3,3′-Diaminobenzidine CAS:91-95-2

Ko te 3,3′-Diaminobenzidine (DAB) he matū e whakamahia whānuitia ana i roto i te matū koiora me te histology hei whakakoi i ngā pūmua, ngā waikawa karihi, me ētahi atu macromolecules. Ina waikurahia, ka puta he matū parauri ka taea te tiro ngāwari i raro i te karuārai. He maha ngā wā ka whakamahia te whakakoi DAB hei kite i te aroaro me te wāhi o ngā ngota motuhake, pērā i ngā antigens, ngā whākōkī rānei, i roto i ngā pūtau me ngā kiko. He whiringa rongonui mō ngā tikanga immunohistochemistry me te immunocytochemistry nā tōna tairongo me te pumau. Ka taea e te whakakoi DAB te tuku māramatanga nui ki ngā hanganga pūtau me ngā taunekeneke ngota, hei āwhina i te rangahau me te tātaritanga i roto i ngā mara pēnei i te rongoā, te koiora, me te pathology.

Te Whakamahinga me te Pānga

Te Matū Ārai Mate: He whānuitia te whakamahinga o te tae DAB i roto i te IHC hei kimi me te kimi i ngā pūmua, i ngā antigen rānei motuhake i roto i ngā wāhanga kiko. Mā tēnei tikanga ka āwhina ngā kairangahau me ngā tohunga mate ki te ako i te āhua o te pūtau, te tautuhi i ngā wāhanga pūtau, te tirotiro i ngā tauira whakaaturanga pūmua, me te tirotiro i ngā huringa e pā ana ki te mate. Ka taea te whakamahi i te tae DAB i roto i ngā mara pēnei i te rangahau mate pukupuku, te pūtaiao roro, te pathology, me te koiora whanaketanga.

Te matū ārai mate: Ka whakamahia hoki te tae DAB i roto i te ICC hei tiro i ngā ngota whainga i roto i ngā pūtau whakatipu. He rite tēnei tikanga ki te IHC, e āhei ai ngā kairangahau ki te tirotiro i te whakaaturanga pūmua, te wāhi noho, me ngā whanaketanga pūtau i roto i te vitro.

Te whakapūtanga in situ: Ka taea te whakamahi i te tae DAB hei kimi i ngā raupapa DNA, RNA rānei motuhake mā te whakamahi i ngā tikanga whakapūtanga in situ. Mā te whakakotahi i te tae DAB me ngā ine e aro ana ki ngā raupapa waikawa karihi tāpiri, ka taea e ngā kairangahau te whakaatu i te tauwāhi me te whakaaturanga o ngā ira i roto i ngā pūtau, i ngā kiko rānei.

Te karuārai irahiko: Ka taea te whakamahi i te tae DAB i roto i te karuārai irahiko hei tapanga i ngā hanganga motuhake, i ngā ngota rānei e hiahiatia ana. Ina honoa ki te tae muri-whakairoiro i te konganuku taumaha, ka taea e te tae DAB te whakarei ake i te rerekētanga me te tirohanga o ngā wāhanga pūtau i roto i ngā rangahau hanganga-rahi.
