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.
Dining height tables are typically around 28-30 high. Therefore, the dining chairs that match these tables usually have a seat that is 16-18 high. However, you can also use shorter backless or swivel stools that measure 18 high. Counter Height: Counter height tables are typically around 35-36 high. Therefore, the counter stools that match these tables are usually in the 24-26 range. Counter height furniture is typically used in casual dining setups, pub sets, and home kitchen islands.
