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.
As a general rule, allow 10 to 13 between the bar stool seat and the bottom of the bar table or counter for ample leg room. For more information, read our article on Bar Stool Height Selection. Remember to consider height of armrests if you choose bar stools with that feature.
