Figure 2

Box-plots giving means, errors of means, and standard deviations of ELISA signal intensities from the tumor sera pool (tumor) and the reference sera pool (reference), using equal numbers of antigenic peptides from Meta-UP (UP) and Meta-DOWN (DOWN) proteins. The OD values are ELISA signal readouts. A double asterisk indicates a highly significant difference based on Student's t-test (p = 0.0011).
