Wakilin Crosslinking don dalilai na N, N'-Methylenebisacrylamide

N, N'-methylene diacrylamide (MBAm ko MBAA)wakili ne mai haɗin kai wanda aka yi amfani da shi wajen ƙirƙirar polymers kamar polyacrylamide. Tsarin kwayoyin sa shine C7H10N2O2, CAS: 110-26-9, kaddarorin: farin crystalline foda, mai narkewa cikin ruwa, kuma mai narkewa a cikin ethanol, acetone da sauran kaushi na halitta. Diacrylamide wani fili ne na gel polyacrylamide (na SDS-PAGE) wanda za'a iya amfani dashi a cikin nazarin halittu. Diacrylamide polymerizes tare daacrylamidekuma yana iya ƙirƙirar haɗin giciye tsakanin sarƙoƙin polyacrylamide, don haka samar da hanyar sadarwa ta polyacrylamide maimakon madaidaiciyar layin da ba a haɗa ba.polyacrylamidesarƙoƙi.

Wakilin Crosslinking
A cikin ilmin sunadarai da ilmin halitta, crosslinking shine haɗin gwiwa wanda ke haɗa sarkar polymer zuwa wani. Waɗannan hanyoyin haɗin za su iya ɗaukar nau'ikan haɗin gwiwar covalent ko ionic, kuma polymer na iya zama na roba ko na halitta (misali furotin).
A cikin sinadarai na polymer, "crosslinking" yawanci yana nufin yin amfani da haɗin kai don inganta canje-canje a cikin abubuwan da ke cikin jiki na polymer.
Lokacin da aka yi amfani da "crosslinking" a fagen ilimin halitta, yana nufin amfani da bincike don haɗa sunadaran tare don bincika hulɗar furotin da furotin da sauran sababbin hanyoyin haɗin kai.
Ko da yake ana amfani da kalmar don nufin "haɗin sarƙoƙin polymer" a cikin duka kimiyyar biyu, matakin ƙetare da ƙayyadaddun wakili na haɗin gwiwar ya bambanta sosai. Kamar yadda yake tare da duk ilimin kimiyya, akwai zobe, kuma bayanin da ke gaba shine mafari don fahimtar waɗannan nuances.

Polyacrylamidegel electrophoresis
Polyacrylamide gel electrophoresis (PAGE) wata dabara ce da ake amfani da ita sosai a cikin ilimin kimiyyar halittu, bincike-bincike, ilimin gado, ilmin halitta, da fasahar kere kere don rarrabuwar macromolecules na halitta (yawanci sunadarai ko acid nucleic) dangane da motsin electrophoretic. Motsi na Electrophoretic aiki ne na tsawon kwayoyin halitta, daidaituwa, da caji. Polyacrylamide gel electrophoresis kayan aiki ne mai ƙarfi don nazarin samfuran RNA. Lokacin da polyacrylamide gel aka denatured bayan electrophoresis, yana bayar da bayanai game da abun da ke ciki na RNA irin samfurin.

Sauran amfanin N,N'-methylene diacrylamide
N, N'-methylene diacrylamide a matsayin sinadarai reagent yana da aikace-aikace da yawa, yana da ruwa mai fashewa, resin superabsorbent, wakili mai toshe ruwa, abubuwan da aka ƙara, barasa mai narkewa mai haske na nailan guduro, ruwan magani flocculant kira na wani muhimmin ƙari, Hakanan wakili ne mai kyau na shayar da ruwa da mai riƙe ruwa, ana amfani dashi wajen kera resin superabsorbent da haɓaka ƙasa, Hakanan ana amfani dashi don daukar hoto, bugu, yin faranti, da sauransu.
