Figure 4

Heat-map representation of ELISA signal intensities for the 12 most reactive epitopes of 12 individual proteins screened with 20 individual ovarian cancer patient sera. Signals are color coded for the interval [-1,1] and represent the log₂-transformed differences between the ELISA signals using tumor serum and signals derived using a control peptide as a background reference. Red coloring indicates increased reactivity of an individual tumor serum.
