo pakufufuza kwachilengedwe. Pa biological pH, molekyuyo ndi zwitterionic, ndipo imagwira ntchito ngati chitetezo pa pH 6.8 mpaka 8.2 (pKa 7.55). Amagwiritsidwa ntchito m'maselo amtundu pakati pa 5mM mpaka 30 mM. HEPES yakhala ikugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza chikhalidwe cha minofu. Nthawi zambiri amagwiritsidwa ntchito kubisa media media mumlengalenga. HEPES imapeza kugwiritsidwa ntchito kwake mu kuyesa kwa in vitro pa Mg.

Kugwiritsa ntchito

Zopanda poizoni ku cell. Amagwiritsidwa ntchito ngati hydrogen ion buffer, yomwe imatha kuwongolera kuchuluka kwa pH kosalekeza kwa nthawi yayitali. Mlingo wa mankhwalawa ndi 10-50 mmol / L. Nthawi zambiri, 20mmol/LHEPES muzakudya zopatsa thanzi zimatha kukhala ndi buffer.
