Mawu Oyamba
N-(2-hydroxyethyl) hexamethylenediamine. Ndi mtundu wa crystalline wolimba wokhala ndi kusungunuka kwakukulu komanso kukhazikika. Zotsatirazi ndikuwulula za chilengedwe, kugwiritsa ntchito, kukonzekera ndi chitetezo cha HEPES:
【Katundu】
HEPES ndi chotchinga chofooka cha alkaline chokhala ndi buffer osiyanasiyana pH 6.8-8.2. Amasungunuka bwino m'madzi ndipo samakhudzidwa mosavuta ndi ma enzyme ndi ma acid omwe amapangidwa ndi maselo.
【Mapulogalamu】
HEPES imagwiritsidwa ntchito kwambiri pazasayansi yazachilengedwe komanso sayansi yamamolekyulu. Amagwiritsidwa ntchito kwambiri ngati chitetezo chamthupi cha cell culture media komanso chotchingira chothandizira ma enzymes ndi mapuloteni. HEPES itha kugwiritsidwanso ntchito pakulekanitsa kwa electrophoresis kwa DNA ndi RNA, utoto wa fulorosenti, kusanthula kwa enzyme ndi ntchito zina zoyesera.
【Njira】
HEPES ikhoza kupangidwa ndi zomwe 6-chlorohexamethylenetriamine ndi 2-hydroxyacetic acid. Kukonzekera kwapadera kuli motere:
1. Sungunulani 6-chlorohexamethylenetriamine mu sodium hydroxide solution kupanga sodium mchere wa triamine.
2. 2-Hydroxyacetic acid amawonjezeredwa kuti apange N- (2-hydroxyethyl) hexamethylenediamine.
3. Mankhwalawa amapangidwa ndi crystallized ndi kuyeretsedwa kuti apeze HEPES yoyera.
【Zidziwitso Zachitetezo】
1. Pewani kukhudzana mwachindunji ndi maso ndi khungu, sukani mwamsanga ndi madzi ambiri ngati mwakhudza mosadziwa.
2. Mukamagwiritsa ntchito ndikusunga, pewani kukhudzana ndi okosijeni, zinthu zakuthupi ndi ma asidi amphamvu kuti mupewe ngozi.
3. Mukamagwira ntchito, samalani za chitetezo chaumwini, valani magalasi otetezera, magolovesi otetezera ndi zovala za labotale. Gwirani ntchito pamalo olowera mpweya wabwino wa labotale.
4. Ndizoletsedwa kudya, kutulutsa mpweya kapena kuyambitsa m'mimba. Chonde sungani ukhondo wa labotale mukamagwiritsa ntchito.
