Ukubaluleka Kokulinganisa Ukusebenza Kwe-Thermal Cycler

Amabhayisikili ashisayozingamathuluzi abalulekile emkhakheni webhayoloji yamangqamuzana nocwaningo lwezakhi zofuzo. Evame ukubizwa ngokuthi imishini ye-PCR (polymerase chain reaction), le mishini ibalulekile ekukhuliseni ukulandelana kwe-DNA, okuvumela ososayensi ukuba benze ucwaningo oluhlukahlukene kusukela ekuhlanganiseni kuya ekuhlaziyeni izakhi zofuzo. Nokho, ukusebenza komjikijeli oshisayo kuncike kakhulu ekulinganisweni kwawo, ngakho abacwaningi kufanele baqonde ukubaluleka kwale nqubo.

Ukulinganisa kuyinqubo yokulungisa nokuqinisekisa ukunemba kwezilinganiso zedivayisi ngokumelene nezinga elaziwayo. Ngomjikelezo oshisayo, lokhu kuhilela ukuqinisekisa ukuthi izilungiselelo zokushisa zinembile futhi aziguquki kuyo yonke inqubo yokugibela ibhayisikili. Ukunemba ekulawuleni izinga lokushisa kubalulekile, njengoba ngisho nokuchezuka okuncane kungaholela kumehluko omkhulu emiphumeleni yokuhlolwa kwe-PCR. Isibonelo, uma izinga lokushisa le-denaturation lingafinyelelwanga, imicu ye-DNA ingase ingahlukani kahle, okuholela ekukhulisweni okungasebenzi kahle. Ngokufanayo, uma izinga lokushisa le-anneal liphansi kakhulu noma liphezulu kakhulu, lingaholela ekubopheni okungaqondile noma ekuntulekeni okuphelele kokubophezela, ekugcineni kubeke engcupheni ubuqotho bokuhlolwa.

Esinye sezizathu eziyinhloko zokuthi kungani ukulinganisa kubaluleke kakhulu kumabhayisikili ashisayo umthelela onawo ekukhiqizeni kabusha. Ocwaningweni lwesayensi, ukukhiqiza kabusha kuyisisekelo sokwethembeka. Uma i-thermal cycler ingalinganiswanga ngendlela efanele, imiphumela etholwe ekuhlolweni okuhlukile ingase ihluke, okwenza kube nzima ukuphindaphinda okutholwe ucwaningo. Lokhu kungahambisani kungaholela eziphethweni eziyiphutha futhi kumoshwe izinsiza, okufaka engozini ukufaneleka okuphelele kocwaningo. Ukulinganisa okuvamile kuqinisekisa ukuthi isithuthuthu esishisayo sisebenza ngaphakathi kwemingcele ethile, ngaleyo ndlela kukhulisa ukwethembeka kwemiphumela yakho.

Ngaphezu kwalokho, ukubaluleka kokulinganisa akukhona nje kuphela ekunembeni kwezilungiselelo zokushisa, kodwa futhi nasekufaneni kokusabalalisa kwezinga lokushisa ngaphakathi komjikelezo oshisayo. Ithuluzi elilinganiswe kahle kufanele likwazi ukunikeza amazinga okushisa angaguquki kuyo yonke imithombo epuleti le-multiwell. Ukwehluka kwezinga lokushisa kungaholela kumehluko kumazinga okukhuliswa, okungathinta imiphumela futhi ekugcineni umphumela uwonke wokuhlolwa. Ngokulinganisa umjikelezo oshisayo, abacwaningi bangaqinisekisa ukuthi wonke amasampuli angaphansi kwezimo ezifanayo zokushisa, ngaleyo ndlela bathuthukise ikhwalithi yedatha.

Ngokungeziwe ekuthuthukiseni ukunemba nokuphindaphinda, ukulinganisa njalo umjikelezo wakho oshisayo kunganweba impilo yesisetshenziswa. Ngokuhamba kwesikhathi, izingxenye ezingaphakathi komjikelezo oshisayo zingaguga noma zingasebenzi kahle, okuholela emaphutheni angaba khona. Ngokulinganisa okokusebenza njalo, abacwaningi bangakwazi ukuhlonza futhi baxazulule izinkinga ngaphambi kokuba zibe izinkinga ezinkulu, baqinisekise ukuthi umjikelezo oshisayo uhlala usesimweni sokusebenza esifanele. Le ndlela yokulinganisa ayigcini nje ngokusindisa izindleko ezihlobene nokukhanda noma ukushintshwa, kodwa futhi inciphisa isikhathi sokuphumula elebhu.

Kafushane, ukulinganisa kweamabhayisikili ashisayokuyisici esibalulekile sokuqinisekisa ukusebenza nokwethembeka kwabo ocwaningweni lwesayensi. Ukulawula izinga lokushisa okunembile nokufana kubalulekile empumelelweni ye-PCR nokunye ukuhlola okuncike kumazinga okushisa. Ngokwenza ukulinganisa okuvamile kube yinto ehamba phambili, abacwaningi bangathuthukisa ukuphinda kukhiqizwe imiphumela, bagcine ubuqotho bemiphumela yabo, futhi bandise ukuphila kwezinto zabo zokusebenza. Njengoba umkhakha webhayoloji yamangqamuzana uqhubeka nokuthuthuka, ukubaluleka kokulinganiswa komjikelezo oshisayo kuzoqhubeka nokuba yisici esibalulekile ekuqhubekiseni phambili inqubekelaphambili yesayensi nokusungula izinto ezintsha.
