The method of sample acquisition can be refined to avoid unnecessary collection of inhibitors. For example, in forensics, swab-transfer of blood on fabric or saliva on food, may prevent or reduce contamination with inhibitors present in the fabric or food.
Enzyme inhibition can refer to the inhibition of the expression of the enzyme by another molecule; interference at the enzyme-level, basically with how the enzyme works. This can be competitive inhibition, uncompetitive inhibition, non-competitive inhibition or partially competitive inhibition.
Tandem affinity purification (TAP) method allows high throughput identification of protein interactions. In contrast to yeast two-hybrid approach the accuracy of the method can be compared to those of small-scale experiments [7] and the interactions are detected within the correct cellular environment as by co-immunoprecipitation. However, the ...

Same-excess experiments probing catalyst deactivation and product inhibition are among the most widely used applications of reaction progress kinetic analysis. Among the numerous examples in the literature, some include investigation of the amino alcohol-catalyzed zinc alkylation of aldehydes, [21] the amido-thiourea catalyzed asymmetric ...
[2] [3] Using Henri's methods, Michaelis and Menten nearly perfected this concept of initial-rate method for steady-state experiments. They were studying inhibition when they found that non-competitive (mixed) inhibition is characterized by its effect on k cat (catalyst rate) while competitive is characterized by its effect on velocity (V).

Whereas the IC 50 value for a compound may vary between experiments depending on experimental conditions, (e.g. substrate and enzyme concentrations) the K i is an absolute value. K i is the inhibition constant for a drug; the concentration of competing ligand in a competition assay which would occupy 50% of the receptors if no ligand were present.
The toeprinting assay, also known as the primer extension inhibition assay, [1] is a method used in molecular biology that allows one to examine the interactions between messenger RNA and ribosomes or RNA-binding proteins. [2] It is different from the more commonly used DNA footprinting assay. The toeprinting assay has been utilized to examine ...
