Ukuguqula i-PCR: I-FastCycler Thermal Cycler

Emkhakheni webhayoloji yama-molecule,ama-thermal cyclers ziyithuluzi elibalulekile enqubweni yokusabela kwe-polymerase chain (PCR). Njengoba abacwaningi kanye nama-laboratory bephishekela ukusebenza kahle nokunemba, i-FastCycler isishintshe kakhulu kulo mkhakha. Ngobuchwepheshe bayo obusezingeni eliphezulu kanye nokusebenza kwayo okuphezulu, i-FastCycler ibeka indinganiso entsha yokujikeleza kokushisa.

I-FastCycler iqhutshwa yizinto zePeltier ezisezingeni eliphezulu ezivela eMarlow, e-USA. Lezi zinto zenzelwe ngokucophelela ukuhlinzeka ngokulawula izinga lokushisa okuhle kakhulu, ngamazinga okushisa afinyelela ku-6 °C/s. Leli khono lokushintsha okusheshayo linciphisa kakhulu isikhathi esidingekayo kumjikelezo ngamunye we-PCR, okuvumela abacwaningi ukuthi baqedele ukuhlola ngokushesha ngaphandle kokubeka engcupheni ikhwalithi.

Esinye sezici ezivelele ze-FastCycler ukubalwa kwayo kwemijikelezo okumangalisayo, okungaphezu kwemijikelezo eyizigidi eziyi-100. Lokhu kuqina kuqinisekisa ukuthi amalabhorethri angayisebenzisa i-FastCycler isikhathi eside, okwenza kube ukutshalwa kwezimali okungabizi kakhulu kunoma yisiphi isikhungo socwaningo. Ukuphila isikhathi eside kwe-FastCycler kusho ukuthi abacwaningi bangagxila ekuhlolweni kwabo ngaphandle kokukhathazeka ngokwehluleka kwemishini noma isidingo sokushintshwa njalo.

Ukunemba kwezinga lokushisa kubalulekile ku-PCR, futhi i-FastCycler iyaphumelela kulokhu. Isebenzisa ubuchwepheshe obuthuthukisiwe bokushisa nokupholisa be-thermoelectric, obuhlanganiswe nokulawula izinga lokushisa kwe-PID (proportional-integral-derivative), i-FastCycler igcina izinga eliphezulu lokunemba kwezinga lokushisa kuyo yonke inqubo yokujikeleza. Lokhu kunemba kubalulekile ekufinyeleleni imiphumela ethembekile nephindaphindwayo, okubalulekile ocwaningweni lwesayensi.

Ukufana kuzo zonke izimbobo kungenye isici esibalulekile sokujikeleza kokushisa, futhi i-FastCycler ayidumazi. I-FastCycler yakhelwe ukuqinisekisa iphrofayili yokushisa ehambisanayo emthonjeni ngamunye, inciphise ingozi yokuguquguquka kwemiphumela ye-PCR. Lokhu kufana kubaluleke kakhulu lapho usebenza ngamasampula adinga ukukhuliswa okunembile, njengoba kusiza ukuqinisekisa ukuthi zonke izimpendulo zenziwa ngaphansi kwezimo ezifanayo.

Ngaphezu kwalokho, i-FastCycler isebenza ngokuthula, okwenza ibe yindawo efaneleke kakhulu kuma-lab adinga indawo yokusebenza ethule. Lesi sici sivumela abacwaningi ukuthi benze izivivinyo ngaphandle kokuphazanyiswa umsindo womshini, okudala isimo esigxile kakhulu nesikhiqizayo.

Ngaphezu kwemininingwane yayo yobuchwepheshe, i-FastCycler yaklanywa kucatshangelwa ukuthi kulula ukuyisebenzisa. I-interface yayo enembile kanye nezinketho zokuhlela ezilula kwenza kube lula kokubili abacwaningi abanolwazi kanye nabaqalayo ukusebenzisa. Ikhono lokwenza ngokwezifiso amaphrothokholi nokuqapha inqubekela phambili kalula lithuthukisa ulwazi lomsebenzisi jikelele, okuvumela ososayensi ukuthi bagxile ocwaningweni lwabo kunokusebenzisa umshini oyinkimbinkimbi.

Ngamafuphi, i-FastCyclerI-Thermal Cyclerimele intuthuko enkulu kubuchwepheshe be-PCR. Ngezakhi zayo ze-Peltier ezisezingeni eliphezulu, ukusheshisa okusheshayo, inkomba yokujikeleza okuhle kakhulu, kanye nokulawula izinga lokushisa okuthuthukisiwe, inikeza ukusebenza okungenakuqhathaniswa kwezicelo zebhayoloji yama-molecule. Ukuhlanganiswa kokunemba, ukufana, kanye nokusebenza komsindo ophansi kwenza i-FastCycler ibe ithuluzi elibalulekile kunoma yiliphi ilabhorethri elihlose ukuthola imiphumela esezingeni eliphezulu ngempumelelo. Njengoba isidingo se-PCR esheshayo nethembekile siqhubeka nokukhula, i-FastCycler ivelele njengomholi kulo mkhakha, okwenza abacwaningi bakwazi ukusunduza imingcele yokutholwa kwesayensi.
