Lintlha tsa Sehlahisoa

Li-tag tsa Sehlahisoa

Matšoao a Kotsi C - E senya
Likhoutu tsa Kotsi R34 – E baka ho cha
R21/22 – E kotsi ha e ama letlalo mme e kwetswe.
Tlhaloso ea Tšireletseho S45 – Ha ho ka etsahala kotsi kapa ha o ikutlwa o sa phele hantle, batla keletso ya bongaka hanghang (bontsha leibole neng kapa neng ha ho kgoneha.)
S36/37/39 - Apara liaparo tse loketseng tsa tšireletso, liatlana le tšireletso ea mahlo / sefahleho.

Selelekela

N-(2-hydroxyethyl)hexamethylenediamine. Ke kristale e se nang 'mala e tiileng e nang le solubility e phahameng le botsitso. Se latelang ke selelekela sa sebopeho, tšebeliso, tokiso le tlhaiso-leseling ea polokeho ea HEPES:

 

【Mehaho】

HEPES ke sekoaelo sa alkaline se fokolang se nang le mefuta e fapaneng ea buffer ea pH 6.8-8.2. E qhibiliha hantle ka metsing 'me ha e amehe habonolo ke li-enzyme le li-acid tse hlahisoang ke lisele.

 

【Lisebelisoa】

HEPES e sebelisoa haholo mafapheng a biochemistry le biology ea limolek'hule. E sebelisoa haholo-holo e le tšireletso ea fisioloji bakeng sa mecha ea litaba ea setso sa lisele le tšireletso bakeng sa karabelo ea li-enzyme le liprotheine. HEPES e ka boela ea sebelisoa bakeng sa karohano ea electrophoresis ea DNA le RNA, litšila tsa fluorescent, tlhahlobo ea ts'ebetso ea enzyme le lits'ebetso tse ling tsa liteko.

 

【Mokhoa】

HEPES e ka etsoa ka karabelo ea 6-chlorohexamethylenetriamine le 2-hydroxyacetic acid. Mokhoa o ikhethileng oa ho itokisa ke o latelang:

1. Hlakola 6-chlorohexamethylenetriamine ka tharollo ea sodium hydroxide ho hlahisa letsoai la sodium ea triamine.

2. 2-Hydroxyacetic acid e kenngoa ho theha N- (2-hydroxyethyl) hexamethylenediamine.

3. Sehlahisoa se hloekisitsoe 'me se hloekisoa ho fumana HEPES e hloekileng.

 

【Lintlha tsa Tšireletso】

1. Qoba ho kopana ka ho toba le mahlo le letlalo, hlatsoa hang-hang ka metsi a mangata haeba u angoa u sa hlokomele.

2. Ha u sebelisa le ho boloka, qoba ho kopana le li-oxidants, lintho tse phelang le li-acid tse matla ho thibela liketso tse kotsi.

3. Ha o sebetsa, ela hloko tšireletso ea botho, roala likhalase tsa tšireletso, liatlana tse sireletsang le liaparo tsa laboratori. Sebetsa sebakeng sa laboratori e nang le moea o motle.

4. E thibetsoe ka ho feletseng ho ja, ho hema kapa ho kenyelletsa tsamaiso ea lijo. Ka kopo, boloka bohloeki bo botle ba laboratori nakong ea tšebeliso.
