Tom qab ntawd, qhov nyiaj stain ua haujlwm li cas?
Nyiaj staining yog txoj kev rhiab tshaj plaws colorimetric rau kev kuaj tag nrho cov protein. Cov txheej txheem muaj xws li deposition ntawm metallic nyiaj mus rau saum npoo ntawm ib gel ntawm qhov chaw ntawm cov protein bands. Nyiaj ions (los ntawm nyiaj nitrate nyob rau hauv staining reagent) cuam tshuam thiab khi nrog qee cov protein ua haujlwm.
Ib sab saum toj no, cov xim dab tsi tuaj yeem siv rau staining protein bands tom qab electrophoresis? Coomassie
Hais txog qhov no, ua li cas koj khaws nyiaj stained gel?
Gels rov- ua qias neeg tom qab siv Nyiaj Tshem tawm ™ tsis pom qhov txo qis hauv band siv los yog nce hauv keeb kwm yav dhau. Khw Nyob rau hauv chav tsev kub (18 - 26 ° C). Stable 1 xyoo thaum khaws cia raws li pom zoo nyob rau hauv thawj ntim. Rau kev tshawb fawb siv xwb.
Giemsa stain siv rau dab tsi?
Nws txawv stains tib neeg thiab kab mob hlwb ntshav thiab liab liab feem. Nws tuaj yeem yog siv rau Kev kuaj mob histopathological ntawm malaria thiab qee qhov lwm yam spirochete thiab protozoan ntshav parasites. Giemsa stain yog ib tug classic ntshav zaj duab xis stain rau peripheral ntshav smears thiab cov pob txha pob txha.

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
Puas yog Silver ua hluav taws xob yog cov khoom siv tshuaj?
Nyiaj yog lustrous, mos, ductile heev thiab malleable hlau. Nws muaj qhov zoo tshaj plaws hluav taws xob conductivity ntawm tag nrho cov hlau, tab sis nws tsis yog dav siv rau hluav taws xob lub hom phiaj vim nws kim heev. Nyiaj tsis yog tshuaj lom neeg hlau; Txawm li cas los xij, nitric acid thiab kub concentrated sulfuric acid yuav ua rau nws
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Dab tsi yog qhov tseem ceeb tshaj plaws reagent nyob rau hauv txoj kev Gram stain?
Lub ntsiab stain ntawm Gram txoj kev yog siv lead ua violet. Crystal violet qee zaum hloov nrog methylene xiav, uas zoo sib xws. Cov kab mob uas khaws cia cov siv lead ua violet-iodine complex tshwm ntshav xim av nyob rau hauv kev tshuaj xyuas microscopic
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
