Binding Effects in Multivalent Gibbs-Donnan Equilibrium
The classical Gibbs-Donnan equilibrium describes excess osmotic pressure associated with confined colloidal charges embedded in an electrolyte solution. In this work, we extend this approach to describe the influence of multivalent ion binding on the equilibrium force acting on a charged rod translocating between two compartments, thereby mimicking ionic effects on force balance during in vitro...
متن کاملLetter: Analysis of hemoglobin aggregation from Gibbs-Donnan equilibrium experiments
Dear Sir: Gary-Bobo and Solomon (1968, 1971) have employed Gibbs-Donnan equilibrium studies in the assessment o f the anomalous osmotic behavior o f the red cell. In these studies, the interpretation was based on thermodynamic equations for ideal solutions. During the course of recent investigations, we have found that it is necessary to consider the nonideal aspects o f concentrated hemoglobin...
متن کاملApplication of Gel Chromatography*
INTRODUCTION The term Gel Chromatography refers to the process of separation of solutes caused by the passage of a solution through a column filled with a porous gel. The dissolved particles may enter the pores fully or partially or they may remain completely excluded. This results in a sorting out of the dissolved particles according to their size, so that the largest particles migrate with th...
متن کاملGel-Filtration Chromatography.
Gel-filtration chromatography is a versatile method that permits the effective separation of biological molecules in high yield. This article describes the basis of the method, the selection of suitable operating conditions, and contrasts typical matrix types. Applications of the technique are described, with references to the scientific literature.
متن کاملQuantitative interrelationship between Gibbs-Donnan equilibrium, osmolality of body fluid compartments, and plasma water sodium concentration.
The presence of negatively charged, impermeant proteins in the plasma space alters the distribution of diffusible ions in the plasma and interstitial fluid (ISF) compartments to preserve electroneutrality. We have derived a new mathematical model to define the quantitative interrelationship between the Gibbs-Donnan equilibrium, the osmolality of body fluid compartments, and the plasma water Na+...
