Figure 8

Test results from one technical cluster from a biomarker discovery dataset of a mouse preterm labor model. The intensities of six SELDI-TOF MS peaks for term labor and preterm labor are shown in AF. These peaks formed a technical cluster at a variance threshold of 0.3. The cluster centroids for term and preterm labor for this cluster is shown in G. The subsequent ELISA assay results for serum amyloid A2 are shown in H, after identification of candidate biomarker by chromatographic purification, gel purification, and sequencing of tryptic fragments as previously described in the text. Panels A - G are mean ± sem with n = 7 for Term and n = 6 for Preterm. Panel H is mean ± sem with n = 5 for both Term and Preterm.
