Crosslinking wothandizira zolinga za N,N'-Methylenebisacrylamide

N,N' -methylene diacrylamide (MBAm or MBAA)ndi crosslinking wothandizira ntchito mapangidwe ma polima monga polyacrylamide. Mapangidwe ake a maselo ndi C7H10N2O2, CAS: 110-26-9, katundu: ufa woyera wa crystalline, wosungunuka m'madzi, komanso sungunuka mu ethanol, acetone ndi zina zosungunulira organic. Diacrylamide ndi gulu la polyacrylamide gel (ya SDS-PAGE) yomwe ingagwiritsidwe ntchito mu biochemistry. Diacrylamide polymerize ndiacrylamidendipo imatha kupanga maulalo olumikizirana pakati pa maunyolo a polyacrylamide, ndikupanga maukonde a polyacrylamide m'malo molumikizana ndi mzere wolumikizana.polyacrylamideunyolo.

Crosslinking wothandizira
Mu chemistry ndi biology, crosslinking ndi chomangira chomwe chimalumikiza unyolo wa polima wina ndi mnzake. Maulalo awa amatha kukhala ngati ma covalent kapena ionic bond, ndipo polima amatha kukhala opangidwa kapena achilengedwe (mwachitsanzo mapuloteni).
Mu polima chemistry, "crosslinking" nthawi zambiri amatanthauza kugwiritsa ntchito crosslinking kulimbikitsa kusintha kwa thupi la polima.
Pamene "crosslinking" imagwiritsidwa ntchito m'munda wa biology, imatanthawuza kugwiritsa ntchito ma probes kuti agwirizane ndi mapuloteni kuti awone momwe mapuloteni ndi mapuloteni amagwirira ntchito komanso njira zina zatsopano zolumikizirana.
Ngakhale mawuwa amagwiritsidwa ntchito kutanthauza "kulumikiza maunyolo a polima" mu sayansi yonseyi, kuchuluka kwa kuphatikizika ndi tsatanetsatane wa njira yolumikizira zimasiyana mosiyanasiyana. Monga momwe zilili ndi sayansi yonse, pali kuphatikizika, ndipo kulongosola kotsatiraku ndi poyambira kumvetsetsa ma nuances awa.

Polyacrylamidegel electrophoresis
Polyacrylamide gel electrophoresis (PAGE) ndi njira yomwe imagwiritsidwa ntchito kwambiri mu biochemistry, forensics, genetics, molecular biology, ndi biotechnology pakulekanitsa ma macromolecules achilengedwe (kawirikawiri mapuloteni kapena nucleic acid) potengera kayendedwe kawo ka electrophoretic. Electrophoretic mobility ndi ntchito ya kutalika kwa molekyulu, conformation, ndi charge. Polyacrylamide gel electrophoresis ndi chida champhamvu chosanthula zitsanzo za RNA. Pamene gel osakaniza polyacrylamide ndi denatured pambuyo electrophoresis, amapereka zambiri zokhudza zikuchokera RNA mtundu chitsanzo.

Ntchito zina za N, N' -methylene diacrylamide
N, N'-methylene diacrylamide monga reagent mankhwala ali osiyanasiyana ntchito, ndi oilfield fracturing madzimadzi, superabsorbent utomoni, madzi kutsekereza wothandizira, konkire zina, mowa sungunuka achigololo kuwala nayiloni utomoni, madzi mankhwala flocculant kaphatikizidwe zofunika zowonjezera, Ndiwothandizanso bwino mayamwidwe amadzi komanso posungira madzi, omwe amagwiritsidwa ntchito popanga utomoni wapamwamba kwambiri komanso kukonza nthaka, Amagwiritsidwanso ntchito kujambula, kusindikiza, kupanga mbale, ndi zina zambiri.
