1. Usoro mmiri mmiri, nke a makwaara dị ka usoro pipetting, bụ iji wepụ nucleic acid site n'ime ka ọkpụkpụ magnetik na-ebufe mmiri mmiri.N'ozuzu, a na-enweta nnyefe ahụ site na ịchịkwa ogwe aka robot site na sistemụ arụmọrụ.Usoro mmịpụta bụ nke a:

1) Lysis: Tinye ngwọta lysis na ihe nlele ahụ, ma ghọta ngwakọta na mmeghachi omume zuru oke nke ngwọta mmeghachi omume site na mmegharị igwe na kpo oku, a na-eme ka mkpụrụ ndụ lysed, a na-ahapụkwa acid nucleic.

2) Adsorption: Tinye ihe ndọta magnetik na lysate sample, gwakọta nke ọma, ma jiri bead magnet nwee njikọ siri ike maka acid nucleic n'okpuru nnu dị elu na pH dị ala iji gbasaa acid nucleic.N'okpuru ọrụ nke oghere ndọta dị n'èzí, a na-ekewa beads magnet na ngwọta., jiri ọnụ ọnụ wepụ mmiri mmiri ma tụba ya na tankị mkpofu, ma tụfuo ọnụ.

3) Ịsacha: Wepu oghere magnetik dị n'èzí, dochie ya na ọnụ ọhụrụ ma gbakwunye ihe nchekwa ịsa ahụ, jikọta nke ọma iji wepụ ihe ndị na-adịghị ọcha, ma wepụ mmiri mmiri n'okpuru ọrụ nke oghere magnetik.

4) Elution: Wepu oghere ndọta dị n'èzí, jiri ọnụ ọhụrụ dochie ya, tinye ihe nchekwa elution, gwakọta nke ọma, wee kewaa acid nucleic agbụ na bead magnet iji nweta acid nucleic sachara.
2. Usoro mmanya magnet

Usoro mkpara magnetik na-achọpụta nkewa nke acid nucleic site na idozi mmiri mmiri na ịnyefe bead magnet.Ụkpụrụ na usoro bụ otu ihe ahụ dị ka usoro nsị, ma ihe dị iche bụ usoro nkewa n'etiti bead magnet na mmiri mmiri.Usoro ihe ndọta magnetik bụ ikewapụ beads magnet na mmiri mkpofu site na adsorption nke mkpanaka magnet na bead magnet, ma tinye ha n'ime mmiri na-esote iji ghọta mmịpụta nke nucleic acid.
