Title: tetramer staining Long Title: IUPAC Gold Book - tetramer staining DOI: 10.1351/goldbook.13730 Status: current Definition Technique used for selective staining of antigen-specific T lymphocytes in vitro or in situ. The antigen is presented to T cells by peptide tetramer constructs of major histocompatibility (MHC) class I molecules. It is also used to isolate antigen-specific T-cell populations for clonal expansion.
