Tūhurahia te maha o ngā whakamahinga o ngā mīhini huringa wera i roto i ngā rangahau

He taputapu nui ngā mīhini huringa wera, e mōhiotia ana ko ngā mīhini PCR, i roto i te koiora ngota me te rangahau ira. Ka whakamahia ēnei taputapu hei whakanui i te DNA me te RNA mā te hangarau tauhohenga mekameka polymerase (PCR). Heoi, kāore i te herea noa te maha o ngā whakamahinga PCR ki ngā huringa wera. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā huarahi rerekē e whakamahia ai ngā mīhini huringa wera i roto i te rangahau me tō rātou hiranga ki te whakatairanga i te mātauranga pūtaiao.

1. Te whakanui i te PCR

Ko te mahi matua o tētahimīhini huringa weraKo te mahi i te whakanui PCR, he mea nui tēnei mō ngā momo tono koiora ngota. Mā te tuku i tētahi tauira DNA, RNA rānei ki tētahi raupapa huringa pāmahana, ka whakatairangahia e ngā huringa wera te whakakorenga, te whakamahana, me te toronga o ngā whenu waikawa karihi, ka hua ake he whakanui taupū o ngā raupapatanga ūnga motuhake. He mea nui tēnei tukanga mō te tātari ira, ngā rangahau whakaaturanga ira, me te kimi i ngā kaihoko mate.

2. PCR Tauanga (qPCR)

Haunga te PCR paerewa, ka whakamahia ngā mīhini huringa wera mō te PCR tauanga, te qPCR rānei, e āhei ai te ine i ngā ūnga waikawa karihi i roto i te tauira. Mā te whakauru i ngā tae kanapa, i ngā whakamātautau rānei, ka taea e ngā mīhini huringa wera te ine i te kohikohinga o ngā hua PCR i te wā tūturu, ka whakarato i ngā māramatanga whai hua ki ngā taumata whakaaturanga ira, te kawenga huaketo, me te rerekētanga ira.

3. PCR whakawhiti whakamuri (RT-PCR)

He mea nui te mahi a ngā pūhiko wera i roto i te PCR whakamuri, he tikanga e huri ai te RNA ki te DNA tāpiri (cDNA) hei whakanui ake i muri mai. He mea nui tēnei tikanga mō te ako i te whakaaturanga ira, ngā huaketo RNA, me ngā tauira honohono mRNA. He mea nui te pūhiko wera me te whakahaere pāmahana tika mō te angitu o ngā whakamātautau RT-PCR.

4. PCR mamati

Nā ngā whanaketanga o te hangarau huringa wera kua hua ake te whanaketanga o te PCR mamati, he tikanga tino tairongo mō te ine tino tika o ngā waikawa karihi. Mā te wehewehe i te tauhohenga PCR ki ngā mano o ngā tauhohenga moroiti takitahi, ka taea e ngā huringa wera te whakatau tika i te kukū tuatahi o te ngota ūnga, ka waiho te PCR mamati hei taputapu whai hua mō te kimi i ngā whakarerekētanga onge me te tātari i te rerekētanga o te tau tārua.

5. Te whakarite i ngā whare pukapuka raupapatanga o te whakatupuranga e whai ake nei

He wāhanga nui ngā huringa wera o te tukanga whakarite whare pukapuka mō ngā tono raupapatanga whakatupuranga hou (NGS). Mā te mahi i te whakanui i ngā kongakonga DNA e hangai ana ki te PCR, ka taea e ngā huringa wera te hanga whare pukapuka raupapatanga mai i ngā rauemi tīmatanga iti, e āhei ai ngā kairangahau ki te tātari i te ira katoa o te rauropi, te transcriptome, te epigenome rānei.

6. Te Hangarau Pūmua me te Whakaputa Ira

Haunga te whakanui waikawa karihi, ka whakamahia ngā huringa wera i roto i ngā rangahau hangarau pūmua me ngā rangahau whakaputanga matū. Ko te whakaputanga matū e arotauhia ana e te pae, te arotautanga o te whakaaturanga pūmua, me ngā whakamātautau whanaketanga e arotauhia ana e whakawhirinaki ana ki ngā tikanga e hangai ana ki te PCR, ā, he mea nui ngā huringa wera me te whakahaere pāmahana tika me ngā tere whakamahana me te whakamatao ōrite ki te whiwhi hua tika me te taea te whakaputa anō.

7. Whakamātautau haumaru taiao me te kai

Ka whakamahia hoki ngā mīhini huringa wera i roto i ngā whakamātautau haumaru taiao me te kai, inā koa te kimi i ngā mate huakita moroiti, ngā rauropi kua whakarerekētia te ira (GMO) me ngā mate huakita kai. Mā ngā whakamātautau PCR e whakahaerehia ana i runga i ngā mīhini huringa wera ka taea te tautuhi tere me te motuhake i ngā poke, kia mau ai te haumaru me te kounga o te kai me ngā tauira taiao.

Hei whakarāpopototanga,ngā huringa werahe taputapu tino nui i roto i te koiora ngota me te rangahau ira, e whakarato ana i te whānuitanga o ngā tono i tua atu i te whakanui PCR tuku iho. Nā te maha o ngā whakamahinga me te tika o ēnei mea, he mea nui mō ngā whakamātautau mai i te tātari whakaaturanga ira ki te aroturuki taiao. I te haere tonu o te whanaketanga o te hangarau, tera pea ka nui haere te mahi a ngā huringa wera ki te akiaki i te kitenga pūtaiao me te auahatanga.
