I-thermal cycler, eyaziwa nangokuthi umshini we-PCR, iyithuluzi laselabhorethri elisetshenziselwa ukukhulisa izingcezu ze-DNA ngenqubo ye-polymerase chain reaction (PCR). Leli thuluzi elinamandla libalulekile ocwaningweni lwebhayoloji yamangqamuzana ofuzo kanye nokuxilongwa kwezokwelapha kanye nokuhlaziywa kwe-forensic.
Amabhayisikili ashisayo asebenza ngokuhamba ngebhayisikili ochungechungeni lwezinguquko zokushisa ukuze kube lula inqubo ye-PCR. Izingxenye ezibalulekile zomjikelezo oshisayo zihlanganisa ibhulokhi yokushisisa evumela ukushintsha kwezinga lokushisa okusheshayo nesivalo esishisayo esiqinisekisa ngisho nokusatshalaliswa kokushisa kusampula. Umshini ungalawula ngokunembile izinga lokushisa lengxube yokusabela ukuze ufinyelele izinyathelo zokukhishwa kwe-denaturation, annealing nezandiso ze-PCR.

Ngakho-ke, yini i-thermal cycler esetshenziselwa? Inhloso eyinhloko ye-thermal cycler ukukhulisa ukulandelana kwe-DNA ethile. Lokhu kufezwa ngokufudumeza okuphindaphindiwe nokupholisa ingxube yokusabela ukuze iguqule i-DNA, iyihlanganise neziqalo, bese iyinweba nge-DNA polymerase. Ngakho-ke, kudingeka amakhophi ambalwa okuqala ukuze kukhiqizwe izigidi zamakhophi okulandelana kwe-DNA okuhlosiwe.
In ucwaningo, amabhayisikili ashisayo asetshenziselwa ukutadisha ukuchazwa kwezakhi zofuzo, ukuhlukahluka kofuzo kanye nokulandelana kwe-DNA. Ibuye isetshenziselwe i-cloning, i-mutagenesis kanye nokuhlaziywa kwezakhi zofuzo. Ekuxilongweni kwezokwelapha, amabhayisikili ashisayo asetshenziselwa ukuthola izifo ezithathelwanayo, izifo zofuzo, kanye nezimpawu zomdlavuza. Ukwengeza, kusayensi ye-forensic, lawa mathuluzi abalulekile ekuhlaziyweni kwe-DNA nokuhlonza abantu ngobufakazi bebhayoloji.
Ukuguquguquka nokunemba kwamabhayisikili ashisayo kuye kwashintsha umkhakha webhayoloji yamangqamuzana, okuvumela ososayensi ukuba bahlole futhi baqonde isisekelo sofuzo sempilo nezifo. Ubuchwepheshe bubambe iqhaza elikhulu ekuthuthukisweni kwemithi yomuntu siqu futhi ibe nomthelela omkhulu ezimbonini ezihlukahlukene ezihlanganisa ezempilo, ezolimo kanye nesayensi yezemvelo.
Kafushane, amabhayisikili ashisayo ayithuluzi elibalulekile ekukhuliseni i-DNA futhi asetshenziswa kabanzi ocwaningweni lwesayensi, kwezokwelapha, kanye nokuhlaziywa kwe-forensic. Ikhono layo lokukopisha ukulandelana kwe-DNA ngokushesha nangokunembile liyenza ibe yimpahla ebalulekile ekuthuthukiseni ukuqonda kwethu izakhi zofuzo kanye nokusebenza kwazo okungokoqobo emikhakheni ehlukene.
I-Beijing Liuyi Biotechnology Co. Ltd (i-Liuyi Biotechnology) ikhethekile ekukhiqizeni amathuluzi e-electrophoresis iminyaka engaphezu kwengu-50 neqembu lethu lezobuchwepheshe eliqeqeshiwe kanye nesikhungo se-R&D. Sinomugqa wokukhiqiza onokwethenjelwa nophelele kusukela ekuklanyweni kuya ekuhlolweni, kanye nendawo yokugcina impahla, kanye nokwesekwa kokumaketha. Imikhiqizo yethu eyinhloko i-Electrophoresis Cell (ithangi/igumbi), i-Electrophoresis Power Supply, i-Blue LED Transilluminator, i-UV Transilluminator, i-Gel Image & Analysis System njll. Siphinde sinikeze amathuluzi aselabhu njenge-PCR instrument, i-vortex mixer kanye ne-centrifuge yaselabhorethri.
Uma unecebo lokuthenga lemikhiqizo yethu, sicela ungangabazi ukusithinta. Ungasithumela umlayezo nge-imeyili[i-imeyili ivikelwe]noma[i-imeyili ivikelwe], noma sicela usishayele ku- +86 15810650221 noma wengeze uWhatsapp +86 15810650221, noma Wechat: 15810650221.
