He mea hoʻopili crosslinking no nā kumu N, N'-Methylenebisacrylamide

N,N' -methylene diacrylamide (MBAm a i ʻole MBAA)he mea hoʻohui crosslinking i hoʻohana ʻia i ka hoʻokumu ʻana i nā polymers e like me polyacrylamide. ʻO kona ʻano molekala C7H10N2O2, CAS: 110-26-9, nā waiwai: ka pauka crystalline keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol, acetone a me nā mea hoʻoheheʻe ʻē aʻe. ʻO ka Diacrylamide kahi hui o ka polyacrylamide gel (no SDS-PAGE) hiki ke hoʻohana ʻia i ka biochemistry. ʻO ka diacrylamide polymerizes meacrylamidea hiki iā ia ke hana i nā loulou ma waena o nā kaulahao polyacrylamide, no laila e hana i kahi pūnaewele polyacrylamide ma mua o ka laina laina ʻole.polyacrylamidekaulahao.

Agena hookui
Ma ke kemika a me ka biology, ʻo ka hoʻopaʻa ʻana he paʻa e hoʻopili ai i kekahi kaulahao polymer i kekahi. Hiki i kēia mau loulou ke ʻano o ka covalent a ionic bond, a ʻo ka polymer he synthetic a kūlohelohe paha (e laʻa me ka protein).
Ma ke kemika polymer, pili pinepine ka "crosslinking" i ka hoʻohana ʻana i ka crosslinking e paipai i nā loli i nā waiwai kino o ka polymer.
Ke hoʻohana ʻia ka "crosslinking" ma ke kahua o ka biology, pili ia i ka hoʻohana ʻana i nā probes e hoʻopili pū i nā protein e nānā i ka pilina protein-protein a me nā ʻano hana hoʻohui ʻē aʻe.
ʻOiai ua hoʻohana ʻia ka huaʻōlelo e pili ana i "ka hoʻopili ʻana i nā kaulahao polymer" ma nā ʻepekema ʻelua, ʻokoʻa ke ʻano o ka hoʻopili ʻana a me ke kikoʻī o ka mea hoʻopili crosslinking. E like me nā ʻepekema a pau, ua uhi ʻia, a ʻo ka wehewehe ʻana he wahi hoʻomaka no ka hoʻomaopopo ʻana i kēia mau nuances.

Polyacrylamidegel electrophoresis
ʻO ka Polyacrylamide gel electrophoresis (PAGE) kahi ʻenehana i hoʻohana nui ʻia i ka biochemistry, forensics, genetics, molecular biology, a me ka biotechnology no ka hoʻokaʻawale ʻana o nā macromolecules biological (maʻamau nā protein a i ʻole nucleic acid) e pili ana i kā lākou electrophoretic mobility. ʻO ka mobility electrophoretic kahi hana o ka lōʻihi molekala, conformation, a me ka uku. ʻO ka polyacrylamide gel electrophoresis kahi mea hana ikaika no ka nānā ʻana i nā laʻana RNA. Ke hoʻopaʻa ʻia ka gel polyacrylamide ma hope o ka electrophoresis, hāʻawi ia i ka ʻike e pili ana i ke ʻano o ka ʻano ʻano RNA.

Nā hoʻohana ʻē aʻe o N,N'-methylene diacrylamide
ʻO N, N '-methylene diacrylamide ma ke ʻano he reagent kemika he nui nā noi, ʻo ia ka ʻaila fracturing fluid, superabsorbent resin, wai blocking agent, concrete additives, alcohol soluble sexy light nylon resin, water treatment flocculant synthesis o kahi mea hoʻohui koʻikoʻi, he mea maikaʻi hoʻi ia i ka wai absorption agent a me ka wai hoʻomau i hoʻohana ʻia no ka hoʻomaikaʻi ʻana i ka lepo. kiʻi, paʻi ʻana, hana pā, etc.
