Te Hurihanga o te PCR: FastCycler Thermal Cycler

I roto i te mara o te koiora ngota,ngā huringa werahe taputapu tino nui mō ngā kairangahau me ngā kaipūtaiao. He mahi nui tā rātou i roto i te tukanga tauhohenga mekameka polymerase (PCR), koinei te pūtake o te whakanui i te DNA, te tāruarua me ngā tātaritanga ira. I roto i ngā maha o ngā huringa wera kei te mākete, ko FastCycler te mea e tū motuhake ana me ōna āhuatanga matatau me ngā wāhanga kounga teitei, ka noho hei tauira o te auahatanga me te whai huatanga.

Kei te ngako o te FastCycler tōna whakapau kaha ki te kounga, mā te whakamahi i ngā huānga Peltier kounga teitei mai i Marlow, USA. E mōhiotia ana ēnei huānga mō tō rātou pono me te mahi, e āhei ai te FastCycler ki te whakatutuki i ngā tere piki pāmahana whakamiharo tae atu ki te 6°C/S. He mea nui tēnei āheinga piki tere hei whakaiti i te wā katoa e hiahiatia ana mō te huringa PCR, e āhei ai ngā kairangahau ki te whiwhi hua tere ake me te kore e whakararu i te pono o te whakamātautau.

Ko tētahi o ngā āhuatanga tino hira o te FastCycler ko tōna tatau huringa whakamiharo, neke atu i te 100 miriona huringa. Nā tēnei pakari ka taea e ngā kairangahau te whakamahi i te FastCycler mō ngā wā roa, ka waiho hei haumitanga utu-whai hua mō ngā taiwhanga e hiahia ana ki te huringa wera tonu me te auau. Ko te roa o te ora o te FastCycler he tohu i tōna hoahoa pakari me te hangarau, e whakarite ana ka taea e ia te tu atu i ngā uauatanga o te whakamahinga taiwhanga o ia rā.

He mea nui te tika o te pāmahana i roto i ngā tono PCR, ā, he tino pai te FastCycler i tēnei āhuatanga. Mā te hangarau whakamahana me te whakamatao hiko matatau me te whakahaere pāmahana PID (proportional-integral-derivative), ka mau tonu te FastCycler i te taumata teitei o te tika o te pāmahana puta noa i te tukanga huringa. He mea nui tēnei tika hei whakatutuki i te whakanui pai o te DNA, nā te mea ahakoa he iti noa ngā rerekētanga o te pāmahana ka arahi pea ki ngā hua kino, ki te kore rānei e angitu te whakamātautau.

Ko te ōritetanga puta noa i ngā puna katoa tētahi atu āhuatanga nui o te huringa wera, ā, kāore te FastCycler e whakapōrearea. Mā tōna hoahoa ka whakamahanahia, ka whakamataohia hoki ngā tauira katoa i ngā wā katoa, he mea nui tēnei mō ngā whakamātautau e hiahia ana ki ngā āhuatanga ōrite. Mā tēnei ōritetanga ka whakaitihia te rerekētanga o ngā hua, ka whakawhirinaki ngā kairangahau he pono, he taea hoki te tāruarua ā rātou raraunga.

Hei tāpiritanga, he iti te haruru o te mahi a FastCycler, he mea tino pai mō ngā taiao taiwhanga e hiahia ana ki tētahi āhua marino. Ehara i te mea ka whakapai ake tēnei āhuatanga i ngā āhuatanga mahi a ngā kairangahau anake, engari ka nui ake te arotahi me te whai hua o te wheako taiwhanga.

Hei whakarāpopototanga, ko teKaihurihuri Wera FastCyclerHe whanaketanga nui tēnei i roto i te hangarau PCR. Mā ōna huānga Peltier kounga teitei, ngā tere piki tere, te taupū huringa pai rawa atu, me te tikanga whakahaere pāmahana matatau, kua hangaia hei whakatutuki i ngā hiahia o te rangahau koiora ngota hou. Ahakoa kei te mahi koe i te whakanui DNA auau, kei te whai wāhi rānei koe ki te rangahau ira matatini, ka tukuna e te FastCycler te mahi teitei, te pono, me te whai hua. Ko te haumi ki tētahi FastCycler ko te haumi ki te heke mai o tō rangahau, me te whakarite kei a koe ngā taputapu e hiahiatia ana e koe hei pana i ngā rohe o te kitenga pūtaiao.
