Nhanganyaya
N-(2-hydroxyethyl) hexamethylenediamine. Iyo isina ruvara crystalline yakasimba ine yakakwirira solubility uye kugadzikana. Iyi inotevera sumo kune chimiro, kushandiswa, kugadzirira uye kuchengetedza ruzivo rweHEPES:
【Zvinhu】
HEPES ibuffer ine alkaline isina simba ine buffer range yepH 6.8-8.2. Inonyungudika zvakanaka mumvura uye haisi nyore kukanganiswa ne enzymes uye acids yakavanzwa nemasero.
【Zvishandiso】
HEPES inoshandiswa zvakanyanya muminda yebiochemistry uye molecular biology. Inonyanya kushandiswa se physiological buffer ye cell tsika midhiya uye buffer ye catalytic maitiro ema enzymes nemapuroteni. HEPES inogona zvakare kushandiswa kuparadzanisa electrophoresis yeDNA neRNA, fluorescent staining, enzyme chiitiko chekuongorora uye mamwe maitiro ekuedza.
【Nzira】
HEPES inogona kugadzirwa nekuita kwe6-chlorohexamethylenetriamine ine 2-hydroxyacetic acid. Iyo chaiyo yekugadzirira maitiro ndeaya anotevera:
1. Dissolve 6-chlorohexamethylenetriamine mu sodium hydroxide solution kugadzira sodium munyu we triamine.
2. 2-Hydroxyacetic acid inowedzerwa kuita N- (2-hydroxyethyl) hexamethylenediamine.
3. Chigadzirwa chacho chakanatswa uye chinonatswa kuti chiwane HEPES yakachena.
【Ruzivo rwekuchengetedzwa】
1. Dzivisa kuonana zvakananga nemaziso uye ganda, sukurudza pakarepo nemvura yakawanda kana wakabatwa zvisina kufanira.
2. Paunenge uchishandisa nekuchengetedza, dzivisa kusangana neoxidants, organic matter uye yakasimba acids kudzivirira maitiro ane ngozi.
3. Paunenge uchishanda, teerera kuchengetedzwa kwemunhu, pfeka magirazi ekuchengetedza, magirovhosi ekudzivirira uye zvipfeko zve laboratori. Shanda munzvimbo ine mhepo inofefetera murabhoritari.
4. Inorambidzwa zvachose kudya, kufemesa kana kupinza mukati mekudya. Ndapota chengetedza hutsanana hwerabhoritari panguva yekushandiswa.
