Nyob rau hauv qhov ceev gradient centrifugation txheej txheem zoo ib yam. … Cov kiv cua los ntawm lub centrifuge ua rau cov khoom ntom ntom ntau txav mus rau sab nraud Cov khoom no muaj ntau dua thiab nqa mus ntxiv los ntawm lawv qhov inertia. Tsawg cov khoom me me ces nyob ntawm qhov chaw ntawm tus qauv.
Lub hauv paus ntsiab lus ntawm qhov ntom ntom centrifugation yog dab tsi?
Density gradient centrifugation tau tshaj tawm tias yog ib qho cuab yeej rau kev sib cais ntawm cov kab mob los ntawm cov khoom noj matrices. Lub hauv paus ntsiab lus yog ua raws li ib qho kev txo qis ntawm kev ncua kev daws teeb meem thiab kev tsiv teb tsaws ntawm lub hom phiaj mus rau qhov sib npaug ntawm cov qauv raj thaum lub sij hawm centrifugation
Dab tsi yog qhov ceev gradient centrifuge?
fig. 1.3. Ntws Gradient Centrifugation, nyob rau hauv nws daim ntawv qub thiab yooj yim tshaj plaws, yog hwj tseb nce los ntawm sab saum toj mus rau hauv qab(a). Nyob rau hauv luv luv los yog qeeb centrifugation loj hais sediment sai dua li me me hais (B).
Dab tsi yog siv qhov ceev gradient centrifugation?
Density gradient centrifugation enables cov kws tshawb fawb cais cov tshuaj raws li qhov loj me, cov duab, thiab qhov ntom ntomMeselson thiab Stahl tau tsim ib hom kev ceev gradient centrifugation, hu ua isopycnic centrifugation uas siv cov tshuaj. ntawm cesium chloride los cais DNA molecules raws li qhov ceev ib leeg.
Vim li cas qhov ceev gradient centrifugation zoo dua?
Centrifugal quab yuam cais cov khoom tsis yog raws li qhov ceev, tab sis kuj ntawm qhov loj me thiab cov duab. Nyob rau hauv sib piv, ib tug tshwj xeeb equilibrium density-gradient centrifugation ua ib tug sib cais profile nyob ntawm seb particle-density ib leeg, thiab yog li tsim nyog rau ntau fine-grained sib cais.
