Scatchard analyses of erythropoietin (EPO) binding to its receptor (EPO-R) have shown that some erythroid cells display a biphasic nature of the ligand-saturation curve, indicating the presence of two classes of binding sites with different affinities. The biochemical basis accounting for this observation is unknown. We found that the culture of a human erythroleukemia cell line with tunicamyci...

Differential Pulse Anodic Stripping Voltammetry, DPASV, has been used to monitor the initial stages of grape juice fermentation, focusing on Zn interactions with natural occurring ligands. Langmuir and Scatchard linearization methods have been employed. A 1:1 ratio has been found by either method; from Langmuir data analysis only one ligand population was found, while Scatchard approach gave ri...

Abstract In this work, the adsorption of ciprofloxacin onto yam peel biosorbent was studied by batch method. The equilibrium isotherm analysis process evaluated to provide insight into removal mechanism. A decrease in percentage (75.0 – 60.8%) and an increase capacity (6.0 24.3 mg/g) with concentration from 20 100 mg/L obtained. analyzed Langmuir, Temkin, Freundlich, Scatchard models, best fit ...

The semiempirical theories of mixtures developed by van Laar, Margules, Scatchard-Hamer, Wilson and Renon and Prausnitz are used to study the concentration fluctuations of binary liquid alloys formed among the alkali metals. Examination of the fitting capabilities of these theories leads to the conclusion that those of van Laar, Scatchard-Hamer and Renon and Prausnitz are appropriate both when ...

the charge transfer (ct) complex formation of benzonitrile as acceptor with the aromatic donors o-, m-, p-xylene and ethylbenzene in ccl4 solutions is investigated by chemical shift measurements relative to an external reference. the equilibrium parameters, q and dad of their weak molecular complexes, as found numerically modified cresswel- allred (c-a) method, is compared with graphically scat...

the binding of sodium n-dodecyl sulphate (sds) to aspergillus niger catalase in various ionic strengths at ph 6.4 and a temperature of 27? and 37?c has been studied over a range of sds concentrations using equilibrium dialysis and fluorescence spectroscopy techniques. the binding data were used and interpreted in terms of theoretical models (scatchard equation and wyman binding potential). the ...
