Claim 0:
1. A method for identifying apoptosis inhibitor of macrophage (AIM) polypeptides in a sample, the method comprising:
providing a sample comprising immunoglobulins;
immunopurifying IgM immunoglobulins from the sample, wherein the immunopurifying step comprises an elution under conditions suitable to release AIM polypeptides bound to the IgM immunoglobulins into the immunopurified sample;
subjecting the immunopurified sample to a mass spectrometry technique to obtain a mass spectrum of the sample; and
identifying the presence of AIM polypeptides based on the multiply charged ion peaks in the spectrum corresponding to the AIM polypeptides.
