Patent ID: 7087435

Claim:
A method for diagnosing insulin resistance by determining the presence of a biopolymer marker consisting of amino acid residues 2–25 of SEQ ID NO:1 comprising: (a) conducting mass spectrometric analysis on a sample in a manner effective to maximize analysis of peptide fragments contained therein and comparing a mass spectral profile of said biopolymer marker consisting of amino acid residues 2–25 of SEQ ID NO:1 to mass spectral profiles obtained and analyzed from said sample; and (b) confirming the presence of said biopolymer marker consisting of amino acid residues 2–25 of SEQ ID NO:1 by identifying a mass spectral profile having an ion peak at about 2753 daltons in said sample; wherein the presence of said biopolymer marker consisting of amino acid residues 2–25 of SEQ ID NO:1 is diagnostic for insulin resistance.
