Kab DNA/RNA dav dav

Cov khoom siv no siv lub centrifugal adsorption kem uas tuaj yeem khi DNA thiab lub kaw lus buffer tshwj xeeb los rho tawm genomic DNA hauv cov qauv ntshav tag nrho. Lub centrifugal adsorption kem muaj cov yam ntxwv ntawm kev ua haujlwm zoo thiab tshwj xeeb adsorption ntawm DNA, thiab tuaj yeem tshem tawm cov protein impurity thiab lwm yam organic compounds hauv cell. Thaum cov qauv sib xyaw nrog lysis buffer, cov protein denaturant muaj zog uas muaj nyob hauv lysis buffer tuaj yeem yaj cov protein sai sai thiab dissociate cov nucleic acid. Lub adsorption kem adsorbs DNA hauv cov qauv nyob rau hauv qhov xwm txheej ntawm cov ntsev ion concentration thiab pH tus nqi, thiab siv cov yam ntxwv ntawm lub adsorption kem los cais thiab ntxuav cov nucleic acid DNA los ntawm cov qauv ntshav tag nrho, thiab cov nucleic acid DNA purity siab tau txais tuaj yeem ua tau raws li cov kev cai xeem tom ntej.
