Hoʻolauna
N-(2-hydroxyethyl)hexamethylenediamine. He paʻa kala kala ʻole me ka solubility kiʻekiʻe a me ka paʻa. Eia ka hoʻolauna ʻana i ke ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana o HEPES:
【Waiwai】
ʻO ka HEPES kahi mea hoʻopaʻa alkaline nāwaliwali me kahi pae pale o ka pH 6.8-8.2. Hoʻoheheʻe maikaʻi ia i ka wai a ʻaʻole maʻalahi i ka hopena e nā enzymes a me nā waikawa i huna ʻia e nā cell.
【Nā noi】
Hoʻohana nui ʻia ʻo HEPES ma ka ʻoihana biochemistry a me ka molecular biology. Hoʻohana nui ʻia ia ma ke ʻano he physiological buffer no ka media moʻomeheu cell a me kahi pale no nā hopena catalytic o nā enzymes a me nā protein. Hiki ke hoʻohana ʻia ʻo HEPES no ka hoʻokaʻawale electrophoresis o DNA a me RNA, fluorescent staining, enzyme activity analysis a me nā hana hoʻokolohua ʻē aʻe.
【Meʻa】
Hiki ke hoʻopili ʻia ka HEPES e ka hopena o ka 6-chlorohexamethylenetriamine me ka 2-hydroxyacetic acid. ʻO ke kaʻina hana hoʻomākaukau kūikawā penei:
1. E hoʻoheheʻe i ka 6-chlorohexamethylenetriamine i loko o ka solution sodium hydroxide e hana i ka paʻakai sodium o ka triamine.
2. Hoʻohui ʻia ka 2-Hydroxyacetic acid e hana i ka N-(2-hydroxyethyl)hexamethylenediamine.
3. Hoʻopili ʻia ka huahana a hoʻomaʻemaʻe ʻia no ka loaʻa ʻana o HEPES maʻemaʻe.
【ʻike palekana】
1. E pale i ka pili pono me ka maka a me ka ili, e holoi koke me ka wai nui ke hoopa wale ia.
2. I ka hoʻohana ʻana a mālama ʻana, e pale aku i ka hoʻopili ʻana me nā mea ʻokiʻoki, nā mea ola a me nā ʻakika ikaika e pale ai i nā hopena pōʻino.
3. I ka wā e hana ai, e hoʻolohe i ka pale pilikino, e hoʻokomo i nā aniani palekana, nā mīkina lima pale a me nā lole hale hana. E hana i loko o kahi keʻena hoʻokolohua maikaʻi-ventilated.
4. ʻAʻole loa e ʻai, hoʻoulu a hoʻokomo i loko o ka ʻōnaehana digestive. E ʻoluʻolu e mālama i ka hoʻomaʻemaʻe keʻena hana maikaʻi i ka wā e hoʻohana ai.
