Te pūromāita Etidium CAS:1239-45-8 Utu Kaihanga

E whakamahia whānuitia ana te ethidium bromide hei tae waikawa karihi i roto i ngā rangahau koiora ngota. Ka whakamahia hei whakaatu i te DNA me te RNA i roto i ngā tikanga pēnei i te electrophoresis gel. Ina tāpirihia ki tētahi tauira DNA, RNA rānei, ka uru te ethidium bromide ki waenganui i ngā takirua turanga o ngā waikawa karihi, ka taea ai te whakaatu i a rātou i raro i te mārama ultraviolet hei roopu fluorescent. Mā tēnei tikanga tae ka āwhina ngā kairangahau ki te tātari me te tautuhi i ngā kongakonga DNA me te RNA i roto i tētahi tauira.
