Ukuguqula i-PCR: I-FastCycler Thermal Cycler

Emkhakheni webhayoloji yama-molecule,ama-thermal cyclerszingamathuluzi abalulekile kubacwaningi nososayensi. Zidlala indima ebalulekile enkambisweni ye-polymerase chain reaction (PCR), okuyisisekelo sokwandiswa kwe-DNA, ukwakheka kwe-cloning kanye nokuhlaziywa okuhlukahlukene kwezakhi zofuzo. Phakathi kwama-cyclers amaningi okushisa emakethe, i-FastCycler ivelele ngezici zayo ezithuthukisiwe kanye nezingxenye ezisezingeni eliphezulu, iba yimodeli yokusungula izinto ezintsha kanye nokusebenza kahle.

Inhliziyo ye-FastCycler ukuzibophezela kwayo ekhwalithini, isebenzisa izakhi ze-Peltier zekhwalithi ephezulu ezivela eMarlow, e-USA. Lezi zakhi zaziwa ngokuthembeka kwazo nokusebenza kwazo, okuvumela i-FastCycler ukuthi ifinyelele amazinga okushisa amangalisayo afinyelela ku-6°C/S. Leli khono lokusheshisa libalulekile ekunciphiseni isikhathi esiphelele esidingekayo sokusheshisa i-PCR, okuvumela abacwaningi ukuthi bathole imiphumela ngokushesha ngaphandle kokubeka engcupheni ubuqotho bokuhlolwa.

Esinye sezici ezivelele ze-FastCycler ukubalwa kwayo kwemijikelezo okumangalisayo, okungaphezu kwemijikelezo eyizigidi eziyi-100. Lokhu kuqina kusho ukuthi abacwaningi bangayisebenzisa i-FastCycler isikhathi eside, okwenza kube ukutshalwa kwezimali okungabizi kakhulu kuma-laboratories adinga ukujikeleza okushisayo okuqhubekayo nokuphindaphindayo. Ukuphila isikhathi eside kwe-FastCycler kuwubufakazi bomklamo wayo oqinile kanye nobunjiniyela, okuqinisekisa ukuthi ingakwazi ukumelana nobunzima bokusetshenziswa kwansuku zonke kwelabhorethri.

Ukunemba kwezinga lokushisa kubalulekile ekusetshenzisweni kwe-PCR, futhi i-FastCycler iyaphumelela kulokhu. Ngobuchwepheshe 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 ukwandiswa okuhle kwe-DNA, njengoba ngisho nokuphambuka okuncane ekushiseni kungaholela emiphumeleni emibi noma ekuhlulekeni kokuhlola.

Ukufana kuzo zonke izimbobo kungenye isici esibalulekile sokujikeleza kokushisa, futhi i-FastCycler ayidumazi. Ukwakheka kwayo kuqinisekisa ukuthi wonke amasampula ayashiswa futhi apholiswa njalo, okubaluleke kakhulu ekuhlolweni okudinga izimo ezifanayo. Lokhu kufana kunciphisa ukuguquguquka kwemiphumela, okunikeza abacwaningi ukuzethemba kokuthi idatha yabo ithembekile futhi ingaphindaphindwa.

Ngaphezu kwalokho, i-FastCycler isebenza ngamazinga aphansi omsindo, okwenza kube yindawo efaneleke kakhulu ezindaweni zelebhu ezidinga umoya othule. Lesi sici asigcini nje ngokuthuthukisa izimo zokusebenza zabacwaningi, kodwa futhi senza ulwazi lwelebhu lugxile futhi lusebenze kahle.

Ngamafuphi, iI-FastCycler Thermal Cyclerimele intuthuko enkulu kubuchwepheshe be-PCR. Ngezakhi zayo zePeltier ezisezingeni eliphezulu, amazinga okushesha okusheshayo, inkomba yokujikeleza enhle kakhulu, kanye nendlela yokulawula izinga lokushisa ethuthukisiwe, iklanyelwe ukuhlangabezana nezidingo zocwaningo lwebhayoloji yama-molecule yesimanje. Kungakhathaliseki ukuthi wenza ukukhuliswa kwe-DNA okuvamile noma uhlanganyela ocwaningweni oluyinkimbinkimbi lwezakhi zofuzo, i-FastCycler inikeza ukusebenza okuphezulu, ukuthembeka, kanye nokusebenza kahle. Ukutshala imali ku-FastCycler kusho ukutshala imali esikhathini esizayo socwaningo lwakho, ukuqinisekisa ukuthi unamathuluzi owadingayo ukuze udlule imingcele yokutholwa kwesayensi.
