Ask A Scientist: How to Use Antigen-Specific T Cells as a Control for Tetramer Staining

Peptide-MHC tetramer staining is a common practice with both R&D and clinical applications in infectious disease investigations, vaccine development, immunotherapy and autoimmunity research, and transplantation. Experimentally, this method can be used to measure detailed T cell responses and functions. Clinically, peptide-MHC tetramer staining is used to count, track, and phenotype T cells during infections and…
