Eosin Y yog xanthene xim thiab yog siv rau qhov sib txawv staining ntawm connective cov ntaub so ntswg thiab cytoplasm. Nyob rau hauv histopathology, nws yog siv raws li ib tug counterstain tom qab hematoxylin thiab ua ntej methylene xiav. Nws kuj yog siv li abackground stain, yog li muab qhov sib piv rau cov nuclear stains.
Ib yam li ntawd, koj tuaj yeem nug, eosin stain siv rau dab tsi?
Siv hauv histology Eosin yog feem ntau siv Raws li kev tawm tsam rau hematoxylin hauv H&E (haematoxylin thiab eosin ua ) staining . H&E staining yog ib qho ntawm feem ntau siv cov txheej txheem hauv histology. Cov ntaub so ntswg ua qias neeg nrog hematoxylin thiab eosin ua qhia cytoplasm ua qias neeg liab-txiv kab ntxwv thiab nuclei ua qias neeg tsaus, xiav lossis ntshav.
Ib sab saum toj no, histological staining yog dab tsi thiab vim li cas nws thiaj siv? Kev pleev xim yog siv los qhia txog cov yam ntxwv tseem ceeb ntawm cov ntaub so ntswg thiab txhim kho cov ntaub so ntswg sib piv. Hematoxylin yog ib qho yooj yim dye uas feem ntau siv hauv qhov txheej txheem no thiab stains lub nuclei muab nws cov xim xiav thaumeosin (lwm yam stain xim siv hauv histology ) stains lub cell lub nucleus muab nws ib tug pinkish stain.
Kuj nug, Xim ntawm eosin yog dab tsi?
liab
Cov ntaub so ntswg twg stained los ntawm eosin?
Eosin yog feem ntau dye rau stain thecytoplasm hauv histology. Nws yog ib qho acidic dye uas khi rau cov khoom tseem ceeb ntawm lub cell, feem ntau yog cov proteins nyob hauv cytoplasm. Nws muab cov xim liab liab uas sib txawv ntawm cov xim xiav tsaus nti nuclearhematoxylin staining (Fig. 1.3B).

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
