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 rule of thumb that can vary a bit but should be considered is the height of the seat should be 12 lower than the table. Most tables and desks are 29 -30 high. Placing chairs at about 16 -18 high. Bar height is 42 making most stools around 30 high. So your benches all seem to fit into that chair category of 16 -18 high. The depth would be a design choice rather than comfort if there is no back on it.
