Taw qhia
N-(2-hydroxyethyl) hexamethylenediamine. Nws yog xim tsis muaj xim crystalline khoom nrog siab solubility thiab stability. Cov hauv qab no yog cov lus qhia txog qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb ntawm HEPES:
【Properties】
HEPES yog ib qho tsis muaj zog alkaline tsis muaj qhov tsis zoo ntawm pH 6.8-8.2. Nws dissolves zoo hauv dej thiab tsis yooj yim cuam tshuam los ntawm enzymes thiab acids secreted los ntawm cov hlwb.
【Application】
HEPES yog dav siv nyob rau hauv biochemistry thiab molecular biology. Nws yog tsuas yog siv los ua lub cev tsis muaj zog rau cov kab lis kev cai ntawm tes xov xwm thiab tsis yog rau cov tshuaj tiv thaiv catalytic ntawm enzymes thiab cov protein. HEPES kuj tseem siv tau rau electrophoresis sib cais ntawm DNA thiab RNA, fluorescent staining, enzyme kev soj ntsuam thiab lwm yam kev sim ua haujlwm.
【Txoj Kev】
HEPES tuaj yeem ua ke los ntawm cov tshuaj tiv thaiv ntawm 6-chlorohexamethylenetriamine nrog 2-hydroxyacetic acid. Cov txheej txheem npaj tshwj xeeb yog raws li hauv qab no:
1. Dissolve 6-chlorohexamethylenetriamine nyob rau hauv sodium hydroxide tov los tsim sodium ntsev ntawm triamine.
2. 2-Hydroxyacetic acid ntxiv rau daim ntawv N-(2-hydroxyethyl) hexamethylenediamine.
3. Cov khoom yog crystallized thiab purified kom tau HEPES ntshiab.
【Safety Information】
1. Tsis txhob kov qhov muag thiab daim tawv nqaij ncaj qha, yaug tam sim nrog dej kom ntau yog tias kov tsis tau.
2. Thaum siv thiab khaws cia, tsis txhob sib cuag nrog oxidants, organic teeb meem thiab muaj zog acids kom tsis txhob muaj kev phom sij txaus ntshai.
3. Thaum ua haujlwm, xyuam xim rau kev tiv thaiv tus kheej, hnav tsom iav kev nyab xeeb, hnab looj tes tiv thaiv thiab cov khaub ncaws hauv chav kuaj. Ua haujlwm nyob rau hauv qhov chaw ua haujlwm zoo ventilated.
4. Nws yog nruj me ntsis txwv tsis pub noj, nqus los yog qhia rau hauv lub plab zom mov. Thov ua tib zoo saib xyuas kev nyab xeeb thaum siv.
