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
N, N '-methylene diacrylamide ma ke ʻano he reagent kemika he ʻano nui o 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 hoʻoheheʻe wai maikaʻi a me ka mea mālama wai, hoʻohana ʻia i ka hana ʻana i ka resin superabsorbent a me ka hoʻomaikaʻi ʻana i ka lepo, Hoʻohana pū ʻia no ke kiʻi, paʻi ʻana, hana pā, etc.
