If these sites are equivalent and independent, relevant experimental data may be analysed toward the thermodynamic binding constant and the number of binding sites in terms of a linear Scatchard plot
The data were evaluated in the form of a Scatchard plot
, to determine the affinity and binding capacity of the imprinted polymer, expressed by affinity constants (K) and apparent maximum number ([B.sub.max]) of the imprinted polymer sites.
The values of 1/[K.sup.app.sub.d] and [F.sub.max] can be obtained from the slope and the x-intercept of the Scatchard plot
The resulting Scatchard plot
indicated that albumin had 1 high-affinity site and perhaps 2 or more weaker sites (2).

The unchanged structure-activity relations of peptide binding suggest that the detergent did not adversely affect the ligand binding site, but the curvilinear Scatchard plot
does indicate some heterogeneity.

The Scatchard plots
in the absence and the presence of sodium chloride are shown in Figures 11 and 12, and the data of n and K are listed in Table 5.
For higher affinity sites, linear equation is qe/Ce=-0.0159qe+0.2323 (R2= 0.9728), and the values of Kd and qmax, calculated from the slope and intercept of Scatchard plots
, are 62.893mg/L and 14.610 mg/g, respectively.
