Ultracentrifuges yog laboratory centrifuges nrog rotors uas tig ntawm qhov nrawm heev, feem ntau yog li ntawm 60, 000 RPM thiab 200, 000 x g txog 150, 000 RPM thiab 1, 000, 000 x g. … Preparative ultracentrifuges cais los yog pellet biological hais, kab mob, organelles, daim nyias nyias thiab biomolecules xws li DNA, RNA thiab lipoproteins.
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.
Ultracentrifuge siv rau dab tsi?
Ultracentrifuge applications
Ultracentrifuges feem ntau yog siv hauv molecular biology, biochemistry, thiab cell biology. Kev siv ntawm ultracentrifuges suav nrog kev sib cais ntawm cov khoom me me xws li cov kab mob, cov kab mob kis, cov protein thiab / lossis cov protein complexes, lipoproteins, RNA, thiab plasmid DNA.
Ultracentrifuge txoj cai yog dab tsi?
Txoj cai ntawm Ultracentrifuge
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 tus qauv. Cov molecules loj dua txav ceev, qhov me me molecules txavqeeb qeeb.
