Human tetramers - Class II - BV421

Human tetramers - Class II - BV421

MHC tetramers are complexes of four MHC molecules, associated with a specific peptide and bound to a fluorochrome. Class II tetramers bind to a distinct population of CD4+ T cells.

MHC class II tetramer staining is more technically challenging than class I tetramer staining.

  • Antigen-specific CD4+ T cells are more rare than antigen-specific CD8+ T cells
  • Affinity between the T cell receptor and MHC/peptide complex is generally lower
  • Acquisition of 100,000-200,000 CD4+ T cells is typically required
  • Exclusion gating essential
  • T cell expansion and/or pre-enrichment may be required
MHC tetramers are labeled with fluorescent molecules including phycoerythrin (PE), allophycocyanin (APC), or Brilliant Violet 421 (BV421) and thus allow detection of antigen-specific T cells by flow cytometry or fluorescence microscopy.
