  • POLYPEPTIDE DISULFIDE BOND ANALYSIS
    Publication number: 20110151493
    Abstract: The present invention relates in part to methods for determining bonding patterns in disulfide-linked peptides containing closely-spaced cysteine residues. Through N-terminal sequencing chemistry coupled with facile liquid chromatography and mass spectrometric analysis of the cleavage products, one can assign connectivity to specific cysteine pairs. A particular advantage of this method is maintenance of disulfide integrity during the process.

  • Lipoprotein fingerprinting methods using metal ion chelate salts
    Patent number: 7320893
    Abstract: Methods are disclosed which separate and identify lipoproteins in biological samples. An ultracentrifuge density gradient is used to separate lipoprotein fractions. The fractions are visualized, resulting in a lipoprotein profile. The fractions can be further analyzed by a wide array of laboratory and clinical methods. The lipoprotein profile can be used in clinical diagnoses and other medical applications.
