IPTG is a molecular biology reagent utilized in cloning experiments. This compound is used as a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon.ne advantage of IPTG for in vivo studies is that since it cannot be metabolized by E. coli its concentration remains constant and the rate of expression of lac p/o-controlled genes, IPTG is not a variable in the experiment.
The Ideal Height. The ideal bar stool should be approximately 28 to 30 inches high to match the 42 to 48 inches standard bar height.
The height of the chair should be about 12 inches less than the height of the table. Therefore, chairs at traditional 30-inch tables should measure 18 inches. Bar stool seats are either 24 inches or 30 inches above the ground, depending on the height of the bar-style table.
