  • Quantitation of insulin-like growth factor-I and insulin-like growth factor-II with high-resolution mass spectrometry
    Patent number: 11953507
    Abstract: Methods are provided for determining the amount of an IGF-I and/or IGF-II protein in a sample using high resolution/high accuracy mass spectrometry. The methods generally comprise enriching an IGF-I and/or IGF-II protein in a sample, ionizing an IGF-I and/or IGF-II protein from the sample to generate IGF-I and/or IGF-II protein ions, and determining the amount of IGF-I and/or IGF-II protein ions with high resolution/high accuracy mass spectrometry.
    Type: Grant
    Filed: September 21, 2022
    Date of Patent: April 9, 2024
    Assignee: Quest Diagnostics Investments Incorporated
    Inventors: Cory Bystrom, Shijun Sheng, Nigel Clarke, Richard Reitz
