Daim ntawv thov

1. Acts DAB CAS 91-95-2 ua ib qho tseem ceeb reagent rau kev soj ntsuam peroxidase kev ua hauv immunohistochemistry thiab western blotting thwmsim.

2. Ua haujlwm 3 3'-Diaminobenzidine ua monomer rau kev sib txuas siab -kev ua tau zoo polyimide thiab polybenzoxazole polymers nrog zoo thermal stability.

3. Siv nyob rau hauv manufacturing conductive polymers thiab tshwj xeeb dyes rau hluav taws xob thiab optoelectronic ntaus ntawv daim ntaub ntawv.

Cia thiab ceev faj

3 3'-Diaminobenzidine should be stored in a tightly sealed, light-resistant container at 10–25℃, in a cool, dry and well-ventilated area away from direct sunlight and heat sources. Nws yog nquag oxidation thiab discoloration thaum raug huab cua thiab lub teeb, yog li khaws DAB CAS 91-95-2 cais los ntawm oxidizing agents, acids, alkalis thiab av ib puag ncig los tiv thaiv kev degradation zoo.

Thaum tuav, hnav cov tshuaj lom neeg-cov hnab looj tes tiv thaiv, tsom iav thiab lub tsho tiv thaiv, thiab ua haujlwm hauv lub hood kom tsis txhob nqus plua plav thiab qhov muag / qhov muag. Tshem lub thawv tam sim tom qab siv. Kev pov tseg pov tseg nruj me ntsis raws li cov cai tswj kev phom sij hauv zos.

Dab tsi yog qhov txiaj ntsig ntawm kev noj 3 3'-Diaminobenzidine?

3 3'-Diaminobenzidine yog ib qho reagent tseem ceeb hauv kev tshawb fawb lom neeg thiab kev kho mob, ua rau muaj kev cuam tshuam txog kev ua haujlwm ntawm peroxidase hauv cov tswv yim xws li immunohistochemistry thiab western blotting, uas txhawb cov kab mob -txoj kev tshawb fawb thiab kev txhim kho kev kuaj mob. Tsis tas li ntawd, DAB CAS 91-95-2 ua raws li monomer rau kev sib txuas ua haujlwm siab polymers nrog tshwj xeeb thermal thiab mechanical zog, siv hauv aerospace thiab hluav taws xob khoom tsim khoom.
