N, N'-methylene diacrylamide (MBAm lossis MBAA)yog ib tug crosslinking tus neeg sawv cev siv nyob rau hauv tsim ntawm polymers xws li polyacrylamide. Nws cov mis molecular yog C7H10N2O2, CAS: 110-26-9, cov khoom: dawb crystalline hmoov, soluble hauv dej, kuj soluble hauv ethanol, acetone thiab lwm yam organic solvents. Diacrylamide yog ib qho chaw ntawm polyacrylamide gel (rau SDS-PAGE) uas tuaj yeem siv rau hauv biochemistry. Diacrylamide polymerizes nrogacrylamidethiab muaj peev xwm tsim cov kab sib txuas ntawm cov saw hlau polyacrylamide, yog li tsim ib lub network polyacrylamide es tsis yog cov kab sib txuas.polyacrylamidechains.
Crosslinking tus neeg sawv cev
Nyob rau hauv chemistry thiab biology, crosslinking yog ib daim ntawv cog lus uas txuas ib tug polymer saw mus rau lwm tus. Cov kev sib txuas no tuaj yeem siv los ntawm covalent lossis ionic bonds, thiab cov polymer yuav yog hluavtaws lossis ntuj (xws li cov protein).
Hauv polymer chemistry, "crosslinking" feem ntau yog hais txog kev siv crosslinking los txhawb kev hloov pauv hauv lub cev ntawm cov khoom siv polymer.
Thaum "crosslinking" yog siv nyob rau hauv biology, nws hais txog kev siv cov kev sojntsuam los txuas cov proteins ua ke los tshuaj xyuas cov protein-protein kev sib cuam tshuam thiab lwm yam kev sib txuas tshiab.
Txawm hais tias lo lus siv los xa mus rau "kev sib txuas ntawm cov saw hlau polymer" hauv ob qho tib si kev tshawb fawb, qib ntawm kev sib txuas thiab qhov tshwj xeeb ntawm tus neeg sawv cev crosslinking sib txawv. Raws li nrog rau tag nrho cov kev tshawb fawb, muaj sib tshooj, thiab cov lus piav qhia hauv qab no yog qhov pib rau kev nkag siab cov nuances no.
Polyacrylamidegel electrophoresis
Polyacrylamide gel electrophoresis (PAGE) yog cov txheej txheem dav siv hauv biochemistry, forensics, genetics, molecular biology, thiab biotechnology rau kev sib cais ntawm cov macromolecules lom (feem ntau yog cov proteins lossis nucleic acids) raws li lawv cov electrophoretic mobility. Electrophoretic mobility yog kev ua haujlwm ntawm molecular ntev, conformation, thiab nqi. Polyacrylamide gel electrophoresis yog cov cuab yeej muaj zog rau kev tshuaj xyuas RNA cov qauv. Thaum cov polyacrylamide gel yog denatured tom qab electrophoresis, nws muab cov ntaub ntawv hais txog cov muaj pes tsawg leeg ntawm RNA hom qauv.
Lwm yam kev siv ntawm N, N '-methylene diacrylamide
N, N '-methylene diacrylamide ua cov tshuaj reagent muaj ntau yam kev siv, nws yog oilfield fracturing kua, superabsorbent resin, dej thaiv tus neeg saib xyuas, qhob additives, cawv soluble sexy lub teeb nylon resin, dej kho flocculant synthesis ntawm ib qho tseem ceeb additive, nws kuj yog ib tug zoo dej nqus tus neeg saib xyuas thiab dej tuav tus neeg saib xyuas, siv nyob rau hauv kev tsim cov superabsorbent resin thiab av txhim kho, Kuj tseem siv rau kev thaij duab, luam ntawv, phaj ua, thiab lwm yam.
