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.
To fit the counter stool the bar height is about 36 inches but no more than 38 inches. The typical bottom bar does not get higher than 30 inches. The bar counter size with respect to the back bar depth is 24 to 30 inches. The height is no less than 36 inches but no more than 42 inches.
