IPTG CAS:367-93-1 Kumukūʻai Mea Hana

ʻO Isopropyl β-D-1-thiogalactopyranoside (IPTG) kahi analog synthetic o ka lactose i hoʻohana mau ʻia i ka noiʻi biology molecular a me nā noi biotechnology.Hoʻohana mua ʻia ʻo IPTG e hoʻowalewale i ka hōʻike ʻana o nā genes i loko o nā ʻōnaehana bacteria, kahi e lawelawe ai ma ke ʻano he molecular trigger e hoʻomaka i ka transcription o nā genes target.

Ke hoʻohui ʻia i ka ulu ulu, lawe ʻia ka IPTG e ka bacteria a hiki ke hoʻopaʻa i ka protein repressor lac, e pale ana iā ia mai ka pale ʻana i ka hana o ka lac operon.ʻO ka lac operon he pūʻulu o nā genes i komo i ka lactose metabolism, a i ka wā i wehe ʻia ai ka protein repressor, hōʻike ʻia nā genes.

ʻO Isopropyl β-D-1-thiogalactopyranoside (IPTG) kahi analog synthetic o ka lactose i hoʻohana mau ʻia i ka noiʻi biology molecular a me nā noi biotechnology.Hoʻohana mua ʻia ʻo IPTG e hoʻowalewale i ka hōʻike ʻana o nā genes i loko o nā ʻōnaehana bacteria, kahi e lawelawe ai ma ke ʻano he molecular trigger e hoʻomaka i ka transcription o nā genes target.

Ke hoʻohui ʻia i ka ulu ulu, lawe ʻia ka IPTG e ka bacteria a hiki ke hoʻopaʻa i ka protein repressor lac, e pale ana iā ia mai ka pale ʻana i ka hana o ka lac operon.ʻO ka lac operon he pūʻulu o nā genes i komo i ka lactose metabolism, a i ka wā i wehe ʻia ai ka protein repressor, hōʻike ʻia nā genes.

Hoʻohana pinepine ʻia ka IPTG me ka lacUV5 mutant promoter, ʻo ia ka mana o ka lac promoter.Ma ka hoʻohui ʻana i ka IPTG induction me kēia mea hoʻolaha mutant, hiki i nā mea noiʻi ke hoʻokō i nā kiʻekiʻe kiʻekiʻe o ka hōʻike gene.Hāʻawi kēia i ka hana ʻana i ka nui o ka protein no ka hoʻomaʻemaʻe ʻana a i ʻole nā ​​​​mea hana i lalo.

Ma waho aʻe o ka hōʻike gene, hoʻohana pinepine ʻia ʻo IPTG i nā hōʻike hōʻike ʻulaʻula/keʻokeʻo.Ma kēia ʻano hana, hoʻohui pinepine ʻia ka gene lacZ i kahi moʻo hoihoi, a ʻo nā hua bacteria e hōʻike maikaʻi ana i kēia ʻano hui pū e hoʻoulu i kahi enzyme β-galactosidase ikaika.Ke hoʻohui ʻia ʻo IPTG me kahi substrate chromogenic e like me X-gal, ʻo ka bacteria e hōʻike ana i ka gene fusion e lilo i polū ma muli o ka hana o β-galactosidase.ʻAe kēia i ka ʻike ʻana a me ke koho ʻana i nā kānana recombinant i hoʻohui maikaʻi i ke ʻano o ka hoihoi.

Hoʻohana a me ka hopena

Ka hoʻokomo ʻana i ka ʻōlelo gene: Hoʻohana maʻamau ʻia ka IPTG e hoʻowalewale i ka hōʻike ʻana o nā ʻano genes i loko o nā ʻōnaehana bacteria.Hoʻohālike ia i ka lactose inducer maoli a hoʻopaʻa i ka protein repressor lac, e pale ana iā ia mai ka pale ʻana i ka lac operon.ʻAe kēia i ka unuhi ʻana a me ka hōʻike ʻana i nā genes i makemake ʻia.

Hōʻike protein a me ka hoʻomaʻemaʻe: Hoʻohana pinepine ʻia ka IPTG induction e hana i ka nui o nā protein recombinant no nā kumu like ʻole, e like me ka noiʻi biochemical, hana therapeutic, a i ʻole ka nānā ʻana.Ma ka hoʻohana ʻana i nā vectors hōʻike kūpono a me IPTG induction, hiki i nā mea noiʻi ke hoʻokō i nā kiʻekiʻe kiʻekiʻe o ka hoʻokumu ʻana o ka protein target i nā pūʻali bacterial.

Ka nānā ʻana i ka polū/keʻokeʻo: Hoʻohana pinepine ʻia ʻo IPTG i hui pū me ka gene lacZ a me kahi substrate chromogenic, e like me X-gal, no ka hoʻāʻo ʻana i ka polū/keʻokeʻo.Hoʻohui pinepine ʻia ka gene lacZ i ka moʻo hoihoi, a ʻo ka hua bacteria e hōʻike maikaʻi ana i kēia ʻano hui pū e hoʻoulu i kahi enzyme β-galactosidase ikaika.Ke hoʻohui ʻia ka IPTG a me ka substrate chromogenic, ʻo nā kānana recombinant e hōʻike ana i ka gene fusion e lilo i polū, e ʻae i ka ʻike maʻalahi a me ke koho ʻana.

Ke aʻo ʻana i ka hoʻoponopono gene: Hoʻohana mau ʻia ka IPTG induction i ka noiʻi e aʻo i ka hoʻoponopono ʻana o nā genes a me nā operon, ʻoi aku ka lac operon.Ma ka hoʻopunipuni ʻana i nā manaʻo o IPTG a me ka nānā ʻana i ka hōʻike ʻana o nā ʻāpana lac operon, hiki i nā mea noiʻi ke noiʻi i nā hana o ka hoʻoponopono gene a me ke kuleana o nā ʻano like ʻole a i ʻole nā ​​​​mutations.

Pūnaehana hōʻike Gene: He mea koʻikoʻi ka IPTG i nā ʻōnaehana hōʻike gene, e like me nā ʻōnaehana hoʻolaha T7.I loko o kēia mau ʻōnaehana, hoʻohana pinepine ʻia ka mea hoʻolaha lac e hoʻokele i ka hōʻike o T7 RNA polymerase, ʻo ia hoʻi, e unuhi i nā genes target ma lalo o ka mana o nā kaʻina hoʻolaha T7.Hoʻohana ʻia ʻo IPTG e hoʻowalewale i ka hōʻike ʻana o ka T7 RNA polymerase, e alakaʻi ana i ka hoʻāla ʻana o ka hōʻike gene target.
