Kev txhais ntawm acetocarmine .: saturated tov ntawm carmine nyob rau hauv 45 feem pua acetic acid siv tshwj xeeb tshaj yog rau cov sai staining ntawm tshiab unfixed chromosomes.
Kuj paub, vim li cas Acetocarmine siv hauv mitosis?
Stains yog siv hauv kev tshawb fawb microscopic txhawm rau txhim kho qhov sib txawv ntawm cov khoom siv lom neeg tshwj xeeb hauv cov qauv. Acetocarmine yog li stain siv kom stain nucleic acid hauv cov hlwb. Raws li acetocarmine tshwj xeeb-stain chromosomes sib nrug ntawm cytoplasm, nws tuaj yeem ua tau siv kom pom cov chromosomes hauv mitotic kev kawm.
Tom qab, lo lus nug yog, Dab tsi yog xim ntawm Acetocarmine? Safranin hmoov - 1 g Distilled dej - 100 ml Nws yog ib tug hluavtaws dye uas muab liab los yog liab. xim rau qhov khoom stained. 3. Acetocarmine : Nws yog tsuas yog siv los stain chromosomes hauv kev kawm ntawm cov hlwb.
Tsis tas li ntawd, Acetocarmine stain siv rau dab tsi?
Arvind Singh. Banaras Hindu University. Acetocarmine yog ib qho tsis tshwj xeeb nuclear stain uas tsuas khi cov chromosomes thiab muab xim rau lawv. Txawm li cas los xij, tshwj xeeb nuclear stain (piv txwv li feulgen) reacts nrog chromosomes muab xim rau lawv. Acetocarmine yog ib tug dye tau los ntawm kab.
Yuav ua li cas ua Acetocarmine?
Acetocarmine Kev npaj (1% tov) Dissolve 10 g carmine (Fisher C579-25) nyob rau hauv 1 L ntawm 45% glacial acetic acid, ntxiv boileezers, thiab reflux rau 24 teev. Lim rau hauv cov fwj tsaus thiab khaws cia ntawm 4 ° C. Cov tshuaj no tuaj yeem khaws cia rau lub sijhawm ntev.

Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
