In molecular biology, an inducer is a molecule that regulates gene expression. [1] An inducer functions in two ways; namely: By disabling repressors. The gene is expressed because an inducer binds to the repressor. The binding of the inducer to the repressor prevents the repressor from binding to the operator.
An inducer designed for testing in water tunnels. An inducer is the axial inlet portion of a centrifugal pump rotor, the function of which is to raise the inlet head by an amount sufficient to prevent significant cavitation in the following pump stage. [1]
In a ferromagnetic core inductor, when the magnetic field approaches the level at which the core saturates, the inductance will begin to change, it will be a function of the current (). Neglecting losses, the energy W {\displaystyle W} stored by an inductor with a current I 0 {\displaystyle I_{0}} passing through it is equal to the amount of ...
Cysteine-rich angiogenic inducer 61 (CYR61) or CCN family member 1 (CCN1), is a matricellular protein that in humans is encoded by the CYR61 gene. [ 5 ] CYR61 is a secreted, extracellular matrix (ECM)-associated signaling protein of the CCN family ( CCN intercellular signaling protein ).
Once this happens, the gene can be normally transcribed to produce T7 RNA polymerase. T7 RNA polymerase, in turn, can bind to the T7 promoter on the expression vector and begin transcribing its downstream gene of interest. To stimulate this process, the inducer IPTG can be added to the system.
IPTG is an effective inducer of protein expression in the concentration range of 100 μmol/L to 3.0 mmol/L. Typically, a sterile, filtered 1 mol/L solution of IPTG is added 1:1000 to an exponentially growing bacterial culture, to give a final concentration of 1 mmol/L.
Goat Cheese, Pecan, and Mixed Green Salad. This premade salad consists of mixed greens, pecans, dried cranberries, bell peppers, tomatoes, red onions, and goat cheese with a honey vinaigrette. The ...
The lactose operon (lac operon) is an operon required for the transport and metabolism of lactose in E. coli and many other enteric bacteria.Although glucose is the preferred carbon source for most enteric bacteria, the lac operon allows for the effective digestion of lactose when glucose is not available through the activity of β-galactosidase.
