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.
Chairs and bar stools are measured in seat height. The height from the floor to the top of the seat. A good rule of thumb is there should be between 9 and 13 between the seat height and the height of the counter or table where the chair or stool is going to be used. 18 inch stools are designed to be used at 30 counter height, table or desk. This stool is commonly used at a bathroom vanity or make-up table. We also supply this height stool to theaters for dressing rooms and to casinos for use in front of the slot machines.
