He aha ka HEPES CAS 7365-45-9?

Ua wehewehe ʻia ʻo HEPES CAS 7365-45-9 ʻo ia kekahi o nā mea hoʻopaʻa pono āpau i loaʻa no ka noiʻi koolaola. Ma ka pH olaola, he zwitterionic ka mole, a he mea pono ma ke ano he pale ma ka pH 6.8 a i ka 8.2 (pKa 7.55). Hoʻohana maʻamau ia i ka moʻomeheu cell ma ka ʻike ma waena o 5mM a 30 mM. Ua hoʻohana ʻia ʻo HEPES i nā ʻano hana like ʻole, me ka moʻomeheu kiko. Hoʻohana maʻamau ia no ka pale ʻana i ka media moʻomeheu cell i ka ea. Loaʻa iā HEPES kona hoʻohana ʻana i loko o nā hoʻokolohua in vitro ma Mg.
