Iimpawu ezinobungozi | C – Iyadleka |
Iikhowudi zoMngcipheko | I-R34 – Ibangela ukutsha I-R21/22 – Iyingozi xa udibana nolusu kwaye ukuba uginyiwe. |
Inkcazelo yoKhuseleko | S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S36/37/39 – Nxiba iimpahla ezikhuselayo ezifanelekileyo, iiglavu kunye nokhuseleko lwamehlo/ubuso. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. |

Intshayelelo
N-(2-hydroxyethyl) hexamethylenediamine. Yikristale engenambala eqinileyo ene-solubility ephezulu kunye nokuzinza. Oku kulandelayo kukwazisa ngobume, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwe-HEPES:
【iipropati】
I-HEPES sisithinteli se-alkaline esibuthathaka esinoluhlu lwe-buffer lwe-pH 6.8-8.2. Inyibilika kakuhle emanzini kwaye ayichatshazelwa lula yi-enzymes kunye ne-asidi efihliweyo ngamaseli.
【Iinkqubo】
I-HEPES isetyenziswa kakhulu kwiinkalo zebhayoloji nakwibhayoloji yemolekyuli. Isetyenziswa ikakhulu njengesithinteli somzimba kumajelo eendaba enkcubeko yeeseli kunye nesithinteli sokusabela okubangela ii-enzymes kunye neeproteni. I-HEPES ingasetyenziselwa ukwahlula i-electrophoresis ye-DNA kunye ne-RNA, i-fluorescent staining, uhlalutyo lomsebenzi we-enzyme kunye neminye imisebenzi yokulinga.
【Indlela】
I-HEPES inokwenziwa ngokuphendula kwe-6-chlorohexamethylenetriamine kunye ne-2-hydroxyacetic acid. Inkqubo yolungiselelo ethile imi ngolu hlobo lulandelayo:
1. Dissolve i-6-chlorohexamethylenetriamine kwisisombululo se-sodium hydroxide ukuvelisa ityuwa ye-sodium ye-triamine.
2. I-2-Hydroxyacetic acid yongezwa kwi-N- (2-hydroxyethyl) i-hexamethylenediamine.
3. Imveliso icwecwe kwaye ihlanjululwe ukufumana i-HEPES ecocekileyo.
【Ulwazi loKhuseleko】
1. Kuphephe ukudibana ngqo namehlo kunye nolusu, hlambulula ngokukhawuleza ngamanzi amaninzi ukuba uchukumise ngokungaqondanga.
2. Xa usebenzisa kwaye ugcina, thintela ukudibana nee-oxidants, izinto eziphilayo kunye ne-acids ezinamandla ukukhusela ukuphendula okuyingozi.
3. Xa usebenza, nikela ingqalelo ekukhuseleni komntu, nxiba iiglasi zokhuseleko, iiglavu ezikhuselayo kunye nempahla yebhubhoratri. Sebenza kwindawo yelabhoratri engena umoya.
4. Kunqatshelwe ngokungqongqo ukutya, ukuphefumla okanye ukungenisa kwinkqubo yokugaya. Nceda ugcine ucoceko lwebhubhoratri elungileyo ngexesha lokusetyenziswa.
