Me pēhea te whakatau i te kukū tino pai?
Mō te IPTG (isopropyl-beta-d-thiogalactoside) whakaoho, ka pai ake te kukū teitei ake. Ko te kukū tino pai ka whakawhirinaki ki ngā āhuatanga whakamātautau motuhake me te pānga whakaoho e hiahiatia ana.
Ko te tikanga, ko te kukū o te IPTG e whakamahia ana i waenga i te 0.1-1 mM. Mā ngā kukū iti ka whakaiti i ngā pānga kino ki te tipu o te pūtau, ā, ka taea hoki te whakaiti i te paitini pūtau nā te nui rawa o te whakaputanga o ngā pūmua ūnga. Mā ngā kukū teitei ake ka nui rawa te taumahatanga pākia o te pūtau, ka pā ki te tipu me te whai huatanga o te whakaputanga.
Ko te huarahi ki te whakatau i te kukū tino pai ko te aromatawai i te taumata whakapuakanga o te pūmua ūnga mā te whakahaere i ngā whakamātautau whakaoho IPTG i ngā kukū rerekē. Ka taea te whakahaere i ngā whakamātautau ahurea iti mā te whakamahi i te whānuitanga o ngā kukū IPTG (hei tauira, 0.1 mM, 0.5 mM, 1 mM, me ētahi atu) ā, ka taea te aromatawai i te pānga whakapuakanga i ngā kukū rerekē mā te kimi i te taumata whakapuakanga o te pūmua ūnga (hei tauira, te Western blot, te kitenga fluorescence rānei). E ai ki ngā hua o te whakamātautau, ko te kukū me te pānga whakapuakanga pai rawa atu i tīpakohia hei kukū tino pai.
Hei tāpiritanga, ka taea hoki e koe te tirotiro i ngā tuhinga e tika ana, i ngā wheako rānei o ētahi atu taiwhanga hei mārama ki te awhe kukū IPTG e whakamahia whānuitia ana i raro i ngā āhuatanga whakamātautau ōrite, kātahi ka arotau me te whakarerekē kia rite ki ngā hiahia whakamātautau.
He mea nui kia mōhiotia ko te kukū tino pai ka rerekē pea i runga i ngā pūnaha whakapuakitanga rerekē, ngā pūmua ūnga, me ngā āhuatanga whakamātautau, nō reira he pai ake te arotau i runga i te kaupapa takitahi.
