Competitive and noncompetitive reversible binding processes
Physical Review E, 1993This 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.

Competitive Binding Among Oral Streptococci to Hydroxyapatite
Journal of Dental Research, 1977The 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.

Competitive protein-binding radioassay for retinoic acid
Analytical Biochemistry, 1980Rat 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 ...

Receptor conformational change induces fluoride binding despite competitive water binding
Chemical Communications, 2013Fluoride binding by artificial receptors in water remains a challenging task due to the high hydration enthalpy of this anion. A novel cationic boron-based tripodal receptor featuring three flexible ammonium-containing arms has been prepared. NMR spectroscopy studies show that the receptor is capable of binding selectively the fluoride anion with high ...

Modeling binding equilibrium in a competitive estrogen receptor binding assay
Chemosphere, 2007Although 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

Competitive Protein-Binding Assay for 25-Hydroxycholecalciferol
Clinical Science, 19741. A competitive protein-binding assay for plasma 25-hydroxycholecalciferol was developed, using Sephadex LH-20 columns for the isolation of the sterol and a partially purified protein from rat serum as the binding protein. 2. The mean plasma 25-hydroxycholecalciferol in eighteen male and female normal volunteers was 38 ± SD 14 pmol/ml ...

Cefmenoxime and Bilirubin: Competition for Albumin Binding
Pharmacology & Toxicology, 1991Abstract:Certain drugs are known to compete with bilirubin for albumin binding; therefore, all drugs administered to neonates should be tested to determine the degree of competition. The effect of cefmenoxime on bilirubin‐albumin binding was determined by comparing the oxidation rate of free bilirubin in the presence and absence of drug.

Drug competition for intracellular triiodothyronine-binding sites
European Journal of Endocrinology, 1994Barlow JW, Curtis AJ, Raggatt LE, Loidl NM, Topliss DJ. Stockigt JR. Drug competition for intracellular triiodothyronine-binding sites. Eur J Endocrinol 1944;130:417–21. ISSN 0804–4643 A variety of substances, including frusemide, non-esterified fatty acids (NEFAs) and non-steroidal antiinflammatory drugs (NSAIDs), can compete for ...

Measurement of thyroxine by competitive protein binding
Clinica Chimica Acta, 1972Abstract A simplified method is described for the measurement of thyroxine by competitive protein binding, using Sephadex columns for separation of bound from unbound thyroxine. Conditions for the various steps in the method were studied. The results compare well with PBI determinations done on the same subjects.
