Macro & micro-xeem kis DNA / RNN

Cov khoom siv no tau txais cov ntawv tshaj tawm Centrifugion adsorption cov ntawv uas tuaj yeem khi cov DNA tshwj xeeb thiab ib qho tsis tau rho tawm cov ntshav tag nrho cov ntshav. Lub Centrifugion rau sab muaj cov yam ntxwv ntawm DNA uas muaj txiaj ntsig zoo thiab muaj peev xwm ua tau zoo tshem tawm cov protein thiab lwm cov organic sib xyaw ua ke hauv cov hlwb. Thaum cov qauv sib xyaw nrog cov lysis tsis muaj protein, cov protein muaj zog denaturant muaj cov protein sai sai tau sai sai cov protein thiab cais cov nucleic acid. Adsorption Kem Adsorbs DNA nyob rau hauv cov qauv nyob rau hauv cov xwm txheej ntawm cov yam ntxwv adsorption thiab ntxuav cov txiaj ntsig ntawm cov ntshav, thiab siv cov ntshav siab ntawm cov kua ntshav tag nrho, thiab lub siab purity nucleic acid DNA tau tuaj yeem ua tau raws li qhov yuav tsum tau ua tiav.
