Waikawa Diethylene triamine pentaacetic CAS:67-43-6 Whakaahua Matua

Waikawa pentaacetic diethylene triamine CAS: 67-43-6

Ko te waikawa Diethylene triamine pentaacetic (DTPA) he matū e whakamahia whānuitia ana hei kaiāwhina chelating. He kaha tōna ki te here ki ngā katote konganuku taumaha, inā koa ko ērā pēnei i te mata, te mercury, me te cadmium, hei hanga i ngā matatini pumau. E whakamahia ana te DTPA i roto i ngā momo tono, tae atu ki te whakaora taiao, ngā maimoatanga hauora, ngā tukanga ahumahi, me ngā radiopharmaceuticals. Nā ōna āhuatanga chelating konganuku ka whai hua ki te tango i ngā konganuku taumaha mai i te wai para, ki te rongoā i te paitini konganuku taumaha, ki te aukati i te pokanoa ki ngā tauhohenga matū, me te whakahaere i te tukunga whai take o ngā rongoā whakaora. I te nuinga, he matū maha ngā whakamahinga o te DTPA me ngā tono nui i roto i ngā momo ahumahi.

Te Whakamahinga me te Pānga

Te Whakakore i ngā RNase: Ko te kaupapa matua o te DEPC he whakakore i ngā RNase, arā, ngā whākōkī ka taea te whakaiti i te RNA. Ka tauhohe te DEPC ki ngā toenga histidine i roto i ngā RNase, ka whakarerekē i ō rātou pae hohe, ā, ka kore e mahi. Mā tēnei ka mau tonu te pono o te RNA i ngā whakamātautau pēnei i te wehenga RNA, te tuhi whakamuri, me te raupapatanga RNA.

Te tiaki i ngā tauira RNA: He maha ngā wā ka whakamahia te maimoatanga DEPC ki ngā taputapu taiwhanga, pērā i ngā ngongo microcentrifuge, ngā pito pipette, me te wai e whakamahia ana i roto i ngā whakamātautau RNA. Ka āwhina tēnei ki te aukati i ngā RNases toenga kei reira pea, me te ārai i te pirau o te RNA i te wā e whakahaeretia ana, e rongoatia ana hoki te tauira.

Te whakarite matū kore-RNAse: Ka taea te whakamahi i te DEPC hei rongoā i ngā otinga, i ngā matū rānei e hiahia ana kia kore-RNAse, pērā i ngā pūhui, ngā otinga Tris-EDTA (TE), te wai rānei e whakamahia ana i roto i ngā whakamātautau koiora ngota. Kātahi ka taea te whakamahi haumaru i ēnei otinga kua rongoāhia hei whakaiti i te pirau o te RNA.

Te whakarerekētanga DNA: Ka taea hoki e te DEPC te tauhohe ki ngā rōpū amino i roto i ngā ngota DNA, ka hua ake te whakarerekētanga carbethoxylated o ngā turanga DNA. Ka taea te whakamahi i tēnei i roto i ngā tono motuhake, pērā i ngā tauhohenga raupapatanga DNA, te whakarerekētanga DNA rānei mō ngā rangahau hononga whakawhiti.
