Hanyoyi gama gari don ware da tsarkake sinadarin nucleic acid

Cire Phenol-chloroform:Wannan hanyar gargajiya tana amfani da sinadarai masu narkewar halitta don raba sinadarin nucleic acid daga sunadarai da sauran sassan tantanin halitta. Ana haɗa samfurin da phenol da chloroform, wanda ke haifar da rabuwar nucleic acid zuwa cikin yanayin ruwa, yayin da sunadarai ke ci gaba da kasancewa a cikin yanayin halitta. Bayan centrifugation, ana tattara matakin ruwa mai ɗauke da nucleic acid kuma ana haƙa shi da ethanol.

Hanyoyi masu amfani da gel na silica:Ana amfani da membranes na gel na silica sosai a cikin kayan aikin tsarkake sinadarin nucleic acid na kasuwanci. Ka'idar wannan hanyar ita ce, nucleic acid suna ɗaurewa da gel ɗin silica a yawan gishiri. Bayan ɗaurewa, ana wanke gurɓatattun abubuwa, sannan a cire nucleic acid ɗin da ruwa mai ƙarancin gishiri. Wannan hanyar ta fi dacewa saboda tana da sauri, inganci, kuma tana samar da nucleic acid masu tsafta.

Tsarkakewar magnetic beads:Wannan dabarar tana amfani da beads na maganadisu da aka lulluɓe da sinadaran ɗaure nucleic acid. Idan aka haɗa samfurin da beads na maganadisu, nucleic acid ɗin suna shiga saman beads ɗin. Sannan ana raba beads ɗin daga maganin ta amfani da maganadisu, don haka ana cire gurɓatattun abubuwa. Wannan hanyar tana da amfani kuma ana iya sarrafa ta ta atomatik, wanda hakan ya sa ta dace da aikace-aikacen da ke da ƙarfin aiki sosai.

Tsarin chromatography na ginshiƙi:Wannan hanyar ta ƙunshi wucewar samfurin ta cikin ginshiƙin chromatographic cike da wani tsari mai tsayi wanda ke riƙe da ƙwayoyin nucleic acid daban-daban. Ana iya amfani da nau'ikan ginshiƙai daban-daban, gami da waɗanda suka dogara da ka'idojin cire girman ko musayar ion. Kwayoyin nucleic acid suna fitowa daga ginshiƙin, wanda ke haifar da samfurin da aka tsarkake.

Hanyoyin enzyme:Ana iya amfani da hanyoyin enzyme, kamar waɗanda ke amfani da DNase ko RNase, don rage ƙwayoyin nucleic acid ko gurɓatattun abubuwa da ba a so. Wannan hanyar tana da tasiri musamman lokacin sarrafa samfuran hadaddun abubuwa, kamar waɗanda ke ɗauke da DNA da RNA.
