Figure 3From: A minimal model of peptide binding predicts ensemble properties of serum antibodiesSimulated signal intensities and assigned amino acid-associated weights are recovered by an amino acid composition-based regression model. (A) Simulated signal intensities ( s → sim ) obtained by amino acid position-dependent simulation of the binding of 150 antibodies to an array of 255 14-mer peptides were predicted using the regression model given by Equation 1. This regression model takes into account only the amino acid composition of the simulated peptide sequences. Predictive performance: Q2 = 0.40. Simulated signal intensities were computed using Equation 2. (B) Equation 1 was used to estimate ( w → sim ), which are shown against the assigned AAWS ( h → ) used to generate the simulated signal intensities s → sim . Coefficient of correlation: r = 0.92.Back to article page
