Dansyl chloride los yog 5- (DimethylAmino) Naphthalene-1-SulfonYL chloride yog cov tshuaj lom neeg cov tshuaj tiv thaiv nrog cov thawj cov amino hauv aliphatic thiab arines amines los tsim cov xim xiav-lossis xiav-ntsuab – fluorescent sulfonamide ad ad. Nws kuj tuaj yeem ua kom muaj kev cuam tshuam nrog amines lwm yam. Dansyl chloride siv dav dav los hloov cov amino acids; tshwj xeeb, kev ua raws qib protein thiab tshuaj tsom amino acid. Nws kuj tseem siv tau los sau npe hydroxyl thiab carboxylic acid ua haujlwm pawg.

Dansyl chloride kuj tseem yog suav nrog DNSC. Zoo li no, ib qho zoo sib xws, dansyl amide paub zoo li DNSA. Dhau li, cov protein-DNSC conjugates rhiab rau lawv ib puag ncig. Qhov no, ua ke nrog lawv lub peev xwm los txais lub zog (xws li hauv fluorescence resonance hloov hluav taws xob) los ntawm cov amino acid tryptophan, tso cai rau cov txheej txheem cim npe no los siv hauv kev tshawb nrhiav cov protein folding thiab puab.

Lub fluorescence ntawm cov sulfonamide ad ad tuaj yeem txhim kho los ntawm kev ntxiv alpha-cyclodextrin. Dansyl chloride tsis ruaj khov nyob rau hauv dimethyl sulfoxide, uas yuav tsum tsis txhob siv los npaj cov kev daws teeb meem.Qhov qhov cuam tshuam coefficient ntawm dansyl derivatives yog qhov tseem ceeb rau kev ntsuas lawv cov kev xav hauv kev daws. Dansyl chloride yog ib qho yooj yim tshaj plaws sulfonamide derivatives, yog li nws feem ntau ua haujlwm pib ua haujlwm los ntawm kev tsim tawm ntawm lwm cov kev tsim txiaj. Cov kev sib txawv yav dhau los tej zaum yuav muaj cov co ua kom sib txawv heev, tab sis lwm tus, xws li dansyl amide, zoo ib yam li dansyl chloride nyob rau hauv kev nqus thiab fluorescence yam ntxwv. Tab sis txawm rau dansyl chloride, muaj ntau yam ntawm ncua kev co co txiaj qhov tseem ceeb uas tau tshaj tawm. Qee qhov muaj nuj nqis yog siv los kwv yees qhov kev vam meej hauv kev sim ua kom cov zas xim rau cov protein. Lwm yam txiaj ntsig yuav raug siv los txiav txim siab ib qho kev ntsuas ncaj qha ntawm kev daws teeb meem. Saib cov lus hauv qab no txog tej nqi tshwj xeeb thiab lawv siv.
