Ikholamu ejikelezayo

Inkcazo emfutshane:

Ikholamu yokujikeleza izaliswe sisixa esikhulu seglasi yefayibha inwebu, esekwe kwindlela yokukhupha iglasi yefayibha yetekhnoloji yokukhupha i-acid ye-acid ngokukhawuleza. Iikholamu zokucoca zinokusetyenziselwa ukucoca i-DNA enye okanye ezimbini ezixineneyo okanye i-RNA ukusuka kumdaka oqukethe iityuwa, izinyibilikisi, ii-enzymes, okanye iiproteni. I-acid ye-nucleic ibhengezwe kwifayibha yeglasi kwindawo yoxinaniso yetyuwa, kwaye ityuwa kunye nobumdaka buyasuswa kwinqanaba lokucoca. I-DNA / i-RNA ecocekileyo ihlanjwa inwebu ngamanzi okanye nge-buff ye-TE. Ngeempawu zokusebenza ngokulula, inqanaba lokubuyisela kwimeko yesiqhelo kunye nokusebenza okuzinzileyo, imveliso isetyenziswe ziilebhu ezininzi kunye neenkampani ekhaya nakumazwe aphesheya. Ikholamu ye-acid ye-acid yokuhlanjululwa isebenzisa i-silica gel membrane njengezinto ezithile ze-adsorption ye-nucleic acid, ngelixa intengiso yezinye izinto zebhayoloji ayinjalo, enokuqinisekisa ukubuyiswa okuphezulu kwe-DNARNA kwisampulu, ngelixa isusa obunye ubumdaka.
