Figure 2From: Pooling serum samples may lead to loss of potential biomarkers in SELDI-ToF MS proteomic profilingRepresentative SELDI spectra, illustrating a quality control spectrum, 'typical' individual case and control spectra and pooled sample spectra from the case and control groups. For each of the pooled sets, the 20 individual samples in each group were combined to form a pooled sample, from which a spectrum was generated under the same conditions as for individual samples.Back to article page
