Cov xim cuav, piv txwv li aniline dyes lossis thee tar dyes, tau siv dav ua ntau hom. Nws qhov tsis zoo yog tias nws yooj yim faded los ntawm tshav ntuj, anphthia xiav, ci ntsuab, methyl ntsuab thiab zoo li yooj yim dua faded. Kev tsim tawm ntawm kev saib xyuas rau master acidity, thiab zam qhov ncaj qha hnub ci, tab sis kuj tom qab ob peb xyoos tsis thim.
Acid Magenta
Acid magenta yog tshuaj pleev xim acid, liab hmoov, tuaj yeem tiv taus dej, dej hauv lub cawv me ntsis (0.3%). Cov nrws yas yog cov xovtooj ntawm cov cell ua zoo, tau siv dav hauv tsiaj tsim, siv rau hauv cov nroj tsuag rau kev zas rau cov nyias nyias phab ntsa xws li cortex, myelin thiab cellulose phab ntsa. Nws kis nrog methyl ntsuab thiab tuaj yeem qhia mitochondria.
Cov ntaub so ntswg yog tsau rau hauv cov kua qaub ua ntej zas, uas ua rau nws muaj zog dyeing. Acid magenta nyhav ua haujlwm nrog alkali, yog li dhau ntawm qhov uas tub qaug thiab nyhav rau cov kais dej.
Congo Liab
Congo liab yog cov tshuaj pleev kua qaub, liab hmoov-zoo li, soluble hauv dej haus cawv, kua qaub yog xiav. Nws tuaj yeem ua cov xim daig thiab kuj ua qhov taw qhia. Nws feem ntau ua raws li kev ntxaws rafter rau sumalor lossis lwm cov xovtooj ntawm tes rau hauv cov khoom cog. Thaum nws dyes cytoplasm, nws tuaj yeem zas kua nplaum lossis cellulose liab. Hauv cov tsiaj cov nqaij ua kom zoo siv los zas rau cov plaub hau neural, cov ntaub so ntswg, cov ntaub ntawv embryonic, thiab lwm yam. Kev kho lub cev kom qhuav sai.
Methyl Xiav
Methyl xiav yog lub cev tsis muaj zog acidic uas yaj hauv dej thiab cawv. Methyl xiav yog siv dav hauv cov thev naus laus zis ntawm cov tsiaj thiab nroj tsuag. Nws thiab Yihong tuaj yeem zas qia cov hlab ntsha, kuj yog qhov tseem ceeb uas tsis pom kev hauv cov khoom tsim kab mob. Nws cov kua aqueous yog cov nyob dyes hauv protozoa. Methyl xiav yog oxidized heev thiab yog li ntawd tsis tuaj yeem khaws cia ntev tom qab zas nws.
Khoom ntsuab
Cov xim ntsuab yog cov kua pleev kua qaub uas ua rau hauv dej (4% solubility) thiab dej cawv (9% solubility). Cov xim ntsuab yog cov tshuaj pleev rau lub ntsej muag uas tso cov xaim cell cell hauv cov cellulose uas muaj cov slurry thiab yog siv dav hauv cov xov tooj dyed thiab cog cov ntaub so ntswg. Nws thiab Sumu, panyu thiab teev raws li peb qhov feem ntau siv tshuaj pleev xim rau hauv cov nroj tsuag histological seducron.
