General DNA/RNA Kab

Cov khoom siv no siv cov centrifugal adsorption kem uas tuaj yeem khi DNA thiab cov kab ke tshwj xeeb kom rho tawm cov genomic DNA hauv tag nrho cov ntshav kuaj. Lub centrifugal adsorption kem muaj cov yam ntxwv ntawm kev ua tau zoo thiab tshwj xeeb adsorption ntawm DNA, thiab tuaj yeem tshem tawm impurity proteins thiab lwm cov organic tebchaw hauv hlwb. Thaum cov qauv sib xyaw nrog cov lysis tsis muaj zog, cov protein muaj zog denaturant muaj nyob rau hauv lysis tsis tuaj yeem yaj cov protein sai sai thiab cuam tshuam cov nucleic acid. Cov kab adsorption adsorbs DNA hauv cov qauv raws li qhov tshwj xeeb ntsev ion concentration thiab pH tus nqi, thiab siv cov yam ntxwv ntawm cov adsorption kem cais thiab purify nucleic acid DNA los ntawm tag nrho cov ntshav coj mus kuaj, thiab siab purity nucleic acid DNA tau tuaj yeem ua tau raws li cov kev xav tau tom ntej.
