Taw qhia
IPTG yog ib qho kev ua kom muaj zog ntawm β-galactosidase. Raws li tus yam ntxwv no, thaum lub vector DNA ntawm pUC series (los yog lwm yam vector DNA nrog lacZ gene) hloov nrog lacZ tshem tawm hlwb ua tus tswv tsev, lossis thaum lub vector DNA ntawm M13 phage hloov, yog X-gal thiab IPTG ntxiv. mus rau lub phaj nruab nrab, vim yog α-complementarity ntawm β-galactosidase, cov noob recombinant tuaj yeem xaiv tau yooj yim raws li seb cov kab dawb (los yog plaques) tshwm. Tsis tas li ntawd, nws kuj tseem siv tau los ua ib qho kev qhia inducer rau kev qhia vectors nrog cov neeg txhawb nqa xws li lac lossis tac. Soluble hauv dej, methanol, ethanol, soluble hauv acetone, chloroform, insoluble hauv ether. Nws yog ib qho inducer ntawm β-galactosidase thiab β-galactosidase. Nws tsis yog hydrolyzed los ntawm β-galactoside. Nws yog cov tshuaj substrate ntawm thiogalactosyltransferase. Formulated: IPTG yog yaj nyob rau hauv dej, thiab ces sterilized los npaj ib tug cia tov (0 · 1M). Qhov kawg IPTG concentration nyob rau hauv qhov taw qhia phaj yuav tsum yog 0 · 2mM.
