Mass spec protein quantification
WebSep 9, 2024 · Mass spectrometry (MS)-based proteomics is the most comprehensive approach for the quantitative profiling of proteins, their interactions and modifications. It is a challenging topic as a firm grasp requires expertise in biochemistry for sample preparation, analytical chemistry for instrumentation and computational biology for data analysis. WebElectrospray ionization of a protein often results in generation of multiple charged species of 800 < m/z < 2000 and the resultant spectrum can be deconvoluted to determine the protein's average mass to within 50 ppm …
