Gabatarwa
N- (2-hydroxyethyl) hexamethylenediamine. Yana da m crystalline mara launi tare da babban solubility da kwanciyar hankali. Mai zuwa shine gabatarwa ga yanayi, amfani, shiri da bayanan aminci na HEPES:
Properties】
HEPES ne mai raunin alkaline mai rauni tare da kewayon buffer na pH 6.8-8.2. Yana narkewa da kyau a cikin ruwa kuma ba a sauƙaƙe ta hanyar enzymes da acid ɗin da sel suka ɓoye.
【Aikace-aikace】
Ana amfani da HEPES sosai a fagagen nazarin halittu da ilmin halitta. Ana amfani da shi galibi azaman ma'ajin ilimin lissafi don kafofin watsa labarai na al'adar tantanin halitta da ma'auni don haɓaka halayen enzymes da sunadarai. Hakanan ana iya amfani da HEPES don rabuwar electrophoresis na DNA da RNA, tabo mai kyalli, nazarin ayyukan enzyme da sauran ayyukan gwaji.
【Hanyar】
Ana iya haɗa HEPES ta hanyar amsawar 6-chlorohexamethylenenetriamine tare da 2-hydroxyacetic acid. Tsarin shiri na musamman shine kamar haka:
1. Narke 6-chlorohexamethylenenetriamine a cikin maganin sodium hydroxide don samar da gishiri na sodium na triamine.
2. 2-Hydroxyacetic acid an kara don samar da N- (2-hydroxyethyl) hexamethylenediamine.
3. Samfurin yana crystallized da tsarkakewa don samun HEPES mai tsabta.
【Bayanin Tsaro】
1. Guji saduwa kai tsaye da idanu da fata, kurkura nan da nan da ruwa mai yawa idan an taɓa shi ba da gangan ba.
2. Lokacin amfani da adanawa, kauce wa hulɗa da oxidants, kwayoyin halitta da kuma acid mai karfi don hana halayen haɗari.
3. Lokacin aiki, kula da kariya ta sirri, sa gilashin aminci, safar hannu masu kariya da tufafin dakin gwaje-gwaje. Yi aiki a cikin kyakkyawan yanayin dakin gwaje-gwaje.
4. An haramta cin abinci, shaka ko shigar da shi cikin tsarin narkewar abinci. Da fatan za a kula da tsaftar dakin gwaje-gwaje yayin amfani.
