Peptide affinity towards erythrocytes and PBMC cell membranes.

<p>The dependence of the ratio on the enfuvirtide (red) and T-1249 (blue) concentrations for erythrocytes (A) and PBMC (B) was analyzed by a single binding site model (dashed lines) in order to quantify the dissociation constants (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0009830#pone-0009830-t001" target="_blank">Table 1</a>). Ratio values were normalized for the initial value of zero peptide concentration. Plotted values represent the mean ± SEM (error bars not visible in erythrocytes due to small errors). N = 6 for erythrocytes and N = 7 for PBMC.</p>
