Lub ultracentrifuge ua haujlwm ntawm tib lub hauv paus ntsiab lus raws li tag nrho lwm cov centrifuges. … Nyob rau hauv ib qho ultracentrifuge, tus qauv yog tig ntawm ib qho axis, ua rau lub zog perpendicular, hu ua centrifugal force, uas ua rau cov khoom sib txawv ntawm cov qauv. Cov molecules loj dua txav nrawm dua, qhov me me molecules txav qeeb dua.
Lub centrifuge ua haujlwm yooj yim li cas?
A centrifuge yog ib qho khoom siv, feem ntau tsav los ntawm lub tshuab hluav taws xob, uas tso ib qho khoom, piv txwv li, lub rotor, nyob rau hauv ib qho kev sib hloov nyob ib ncig ntawm lub axis ruaj. Lub centrifuge ua haujlwm los ntawm siv lub hauv paus ntsiab lus ntawm sedimentation: Raws li kev cuam tshuam ntawm lub zog gravitational (g-force), cov khoom sib cais raws li lawv qhov ntom.
Lub hauv paus ntsiab lus ntawm ultracentrifugation yog dab tsi?
Lub hauv paus ntawm ultracentrifugation yog tib yam li ib txwm centrifugation: cais cov khoom ntawm cov tshuaj raws li lawv qhov loj thiab qhov ntom ntom, thiab qhov ntom ntom (viscosity) ntawm nruab nrab (hloov) (Ohlendieck & Harding, 2017).
Qhov txawv ntawm ultracentrifuge thiab centrifuge yog dab tsi?
yog tias ultracentrifuge yog high-speed centrifuge, tshwj xeeb tshaj yog ib qho dawb los ntawm convection uas yog siv los cais cov colloidal hais thaum centrifuge yog ib qho khoom siv uas sib xyaw ntawm denser thiab sib dua. cov ntaub ntawv (ib txwm dispersed nyob rau hauv ib tug kua) yog sib cais los ntawm kev spun ntawm lub hauv paus axis ntawm kev kub ceev.
Vim li cas centrifugation ua tiav?
Centrifugation yog siv los sau cov hlwb, txhawm rau txhawm rau DNA, ua kom huv cov kab mob, thiab paub qhov txawv me ntsis ntawm qhov sib txawv ntawm cov molecules. Feem ntau lub chaw soj nstuam ua haujlwm tshawb fawb yuav muaj ntau tshaj ib hom centrifuge, txhua tus muaj peev xwm siv ntau yam rotors.
