Claim 0:
1. A method for determining an amount of insulin-like growth factor-II (IGF-II) protein in a sample, the method comprising:
a. ionizing IGF-II in the sample to produce one or more ions detectable by mass sspectrometry;
b. determining the amount of one or more of the ions comprising an ion with a mass-to-charge ratio selected from a group consisting of 934.69±2, 1068.07±2, 1245.92±2, and 1494.89±2 by mass spectrometry; and
c. determining the amount of the IGF-II in the sample using the amount of the one or more ions determined in step b.
