Te Hurihanga o te PCR: FastCycler Thermal Cycler

I roto i te mara o te koiora ngota,ngā huringa wera he taputapu tino nui i roto i te tukanga tauhohenga mekameka polymerase (PCR). I a ngā kairangahau me ngā taiwhanga e whai ana i te whai huatanga me te tika, kua huri a FastCycler hei mea whakarerekē i te ao. Mā tana hangarau hou me te mahi pai rawa atu, kei te whakatakoto a FastCycler i tētahi paerewa hou mō te huringa wera.

E whakakahangia ana te FastCycler e ngā huānga Peltier kounga teitei mai i Marlow, USA. He mea hanga āta ēnei huānga kia pai ai te whakahaere i te pāmahana, me ngā tere piki pāmahana tae atu ki te 6 °C/s. Mā tēnei kaha piki tere ka tino whakaitihia te wā e hiahiatia ana mō ia huringa PCR, ka taea ai e ngā kairangahau te whakaoti tere i ngā whakamātautau me te kore e whakararu i te kounga.

Ko tētahi o ngā āhuatanga tino pai o te FastCycler ko tōna tatau huringa whakamiharo, neke atu i te 100 miriona huringa. Mā tēnei pakari ka taea e ngā taiwhanga te whakamahi i te FastCycler mō te wā roa, ka waiho hei haumitanga utu-whai hua mō tētahi whare rangahau. Ko te roa o te ora o te FastCycler te tikanga ka taea e ngā kairangahau te arotahi ki ā rātou whakamātautau me te kore e manukanuka ki te rahunga o ngā taputapu, ki te hiahia rānei kia whakakapia pinepine.

He mea nui te tika o te pāmahana i roto i te PCR, ā, he tino pai te FastCycler i tēnei āhuatanga. Mā te whakamahi i 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 ngā hua pono me te taea te whakaputa anō, he mea nui tēnei i roto i te rangahau pūtaiao.

Ko te ōritetanga puta noa i ngā puna katoa tētahi atu āhuatanga nui o te huringa wera, ā, kāore te FastCycler e whakapōrearea. Kua hangaia te FastCycler kia rite te āhua o te pāmahana puta noa i ia puna, kia iti ake ai te mōrearea o te rerekētanga o ngā hua PCR. He mea nui rawa tēnei ōritetanga ina mahi ana me ngā tauira e hiahia ana kia tino whakanuia, nā te mea ka āwhina kia whakarite kia mahia ngā tauhohenga katoa i raro i ngā āhuatanga ōrite.

Hei tāpiritanga, he mārire te mahi a te FastCycler, he mea tino pai mō ngā taiwhanga e hiahia ana ki tētahi taiao mahi mārire. Mā tēnei āhuatanga ka taea e ngā kairangahau te whakahaere i ngā whakamātautau me te kore e whakararuraruhia e te haruru mīhini, ka hangaia he āhuarangi arotahi ake, whai hua ake hoki.

Haunga ōna whakatakotoranga hangarau, i hangaia te FastCycler me te whakaaro ki te ngāwari ki te whakamahi. Nā tōna atanga ngāwari me ngā kōwhiringa hōtaka ngāwari ka māmā ake te whakamahi mā ngā kairangahau mātau me ngā tauhou. Mā te kaha ki te whakarite i ngā kawa me te aroturuki ngāwari i te ahunga whakamua ka whakarei ake i te wheako kaiwhakamahi whānui, ka taea ai e ngā kaipūtaiao te arotahi ki ā rātou rangahau kaua ki te whakahaere i tētahi mīhini uaua.

Hei whakarāpopototanga, ko te FastCyclerKaihurihuri WeraHe whanaketanga nui tēnei i roto i te hangarau PCR. Mā ōna huānga Peltier kounga teitei, te tere o te pikinga, te taupū huringa pai rawa atu, me te whakahaere pāmahana matatau, ka whakaratohia he mahi tino pai mō ngā tono koiora ngota. Mā te whakakotahitanga o te tika, te ōritetanga, me te mahi iti-haruru ka waiho te FastCycler hei taputapu nui mō tētahi taiwhanga e whai ana kia whiwhi hua kounga teitei. I te mea kei te tipu haere tonu te hiahia mō te PCR tere me te pono, ka tū te FastCycler hei kaiārahi i roto i te mara, ka taea ai e ngā kairangahau te pana i ngā rohe o te kitenga pūtaiao.
