I-3-NITROPHENYL-BETA-D-GALACTOPYRANOSIDE CAS:3150-25-2

Ukutholwa komsebenzi we-beta-galactosidase: I-ONPG ivame ukusetshenziswa ukuthola ubukhona kanye nomsebenzi we-beta-galactosidase kumasampula ahlukahlukene ebhayoloji, njengezakhi zamagciwane noma ama-lysates eseli. Ukukhiqizwa kwe-o-nitrophenol, enombala ophuzi, kungalinganiswa kalula kusetshenziswa i-spectrophotometer.

Izifundo zokubonakaliswa kwezakhi zofuzo: I-ONPG ivame ukusetshenziswa ocwaningweni lwebhayoloji yama-molecule ukuze kufundwe ukubonakaliswa kwezakhi zofuzo. Ngokuhlanganisa umgqugquzeli wezakhi zofuzo ezithakaselwayo nezakhi zofuzo ezifaka i-beta-galactosidase, abacwaningi bangalinganisa umsebenzi walo mgqugquzeli ngokungeza i-ONPG futhi balinganise ukukhiqizwa kwe-o-nitrophenol okuphumelayo. Le ndlela, eyaziwa ngokuthi i-beta-galactosidase reporter assay, inikeza ulwazi mayelana nomsebenzi wokubhalwa kwezakhi zofuzo.

Ukuhlonza amagciwane: Amanye amagciwane akhiqiza i-beta-galactosidase, kanti amanye awakhiphi. I-ONPG ingasetshenziswa kanye nezinye izivivinyo zamakhemikhali ukuhlonza izinhlobo zamagciwane ngokusekelwe ekhonweni lazo lokumanzisa i-ONPG. Le ndlela ivame ukusetshenziswa emalabhorethri okuxilonga emitholampilo kanye nasezifundweni ze-microbiology.

Ukuhlolwa kwama-enzyme inhibitors noma ama-activator: I-ONPG ingasetshenziswa ukuhlola ama-compound alawula umsebenzi we-beta-galactosidase. Ngokulinganisa umsebenzi we-enzyme lapho kukhona ama-compound ahlukene, abacwaningi bangabona ama-inhibitor noma ama-activator angaba khona angaphenywa kabanzi ukuze kutholakale amandla awo okwelapha.
