ONPG CAS:369-07-3 Kumukūʻai Mea Hana

ʻO ka O-nitrophenyl-β-D-galactopyranoside (ONPG) he substrate synthetic i hoʻohana ʻia i ka biochemical a me ka molecular biology assays e ana i ka hana o ka enzyme β-galactosidase.Hoʻohana maʻamau ia i nā hoʻāʻo e ʻike i ka hōʻike gene i nā ʻōnaehana bacteria, e like me Escherichia coli.ONPG he hui kala ʻole i hoʻokaʻawale ʻia e β-galactosidase, ka hopena i ka hoʻokuʻu ʻana i kahi hui melemele, o-nitrophenol.Hiki ke ana ʻia ka waihoʻoluʻu melemele ma ke ʻano spectrophotometrically, e hāʻawi ana i ke ana pololei ʻole o ka hana enzyme. ʻO ka assay e hoʻohana ana i ka ONPG ʻike pinepine ʻia ʻo ka ONPG assay a he ʻano hoʻohana nui ʻia i ka noiʻi biology molecular e loiloi i nā pae hōʻike o nā genes i mālama ʻia e ka lac operon i loko o nā pūpū bacteria.

Hoʻohana a me ka hopena

ʻO ka hopena o ka ONPG ma ke ʻano he substrate e hoʻokaʻawale ʻia e ka enzyme β-galactosidase, ka hopena o ka hoʻokuʻu ʻana i kahi hua melemele, o-nitrophenol.Hiki ke ana ʻia kēia hoʻololi kala i ka spectrophotometrically, e ʻae ai i ka helu ʻana o ka hana β-galactosidase. ʻO ka noi ʻana o ONPG ka mea nui i ka loiloi o ka hōʻike gene i ka molecular biology a me ka noiʻi microbiology.Hoʻohana maʻamau ia no ke ana ʻana i ka hana β-galactosidase ma ke ʻano he mea hoʻolaha no nā haʻawina hōʻike gene, ʻoi aku ka nui o nā maʻi bacteria e like me E. coli.Hoʻohana pinepine ʻia ka gene lacZ, ka mea e hoʻopili ai i ka β-galactosidase, ma ke ʻano he hōʻailona no ka nānā ʻana i ka hōʻike gene, no ka mea hiki ke hoʻoulu ʻia kona hōʻike ʻana e nā kūlana kikoʻī a i hoʻomalu ʻia e nā mea hoʻolaha kikoʻī. hōʻike gene ma ke ana ʻana i ka hana o β-galactosidase.Hoʻohana nui ʻia kēia assay i nā noi like ʻole, e like me ke aʻo ʻana i ka hana hoʻolaha, hoʻoponopono gene, a me nā pilina protein-protein.Eia hou, hiki ke hoʻohana ʻia no ka hoʻoholo ʻana i nā kinetics enzyme a loiloi i nā hopena o nā hoʻololi a i ʻole ka mālama ʻana i ka hana enzyme.
