Measurement of thyroxine by competitive protein binding

Clinica Chimica Acta, 1972
Abstract 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.

Determination of calmodulin by competitive binding assay

Analytical Biochemistry, 1986
Calmodulin levels in tissue or cellular extracts can be determined by competition with 125I-calmodulin in a filtration-based direct binding assay. The method is rapid, uses readily available stable components, and possesses a selectivity and sensitivity comparable to that observed with immunoassay and phosphodiesterase activation. This assay provides a

ASSAY OF ALDOSTERONE BY COMPETITIVE PROTEIN BINDING

Acta Endocrinologica, 1970
ABSTRACT We have applied a competitive protein binding technique to the assay of aldosterone, utilizing the aldosterone binding protein (ABP) in kidney as the specific receptor molecule. Intracellular ABP was obtained from the homogenization of adrenalectomized rat kidneys in 0.25 M sucrose.

Competitive Calcium Binding: Implications for Dendritic Calcium Signaling

Journal of Computational Neuroscience, 1998
Action potentials evoke calcium transients in dendrites of neocortical pyramidal neurons with time constants of < 100 ms at physiological temperature. This time period may not be sufficient for inflowing calcium ions to equilibrate with all present Ca2+-binding molecules.

Tuning Porphyrin/DNA Supramolecular Assemblies by Competitive Binding

Journal of the American Chemical Society, 2004
Addition of an intercalating but nonaggregating porphyrin, AuT4, to a preformed adduct between DNA and a strongly aggregating porphyrin, t-H2Pagg, permits control of the extent of aggregation of the latter. The size and the intensity of the ICD and RLS signals depend linearly on the concentration of the intercalating dye and decrease markedly on ...

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

Competitive Ligand-Binding Assay for Measurement of Thyronine-Binding Globulin (TBG)

The Journal of Clinical Endocrinology & Metabolism, 1972
ABSTRACT A competitive ligand-binding assay (CLBA), based on partition of a constant amount of radiolabeled ligand (T3) between thyronine-binding globulin (TBG) and a fixed amount of a rabbit anti-T3, has been utilized to measure serum TBG concentration.

Competitive binding at the noradrenaline storage sites

Irish Journal of Medical Science, 1966
Cocaine, phenoxybenzamine (Dibenzyline) and, less effectively, phentolamine (Regitine) block the chronotropic response (beta-receptor) of tyramine on the isolated guinea-pig’s atria. Phenoxybenzamine induces a persistant blockade, the others a transitory one as they can readily be removed by washing the preparation.
