Imikhiqizo

I-Illumina ne-BGI

Ubuchwepheshe bokulandelana kwe-Illumina, obusekelwe ku-Sequencing by Synthesis (SBS), iwukuqanjwa okusha kwe-NGS okwamukelwa emhlabeni wonke, okubophezelekile ukukhiqiza ngaphezu kuka-90% wedatha yokulandelana komhlaba.Umgomo we-SBS ubandakanya ukuthwebula izithombe ezishintshashintshayo ezilebulwe ngokushintshashintsha kwe-fluorescent njengoba i-dNTP ngayinye yengezwa, futhi kamuva igoqe ukuze kuvunyelwe ukufakwa kwesisekelo esilandelayo.Ngawo wonke ama-dNTP amane abophezelayo abophezelayo akhona kumjikelezo ngamunye wokulandelana, ukuncintisana kwemvelo kunciphisa ukuchema kokufakwa.Lobu buchwepheshe obuhlukahlukene busekela imitapo yolwazi efundwa kanye kanye naleyo ebhanqiwe, ihlinzekela uhla lwezinhlelo zokusebenza ze-genomic.Amakhono we-Illumina wokulandelanisa okuphuma phambili nokunemba akubeka njengesisekelo ocwaningweni lwe-genomics, kunikeza ososayensi amandla okuqaqa ubunkimbinkimbi bezakhi zofuzo ngemininingwane engenakuqhathaniswa nokusebenza kahle.

I-DNBSEQ, eyakhiwe yi-BGI, ingobunye ubuchwepheshe be-NGS obusha obukwazile ukwehlisa ngokuqhubekayo izindleko zokulandelana nokwandisa ukusebenza.Ukulungiswa kwemitapo yolwazi ye-DNBSEQ kuhilela ukuhlukaniswa kwe-DNA, ukulungiswa kwe-ssDNA kanye nokukhulisa isiyingi esigoqayo ukuze kutholwe ama-nanoballs e-DNA (DNB).Lezi zibe sezilayishwa endaweni eqinile bese zilandelana ngokulandelana nge-Probe-Anchor Synthesis (cPAS).

Isevisi yethu yokulandelana kwelabhulali eyenziwe ngaphambilini isiza amakhasimende ekulungiseleleni amalabhulali awo alandelanayo avela emithonjeni eyahlukene (mRNA, whole genome, amplicon, phakathi kokunye).Ngokulandelayo, le mitapo yolwazi ingathunyelwa ezikhungweni zethu zokulandelanisa ukuze zilawule ikhwalithi nokulandelana kuzingxenyekazi ze-Illumina noma ze-BGI.


Imininingwane Yesevisi

Umphumela wedemo

Izici

Izinkundla:I-Illumina NovaSeq 6000, NovaSeq , HiSeq X Ten kanye ne-BGI-DNB-T7

Amamodi wokulandelanisa:PE50, PE100, PE150, PE250

Ukulawulwa kwekhwalithi yemitapo yolwazi ngaphambi kokulandelana

Ilandelanisa ukulethwa kwedatha ne-QC:ukulethwa kombiko we-QC kanye nedatha eluhlaza ngefomethi ye-fastq ngemuva kokufundwa kwe-demultiplexing nokuhlunga i-Q30.

 

Izinzuzo Zesevisi

Ukuhlukahluka kwezinsizakalo zokulandelanisa:ikhasimende lingakhetha ukulandelana ngomzila, iseli eligelezayo noma inani ledatha.

Ukuhlukahluka kwezinkundla:Imitapo yolwazi ye-DNB ingadluliselwa kumapulatifomu e-Illumina

Umuzwa obanzi kuplathifomu yokulandelana kwe-Illumina:ngezinkulungwane zamaphrojekthi avaliwe anezinhlobo ezahlukahlukene. 

Ukulethwa kokulandelanisa umbiko we-QC:ngamamethrikhi ekhwalithi, ukunemba kwedatha kanye nokusebenza kukonke kwephrojekthi yokulandelanisa.

Inqubo yokulandelanisa yabantu abadala:ngokuhamba kwesikhathi esifushane.

Ukulawulwa Kwekhwalithi Okuqinile: sisebenzisa izimfuneko eziqinile ze-QC ukuze siqinisekise ukulethwa kwemiphumela ehlala njalo yekhwalithi ephezulu.
