3,3′,5,5′-Tetramethylbenzidine CAS:54827-17-7

Ku-biochemistry kanye ne-molecular biology, i-3,3', 5,5'-Tetramethylbenzidine isebenza njenge-reagent ebalulekile yokuthola nokulinganisa umsebenzi we-enzymatic, ikakhulukazi owe-peroxidases. Lapho i-TMB i-oxidated yi-peroxidase lapho kukhona i-hydrogen peroxide, kukhiqizwa umkhiqizo we-chromogenic oluhlaza okwesibhakabhaka, okuvumela ukubonakala kanye nokulinganisa ukusabela kwe-enzymatic. Lesi sici senza i-TMB ibe ithuluzi elibalulekile ekuhlolweni okuhlukahlukene kwe-immunoassay, kufaka phakathi i-ELISA, lapho ivame ukusetshenziswa khona ukuthola ukuba khona kwama-antigen athile noma ama-antibodies kumasampula e-biological. Ukufundwa kwe-colorimetric okunikezwe yi-TMB kuvumela abacwaningi kanye nochwepheshe bokuxilonga ukuthi bahlole ukuhlushwa kwama-molecule aqondiwe ngokunembile, okufaka isandla ekuqondeni izinqubo zesifo, ukutholakala kwe-biomarker, kanye nokuhlolwa kokuxilonga. Ngaphezu kwalokho, i-TMB ithola ukusetshenziswa ekuxilongweni kwemitholampilo, lapho impendulo yayo ye-colorimetric yenza kube lula ukuthola ama-biomarker, ama-agent athelelanayo, kanye nezici zokuzivikela komzimba. Ngokusebenzisa ikhono le-TMB lokukhiqiza ushintsho lombala olubonakalayo lapho kukhona abahlaziyi abathile kanye nomsebenzi we-peroxidase, ochwepheshe bezempilo bangenza izivivinyo ezisheshayo nezibucayi zezimo ezahlukahlukene, kusukela ezifweni ezithelelanayo kuya ezimpawini zomdlavuza. Ukuguquguquka kwe-TMB ekuhlolweni kwezokwelapha kusekela ukuthuthukiswa kwamathuluzi okuxilonga kanye namapulatifomu asetshenziswa emalabhorethri ezokwelapha, ezindaweni zokunakekelwa, kanye nasezikhungweni zocwaningo. Ngaphezu kwalokho, i-TMB isetshenziswa ocwaningweni lwe-biotechnology kanye nemithi ukuze kuhlaziywe inani kanye nekhwalithi yokusebenzisana kwamaprotheni namaphrotheni, i-kinetics ye-enzyme, kanye nokutholakala kwemithi. Ukuhambisana kwayo nezinhlelo ezenzakalelayo kanye nabafundi be-microplate kuvumela ukuhlolwa okuphezulu kanye nokuhlaziywa, okwenza kube lula ukutadisha izindlela ze-biochemical, ukusebenzisana kwe-receptor-ligand, kanye nokuhlolwa kwamakhemikhali okwelapha. Ukusetshenziswa kwe-TMB kudlulela ekuhlolweni kokuvinjelwa kwe-enzyme kanye nokuhlukaniswa kwamaprotheni ahlanganisiwe, okufaka isandla ekuthuthukisweni kwemithi kanye nokuqonda izindlela zama-molecule ezibangela izifo. Ekuphetheni, i-3,3', 5,5'-Tetramethylbenzidine idlala indima ebalulekile ocwaningweni lwe-biochemical kanye ne-biomedical, isebenza njengesisekelo esiguquguqukayo nesibucayi sokutholwa kwemibala ekuhlolweni kwe-immunoassays, i-ELISA, ukuxilongwa kwemitholampilo, kanye nokutholakala kwemithi. Amandla ayo okukhiqiza ushintsho lombala oluzinzile nolubonakalayo lapho kukhona umsebenzi we-peroxidase enza kube nokulinganisa okunembile nokuphumelelayo kokuxhumana kwe-biomolecular, imisebenzi ye-enzyme, kanye nezimpawu ezihlobene nezifo. Ukusetshenziswa kabanzi kwe-TMB kugcizelela ukubaluleka kwayo ekuthuthukiseni ucwaningo lwesayensi nolwezokwelapha, okufaka isandla ekuthuthukisweni kobuchwepheshe bokuxilonga, ukungenelela kokwelapha, kanye nokuqonda kwethu izinqubo eziyinkimbinkimbi zezinto eziphilayo. Ukuhlola okuqhubekayo kanye nokwenza ngcono ukuhlolwa okusekelwe ku-TMB cishe kuzoholela ekuthuthukisweni okwengeziwe kanye nokuthuthuka ocwaningweni lwezokwelapha kanye nokuxilongwa kwemitholampilo.
