Txo Cov Neeg Sawv Cev Bisulfite Sequencing (RRBS)
Txo Cov Neeg Sawv Cev Bisulfite Sequencing (RRBS) tau tshwm sim los ua tus nqi tsim nyog thiab muaj txiaj ntsig zoo rau Whole Genome Bisulfite Sequencing (WGBS) hauv DNA methylation kev tshawb fawb. Thaum WGBS muab kev nkag siab zoo los ntawm kev tshuaj xyuas tag nrho cov genome ntawm ib qho kev daws teeb meem, nws tus nqi siab tuaj yeem yog qhov txwv. RRBS tau tawm tswv yim txo qhov kev sib tw no los ntawm kev xaiv kev tshuaj xyuas ib feem ntawm cov genome. Cov txheej txheem no tso siab rau kev txhawb nqa ntawm CpG cov kob-nplua nuj cheeb tsam los ntawm MspI cleavage ua raws li kev xaiv loj ntawm 200-500/600 bps fragments. Yog li ntawd, tsuas yog thaj tsam ze rau CpG Islands tuaj, thaum cov Islands tuaj CpG nyob deb tsis suav nrog kev tshuaj xyuas. Cov txheej txheem no, ua ke nrog bisulfite sequencing, tso cai rau cov kev daws teeb meem siab ntawm DNA methylation, thiab kev sib txuas ua ke, PE150, tsom tshwj xeeb rau qhov kawg ntawm cov ntawv ntxig es tsis yog nruab nrab, ua kom cov txiaj ntsig ntawm methylation profileing. RRBS yog ib qho cuab yeej tseem ceeb uas ua rau muaj txiaj ntsig zoo DNA methylation tshawb fawb thiab txhawb kev paub txog cov txheej txheem epigenetic.
