Abstract

Mass Spectrometry (MS)-based proteomic measurements are uniquely poised to impact the development of cell and gene therapies. With the adoption of rigorous instrumental performance controls (PQs), large-scale proteomics can move from a research to a manufacturing control tool. Especially suited, data-independent acquisition (DIA) approaches have distinctive qualities to extend multi-attribute method (MAM) principles to characterize the proteome of cell therapies. Here we describe the development of a DIA method by SWATH Acquisition for the sensitive identification and quantification of proteins on a Q-TOF instrument. Using the improved acquisition parameters, we defined some control metrics to improve the reproducibility of SWATH Acquisition-based proteomic measurements. Finally, we applied the method to analyze the proteome of Jurkat cells that here serves as a model for human T-cells.
