Validation and identification of serum PF-4. Serum was harvested from Lady mice receiving either a standard diet (black) (n = 10) or a E/S/L-supplemented diet (red) (n = 10) at the study endpoint (37 weeks). A standard comparison was made using the SELDI-ToF biomarker discovery method. A spectral readout from SELDI-ToF MS between the two groups is presented here in gel-view format with a specific emphasis on the banding pattern related to the peptide candidate with an apparent molecular weight of 8960 Da.
