  • Methods and compositions for mass spectrometry analysis
    Publication number: 20120208295
    Abstract: Methods and compounds are provided to improve the desorption and ionization of analyte for mass spectrometry analysis. More specifically, it is for Electrospray ionization (ESI) mass spectrometry. The method uses charged affinity molecules that can bind with analyte either temporarily or permanently to improve the desorption and ionization of analyte. The charged affinity molecules can be positively charged or negatively charged.

  • MALDI analysis using modified matrices with affinity groups for non-covalent binding with analytes
    Patent number: 8119416
    Abstract: Methods and compounds are provided to improve the desorption and ionization of analyte for mass spectrometry analysis. More specifically, it is for laser desorption/ionization mass spectrometry. The method uses photon energy absorbing molecules that can bind with analyte either temporarily or permanently to improve the desorption and ionization of analyte. The photon energy absorbing molecules can be positively charged or negatively charged.
