Mo te Isopropyl β-d-1-thiogalactopyranoside (IPTG)
Ko te IPTG he tohu allolactose e taea ai te mahi tuhi o te operon lactose, na reira ka taea te whakaputa i nga korero o nga pūmua e rite ana ki nga ira o raro o te operon lactose.
I te nuinga o te wa ka whakamahia te IPTG i roto i nga whakamatautau kati e hiahia ana ki te whakauru i te mahi β-galactosidase. He maha nga wa e whakamahia ana me te X-Gal me te Bluo-Gal mo te tirotiro puru-ma-ma o nga koroni huakita recombinant ka taea te whakaputa i te whakaaturanga o te operon lac i E. coli. Ka herea e te IPTG ki te pūmua repressor lacI me te whakarereke i tona ahua ki te aukati i te aukati o te β-galactosidase whakawaehere ira lacZ.
