Abstract

Provided herein are methods for generating a mass spectrometry (MS) profile of a sample from a cell composition, such as an engineered cell composition. In some embodiments, the mass spectrometry profile includes data based on one or more mass spectrometry analyses or techniques. Also provided herein are methods for, based on mass spectrometry profiles of one or more samples of such cell compositions: identifying a mass spectrometry (MS) profile of a genetically engineered cell composition comprising immune cells comprising a recombinant receptor by comparison to a reference mass spectrometry profile; characterizing a process for producing genetically engineered cell composition; assessing cell surface proteins of an engineered cell composition; and assessing a process for producing a genetically engineered cell composition.
