Competitive Binding of Aroma Compounds by β-Cyclodextrin

Journal of Agricultural and Food Chemistry, 2001
Retention of six aroma compounds has been studied after dehydration of ternary mixtures of aroma water and beta-cyclodextrin. A maximal retention of a mole of aroma per mole of beta-cyclodextrin has been observed for five of the aroma compounds, whereas retention of benzyl alcohol can be twice as high. Retention of a mixture of aroma compounds has also

Cooperation and competition by RNA-binding proteins in cancer

Seminars in Cancer Biology, 2022
Post-transcriptional regulation of gene expression plays a major role in determining the cellular proteome in health and disease. Post-transcriptional control mechanisms are disrupted in many cancers, contributing to multiple processes of tumorigenesis. RNA-binding proteins (RBPs), the main post-transcriptional regulators, often show altered expression

Competitive and noncompetitive reversible binding processes

Physical Review E, 1993
This work treats many-body aspects in an idealized class of reversible binding problems involving a static binding site with many diffusing point particles. In the noncompetitive limit, where no restriction exists on the number of simultaneously bound particles, the problem reduces to reversible aggregation.

Modeling binding equilibrium in a competitive estrogen receptor binding assay

Chemosphere, 2007
Although the free concentration is more significant in the environmental chemistry and toxicology of receptor-mediated toxicants, few studies have been conducted to use it as a dose-metric. The relative binding affinity of three model endocrine disrupting compounds, diethylstilbestrol (DES), ethynylestradiol (EE2), and bisphenol A (BPA), were evaluated

COMPETITION BY 24,25-DIHYDROXYCHOLECALCIFEROL IN THE COMPETITIVE PROTEIN BINDING RADIOASSAY OF 25-HYDROXYCALCIFEROL

The Journal of Clinical Endocrinology & Metabolism, 1976
24,25-dihydroxycholecalciferol (24,25-(OH)2D3) is equipotent to 25-hydroxycholecalciferol in the displacement of 3H25-OHD3 from rat serum binding sites, and is extracted by the ethanol procedure recommended in non-chromatographic competitive protein binding radioassays for 25-OHD.

Characterizing Ligand-Microtubule Binding by Competition Methods

2007
The knowledge of the thermodynamics and kinetics of drug-microtubule interaction is essential to understand the structure/affinity relationship of a given ligand family. When a ligand does not show an appropriate signal change (absorbance or fluorescence) upon binding, the extensive direct characterization of its binding affinities and kinetic rate ...

Analyzing competitive binding data

2004
Abstract Competitive binding experiments measure the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand. Ideally, the concentration of unlabeled ligand varies over at least six orders of magnitude.

Competitive protein-binding radioassay for retinoic acid

Analytical Biochemistry, 1980
Rat testes cytosol treated by Blue Sepharose was employed in a simple and sensitive method for the determination of retinoic acid in the rat serum, liver, and intestine. The method permits the detection of as little as 3 ng of retinoic acid. The mean concentrations of retinoic acid in normal male rats were 33.5 ng/ml of serum, 624.9 ng/g wet wt of ...

Competitive Binding Among Oral Streptococci to Hydroxyapatite

Journal of Dental Research, 1977
The relative affinity of various oral streptococci for hydroxyapatite (HA) differed widely. Streptococcus mutans affinity for dextran-coated HA was the highest of all the streptococci to any HA coating. S salivarius had the lowest affinity, and S sanguis affinity was higher than S miteor for saliva-coated HA.

Homologous competitive binding curves

2004
Abstract The most common way to determine receptor number ,, nd affinity is to perform a saturation binding experiment, where you vary the concentration of radioligand. An alternative is to keep the radioligand concentration constant, and compete for binding with the same ligand, but not radioactively labeled.
