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.
Counter height stool seats range from 24-29 inches from the floor and are perfect for kitchen counters or tables that are about 34-39 inches high. A bar stool seat is about 30-36 inches from the ground and is perfect for counters or bars that are 40-46 inches from the ground.
