Evaluation of Molecular Species of Prostate-Specific Antigen Complexed with Immunoglobulin M in Prostate Cancer and Benign Prostatic Hyperplasia
Figure 3
Representative spectra of free PSA-immunoreactive species. On-chip chromatography of free PSA was performed using anti-fPSA monoclonal antibody array. The -axis represents the distribution of ions by mass (mass to charge ratio, ) and the -axis shows signal intensity of the ions. M + 2H: double charged form. (a) PCa fPSA (free PSA from PCa sera); (b) BPH fPSA (free PSA from BPH sera).
