  • Method and product for preparing a protein-containing sample for analysis by mass spectrometry
    Patent number: 11906408
    Abstract: A method for preparing a protein-containing sample for analysis by mass spectrometry includes introducing the sample into a reaction vessel. The reaction vessel contains a reagent mixture including pre-measured quantities of an immobilized proteolytic enzyme, a reducing agent and an alkylating agent. The contents of the reaction vessel are activated by heating or by sonication.
    Type: Grant
    Filed: August 5, 2021
