Abstract
This review summarizes developments in the use of affinity chromatography to characterize biospecific interactions in terms of reaction stoichiometry and equilibrium constant. In that regard, the biospecificity incorporated into the design of the experiment ensures applicability of the method regardless of the sizes of the reacting solutes. By the adoption of different experimental strategies (column chromatography, simple partition equilibrium, solid-phase immunoassay and biosensor technology protocols) quantitatiative affinity chromatography can be used to characterize interactions governed by an extremely broad range of binding affinities. In addition, the link between ligand-binding studies and quantitative affinity chromatography is illustrated by means of partition equilibrium studies of glycolytic enzyme interactions with muscle myofibrils, an exercise which emphasizes that the same theoretical expressions apply to naturally occurring examples of affinity chromatography in the cellular environment.

Abstract
The objective of this review is to summarize developments in the use of quantitative affinity chromatography to determine equilibrium constants for solute interactions of biological interest. Affinity chromatography is an extremely versatile method for characterizing interactions between dissimilar reactants because the biospecificity incorporated into the design of the affinity matrix ensures applicability of the method regardless of the relative sizes of the two reacting solutes. Adoption of different experimental strategies, such as column chromatography, simple partition equilibrium experiments, solid-phase immunoassay, and biosensor technology, has led to a situation whereby affinity chromatography affords a means of characterizing interactions governed by an extremely broad range of binding affinities--relatively weak interactions (binding constants below 10(3) M(-1)) through to interactions with binding constants in excess of 10(9) M(-1). In addition to its important role in solute separation and purification, affinity chromatography thus also possesses considerable potential for investigating the functional roles of the reactants thereby purified.

Abstract
Immobilized metal ion affinity chromatography has shown promise for isolating desired proteins from a mixture based on their affinity for chelated metal ions. Using frontal analysis, the pH dependence of the saturation capacity of chelating Superose matrix for bovine serum albumin (BSA) is examined over a broad pH range. A significant increase in the capacity was observed near the elution pH of BSA (pH 4.5) from a Cu-imminodiacetic acid column. The results of several experiments indicated that this apparently abnormal variation may reflect the low degree of accessibility of a large portion of copper sites inside chelating Superose. In a broader sense, these results suggest that during frontal analysis, the assumption of column saturation based on a plateau in the exit concentration that is almost at the same level as the input concentration could be misleading for highly cross-linked matrices and relatively large sized proteins. That is, the relatively less accessible copper sites may become difficult to be reached due to high levels of protein adsorption in the more accessible regions and thus give the appearance of a plateau in the breakthrough curve prior to complete column saturation. This is likely to be the case at high pH where BSA demonstrates very high affinity for immobilized copper or at high input concentrations where the equilibrium coverage is expected to be high. The results demonstrate that the estimated saturation capacity could be significantly smaller than the actual capacity.

Abstract
This review surveys developments during the past decade in the use of quantitative affinity chromatography as a means of evaluating equilibrium constants for solute-ligand and solute-matrix interactions. Topics include allowance for multivalency of the partitioning solute, removal of the myth that highly substituted affinity matrices are unsuitable for zonal quantitative affinity chromatography, adaptation of the technique to allow characterization of high-affinity interactions and the application of quantitative affinity chromatography theory to the characterization of biospecific adsorption phenomena in cellular systems.

Abstract
Biospecificity is due largely to the formation and dissociation of non-covalent complexes between small molecules and macromolecules, or between two macromolecules. The first part of this review is concerned with the use of such biospecificity in the fractionation and identification of solutes. Major emphasis is given to affinity chromatography, especially in regard to the practical considerations inherent in an experimental situation and to the wide range of specific interactions that can be utilized. The second part of the review considers the quantitative characterization of biospecific complex formation. The merits of frontal gel chromatography, electrophoretic methods and affinity chromatography are discussed, and special consideration is given to the effects of ligand and/or acceptor multivalency because of its relevance to many biospecific interactions. Finally attention is drawn to the feasibility of employing quantitative affinity chromatographic theory for the determination of association constants for antigen-antibody systems by radioimmunoassay and enzyme-linked immunosorbent assay techniques.

Abstract
The interaction of lysozyme, ovalbumin, bovine and pig serum albumins with Cu2+ immobilized on Chelating Sepharose Fast Flow or TSK gel chelate-5PW was studied by frontal analysis at various initial concentrations of these solutes. The chromatographic data so obtained served as a basis for evaluating some relevant affinity chromatography parameters by adapting previously reported equations to this system. The TSK-based adsorbent had lower adsorption capacity for all the model proteins compared to the agarose-based adsorbent, due primarily to its lower porosity which has a marked influence on the accessibility of the immobilized ligand to the proteins. On the other hand, the TSK-based adsorbent offers almost ideal conditions for studying adsorption equilibria under column chromatographic conditions. The adsorption capacity of these adsorbents for the model proteins ranges from about 0.6 to 7 mumol/ml, equivalent to 40-100 mg/ml, of adsorbent. The following equilibrium constants for the interaction of the proteins with immobilized Cu2+ were obtained: lysozyme, 1.8.10(4); ovalbumin, 1.5.0(5); BSA, 1.7.10(5); PSA, 3.7.10(5) and imidazole, 8.10(3) M-1. Despite the comparatively low affinity of imidazole for the adsorbent, it is an effective competing ligand, at comparatively high concentrations, for adsorbed proteins primarily because all adsorption sites are available to it. The results obtained suggest that about 1/3 to 1/2 of the potential adsorption sites on the model proteins are involved in forming coordination complexes with Cu2+ immobilized to covalently bound iminodiacetate groups on insoluble gel matrices.

Abstract
The potential of affinity chromatography for characterizing lectin-carbohydrate interactions is investigated. First, the effect of galactose on the chromatographic behavior of Ricinus communis phytohemagglutinin on Sepharose 4B is used to establish that quantitative affinity chromatography on polysaccharide matrices affords an unequivocal means of characterizing the interactions of lectins with monosaccharides in solution. Second, a method of characterizing lectin-glycoprotein interactions by affinity chromatography is illustrated in an experimental study with Sephadex G-50 as affinity matrix for examination of the interaction between concanavalin A and ovalbumin. Third, although no general solution to the problem of ligand multivalency in quantitative affinity chromatography has been found, an experimental protocol has been devised for the situation in which the partitioning solute (lectin) is univalent.

Abstract
Quantitative expressions are derived for various retention models of the ion-exchange behaviour of multivalent analytes. Their effectiveness as descriptions of experimental results is then tested by application to partition equilibrium studies of the effect of phosphate concentration on the interaction between the three adenosine 5'-phosphates and diethylaminoethylcellulose at pH 4.4. A completely general multi-state model has pointed to quantitative deficiencies in the currently accepted cooperative two-state model, which is, however, superior to a multi-state model devoid of cooperative effects. A similar situation pertains to the ion-exchange behaviour of cytochrome c on carboxymethylcellulose at pH 7.0.

Abstract
In an affinity chromatographic study designed to examine the validity of considering successive interactions between an affinity matrix and a multivalent partitioning solute to be governed by a single intrinsic binding constant, a recycling partition equilibrium procedure has been used to investigate the interaction of horse liver alcohol dehydrogenase with Blue Sepharose in imidazole-chloride buffer, pH 7.5, I = 0.154. A value of 6000 M-1 has been obtained for the initial binding of this bivalent enzyme to matrix, an interaction which leads to a three- to fourfold enhancement of the subsequent interaction of that molecule with Blue Sepharose. Although this evidence of positive cooperativity in the enzyme-matrix interaction points to a deficiency in quantitative affinity chromatography theory based on equivalence and independence of these interactions [L. W. Nichol, L. D. Ward, and D. J. Winzor (1981) Biochemistry 20, 4856-4860], it is shown that such treatment leads to a much better description of the experimental situation than that provided by an alternative analysis based on cooperativity of enzyme-matrix interactions to the extent that only a single enzyme-matrix complex exists [P. Kyprianou and R. J. Yon (1982) Biochem. J. 207, 549-556]. Moreover, since the characterization of solute-ligand interactions by affinity chromatography is shown to be not unduly dependent upon mechanistic correctness of the thermodynamic model used for the solute-matrix interaction, the technique continues to have great potential for quantitative studies of ligand binding.
