Fig. 2. Analysis of normal donor serum on 409 600 peptide microarray. (a) Cell plot of each peptide array (column) by each peptide (row) where red indicates high binding and blue indicates low binding. (b) Correlation between replicate peptide arrays versus serum dilution. Red indicates high correlation and blue indicates low correlation. (c) The maximum observed signal (red squares), 99.5 percentile (blue circles) and the peptide array median (black circles) for the averaged RFU as a function of serum dilution.
