N,N' -methylene diacrylamide (MBAm, MBAA ranei)he kaihoko whakawhiti i whakamahia i roto i te hanganga o nga polymers penei i te polyacrylamide. Ko tana tauira ngota ko C7H10N2O2, CAS: 110-26-9, nga taonga: te paura tioata ma, ka whakarewahia ki te wai, ka whakarewahia ano ki te waihano, acetone me etahi atu whakarewa pararopi. Ko te Diacrylamide he puhui o te polyacrylamide gel (mo SDS-PAGE) ka taea te whakamahi i roto i te koiora. Diacrylamide polymerizes kiacrylamidea ka taea e ia te hanga hononga-whakawhitinga i waenga i nga mekameka polyacrylamide, na reira ka hanga he whatunga polyacrylamide kaua ki te raina kore hono.polyacrylamidemekameka.
He kaihoko hono
I roto i te matū me te koiora, ko te hononga whakawhiti he here e hono ana i tetahi mekameka waerau ki tetahi atu. Ko enei hononga he ahua o te here katote, katote ranei, a he mea waihanga, he mea maori ranei te polymer (hei tauira, te pūmua).
I roto i te matū polymer, ko te tikanga "whakawhitiwhiti" e tohu ana ki te whakamahi i te hononga whakawhiti hei whakatairanga i nga huringa o nga ahuatanga o te tinana o te polymer.
Ina whakamahia te "whakawhitiwhiti" i roto i te mara o te koiora, e pa ana ki te whakamahi i nga rangahau hei hono i nga pūmua ki te tirotiro i nga taunekeneke pūmua-pūmua me etahi atu tikanga honohono hou.
Ahakoa e whakamahia ana te kupu ki te "hononga o nga mekameka polymer" i roto i nga mahi putaiao e rua, he rereke te tohu o te hononga whakawhiti me te motuhake o te kaihoko hono. Pērā ki ngā pūtaiao katoa, he inaki, ā, ko te whakamārama e whai ake nei he timatanga mo te maarama ki enei ahuatanga.
Polyacrylamidete hiko hiko
Ko te Polyacrylamide gel electrophoresis (PAGE) he tikanga e whakamahia nuitia ana i roto i te matū-koiora, te matapae, te ira, te koiora rapoi, me te hangarau koiora mo te wehenga o nga macromolecules koiora (te nuinga o nga pūmua, waikawa nucleic ranei) i runga i o raatau hikoi hiko. Ko te nekeneke hiko he mahi o te roa o te ngota, te hangahanga, me te utu. Ko te polyacrylamide gel electrophoresis he taputapu kaha mo te tarai i nga tauira RNA. I te wa e whakahekehia ana te kiri polyacrylamide i muri i te electrophoresis, ka tukuna he korero mo te hanganga o te tauira momo RNA.
Ko etahi atu whakamahinga o te N,N' -methylene diacrylamide
N, N '-methylene diacrylamide hei reagent matū he maha nga momo tono, he wai pakaru hinu, he kapia superabsorbent, he kaihoko aukati wai, he taapiri raima, he waipiro te wairewa nairona marama, he maimoatanga wai whakahiato flocculant o tetahi taapiri nui, he pai hoki te kaikawe wai me te kaihoko pupuri wai, whakamahia i roto i te hanga o te kapia superabsorbent me te whakapai ake i te oneone, Ka whakamahia ano hoki mo te whakaahua, te tuhi, te hanga pereti, aha atu.
