High-dimensional functional phenotyping of preclinical human CAR T cells using mass cytometry

STAR Protoc. 2022 Feb 9;3(1):101174. doi: 10.1016/j.xpro.2022.101174. eCollection 2022 Mar 18.

Abstract

Here, we present a comprehensive protocol for the generation and functional characterization of chimeric antigen receptor (CAR) T cells and their products by mass cytometry in a reproducible and scalable manner. We describe the production of CAR T cells from human peripheral blood mononuclear cells. We then detail a three-step staining protocol with metal-labeled antibodies and the subsequent mass cytometry analysis. This protocol allows simultaneous characterization of CAR T cell intracellular signaling, activation, proliferation, cytokine production, and phenotype in a single assay.
