| Comments： | APPLICATION: IPTG IS COMMONLY USED IN CLONING PROCEDURES THAT REQUIRE INDUCTION OF BETA-GALACTOSIDASE ACTIVITY. IT IS USED IN CONJUNCTION WITH X-GAL OR BLUO-GAL IN BLUE-WHITE SELECTION OF RECOMBINANT BACTERIAL COLONIES THAT INDUCE EXPRESSION OF THE LAC OPERON IN ESCHERICHIA COLI. IPTG FUNCTIONS BY BINDING TO THE LACI REPRESSOR AND ALTERING ITS CONFORMATION, WHICH PREVENTS THE REPRESSION OF THE BETA-GALACTOSIDASE CODING GENE LACZ ASSAY METHOD: TLC DESCRIPTION: NON-IONIC LOSS: OPTICAL ACTIVITY: [ALPHA]20/D -32.0+/-1.0 DEG, C = 1% IN H2O (DRY MATTER) OTHER NOTES: IPTG IS AN INDUCER OF BETA-GALACTOSIDASE ACTIVITY IN BACTERIA AND IS USED TO DETECT LAC GENE ACTIVITY DURING CLONING EXPERIMENTS OTHER NOTES: NON-METABOLIZABLE GALACTOSE ANALOG STORAGE TEMPERATURE: -20 DEG C WGK: 3 |
