I-Revolutionizing PCR: I-FastCycler Thermal Cycler

Emkhakheni we-molecular biology,amabhayisikili ashisayo ziyithuluzi elibalulekile kunqubo ye-polymerase chain reaction (PCR). Njengoba abacwaningi namalabhorethri bephishekela ukusebenza kahle nokunemba, i-FastCycler isiphenduke umguquli wegeyimu emkhakheni. Ngobuchwepheshe bayo obusezingeni eliphezulu nokusebenza okuphezulu, i-FastCycler ibeka izinga elisha lokuhamba ngebhayisikili elishisayo.

I-FastCycler inikwa amandla yi-elementi yekhwalithi ephezulu ye-Peltier evela e-Marlow, e-USA. Lezi zakhi ziklanywe ngokucophelela ukuze zinikeze ukulawulwa kwezinga lokushisa okuhle kakhulu, namazinga okushisa afinyelela ku-6 °C/s. Leli khono lerempu elisheshayo linciphisa kakhulu isikhathi esidingekayo kumjikelezo we-PCR ngamunye, okuvumela abacwaningi ukuthi baqedele ukuhlola ngokushesha ngaphandle kokubeka engcupheni ikhwalithi.

Esinye sezici ezivelele ze-FastCycler ukubalwa kwayo komjikelezo ohlaba umxhwele, okudlula imijikelezo eyizigidi eziyi-100. Lokhu kuqina kuqinisekisa ukuthi amalebhu angasebenzisa i-FastCycler isikhathi eside, okuyenza ibe ukutshalwa kwezimali okungabizi kakhulu kunoma yisiphi isikhungo socwaningo. Impilo ende ye-FastCycler isho ukuthi abacwaningi bangagxila ekuhloleni kwabo ngaphandle kokukhathazeka ngokwehluleka kwemishini noma isidingo sokushintshwa njalo.

Ukunemba kwezinga lokushisa kubalulekile ku-PCR, futhi i-FastCycler iyaphumelela kulokhu. Isebenzisa ubuchwepheshe bokufudumeza okuthuthukisiwe kwe-thermoelectric kanye nokupholisa, kuhlanganiswe ne-PID (i-proportional-integral-derivative) yokulawula izinga lokushisa, i-FastCycler igcina izinga eliphezulu lokunemba kwezinga lokushisa kuyo yonke inqubo yebhayisikili. Lokhu kunemba kubalulekile ekuzuzeni imiphumela enokwethenjelwa futhi ekwazi ukukhiqiza kabusha, ebalulekile ocwaningweni lwesayensi.

Ukufana kuyo yonke imithombo kungenye isici esibalulekile sokuhamba ngebhayisikili okushisayo, futhi i-FastCycler ayidumazi. I-FastCycler yakhelwe ukuqinisekisa iphrofayili yokushisa engaguquki kuwo wonke umthombo, ukunciphisa ubungozi bokuhlukahluka kwemiphumela ye-PCR. Lokhu kufana kubaluleke kakhulu uma usebenza namasampuli adinga ukukhuliswa okunembile, njengoba kusiza ukuqinisekisa ukuthi konke ukusabela kwenziwa ngaphansi kwezimo ezifanayo.

Ngaphezu kwalokho, i-FastCycler isebenza buthule, iyenze ilungele amalebhu adinga indawo yokusebenza ethule. Lesi sici sivumela abacwaningi ukuthi benze izivivinyo ngaphandle kokuphazanyiswa umsindo womshini, okudala isimo esigxile kakhulu nesikhiqizayo.

Ngokungeziwe ekucacisweni kwayo kobuchwepheshe, i-FastCycler yakhelwe kucatshangelwa ubungane nomsebenzisi. I-interface yayo enembile kanye nezinketho zokuhlela ezilula zikwenza kube lula kubo bobabili abacwaningi abanolwazi nabaqalayo ukuthi basebenzise. Ikhono lokwenza amaphrothokholi ngokwezifiso kanye nokuqapha inqubekelaphambili kalula lithuthukisa ulwazi olunzulu ngomsebenzisi, okuvumela ososayensi ukuthi bagxile ocwaningweni lwabo esikhundleni sokusebenzisa umshini oyinkimbinkimbi.

Kafushane, i-FastCyclerI-Thermal Cyclerimele intuthuko enkulu kubuchwepheshe be-PCR. Ngama-elementi ekhwalithi ephezulu ye-Peltier, ukugijima ngokushesha, inkomba yebhayisikili enhle kakhulu, nokulawula izinga lokushisa okuthuthukisiwe, inikeza ukusebenza okungenakuqhathaniswa kwezinhlelo zokusebenza zebhayoloji yamangqamuzana. Ukuhlanganiswa kokunemba, ukufana, nokusebenza komsindo ophansi kwenza i-FastCycler ibe yithuluzi elibalulekile lanoma iyiphi ilabhorethri okuhloswe ngayo ukuthola imiphumela yekhwalithi ephezulu. Njengoba isidingo se-PCR esheshayo nethembekile siqhubeka sikhula, i-FastCycler igqama njengomholi kulo mkhakha, ivumela abacwaningi ukuthi basunduze imingcele yokutholwa kwesayensi.
