As β-galactosidase activity was induced biological activity identification.
Analysis to determine the purity by TLC.

Uses: IPTG is β- galactosidase activity inducing substance. Based on this feature, when the pUC series vector DNA (or other vector with a lacZ gene DNA) deletion in lacZ host cells were transformed with the vector during DNA M13 phage were transfected or, if X is added to the plate medium -gal and of IPTG, since the β- galactosidase α- complementarity, rendering based on whether white colonies (or plaques) are conveniently selected recombinants. In addition, it can be used as the like having a lac or tac promoter expression vector expression inducer.
