Khoom: 3,3',5,5'-Tetramethylbenzidine yog dawb crystalline hmoov, odorless, tasteless, insoluble nyob rau hauv dej, yooj yim soluble nyob rau hauv acetone, ether, dimethyl sulfoxide, dimethylformamide, thiab lwm yam Organic solvents.
Kev npaj: 3,3,5,5-Tetramethylbenzidine yog ib qho tseem ceeb chromogen reagent.Siv 2,6-dimethylaniline ua raw khoom, los ntawm kev ua kom muaj zog, oxidative coupling thiab purification, ntshiab 3,3,5,5-tetramethylbenzidine yog tau, thiab tag nrho cov tawm los mus txog 65%.
Kev ua yeeb yam lom neeg: TMB (BMblue) yog chromogenic substrate rau immunohistochemistry thiab ELISA.
Kev Siv: Cov khoom no yog cov khoom siv tsis zoo rau benzidine 1 (Ames kuaj tsis zoo), haum rau peroxidase substrate rau enzyme-linked immunosorbent assay.Lub substrate yields ib tug soluble bluish kawg khoom uas yuav nyeem tau spectrophotometrically ntawm 370 los yog 620-650 nm.TMB cov tshuaj tiv thaiv tuaj yeem nres nrog 2MH2SO4 (dhau daj) thiab nyeem ntawm 50 nm ntawm 4Chemicalbook.Ib qho rhiab thiab tshwj xeeb reagent rau kev kuaj ntshav, ntsuas hemoglobin, thiab ntsuas peroxidase.
Siv: Ib qho tshiab thiab nyab xeeb chromogen reagent;TMB tau maj mam hloov cov muaj zog carcinogen benzidine thiab lwm yam carcinogenic benzidine derivatives, thiab yog siv nyob rau hauv kev soj ntsuam kuaj, forensic xeem, kev ua txhaum cai thiab soj ntsuam ib puag ncig thiab lwm yam teb;tshwj xeeb tshaj yog nyob rau hauv kev soj ntsuam biochemical kuaj, TMB, raws li ib tug tshiab substrate rau peroxidase, tau dav siv nyob rau hauv enzyme immunoassay (EIA) thiab enzyme-txuas immunosorbent assay (ELISA);Nws yog tsuas yog siv rau hauv cov haujlwm hauv qab no: occult ntshav ntiv tes kuaj pom;Kev tshawb pom sai ntawm cawv hauv cov qaub ncaug;kev npaj ntawm cov zis kuaj strips;kuaj pom tus kab mob siab;kuaj kuaj cev xeeb tub;kev txiav txim siab sai ntawm cov piam thaj, hemoglobin, albumin hauv cov ntshav thiab zis;fecal occult kuaj ntshav;Kev txiav txim siab ntawm granulocyte tus nqi hauv cov ntshav, steroids, Kev kuaj xyuas cov tshuaj hormones kev sib deev;kev txiav txim siab ntawm kev ua haujlwm enzymatic;nrhiav kom tau cov antigens, cov tshuaj tiv thaiv kab mob thiab cov khoom siv caj ces
