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 standard bar height from the floor to the top of a bar top (excluding the bar rail) should be 42â. This allows for a standard 30â high bar stool to seat you comfortably at your bar. The 12â difference between the seat height and bar top is common in most applications including breakfast bars where the top is 36â high using a 24â bar stool and table or desk height which is 30â using a 18â chair height.
