Representative PSA-immunogram of pooled human prostate cancer sera. Sephacryl S-300 gel filtration of pooled human PCa sera. The elution was monitored by measuring IgM-reactivity (---) and PSA-reactivity (—) in selected fractions. Fraction volume was 1 mL; cpm: counts per minute. (a) IgM; (b) PSA-IgM; (c) PSA-ACT (alpha-1-antichymotrypsin); (d) fPSA: free PSA.
