MHC I & II Multimers

T cells recognize specific MHC-peptide complex displayed on the surface of antigen-presenting cells. This specific interaction is used by MHC multimers carrying MHC-peptide complexes to detect and isolate antigen-specific T cell. Fluorescent-labeled MHC multimers are used to detect, quantify and isolate antigen-specific T cells in fluid samples (e.g. blood, cultured cell lines, CSF, lymph, synovial fluid) by flow cytometry, and for in situ detection (e.g. in solid tumors) by immunohistochemistry (IHC).

MHC Dextramers®
  • Stabilizing dextran polymer backbone
  • Fluorochrome molecules
  • More MHC-peptide complexes than conventional MHC multimers (such as tetramers)
  • Stronger staining intensity
  • Increased resolution and signal-to-noise ratio
MHC Dextramers detect the presence of antigen-specific T cells whereas interferon-gamma-releasing assays such as ELISpot detect the functionality of the antigen-specific T cells. Thus, a combination of the MHC Dextramer assay and an interferon-gamma-releasing assay, using PepMix™ Peptide Pools as specific stimulating antigens, is an effective tool for reliable and robust immune monitoring!

Applications for MHC I & II Multimers

  • Detection, enumeration and isolation of antigen-specific T cells in fluid cell samples (PBMC, blood) by flow cytometry
  • In vitro staining of tissue sections to visualize antigen-specific T cells
  • Vaccine and immunotherapeutic development
  • Clinical trials
  • Immune monitoring of e.g. transplant patients and HIV/AIDS patients

Benefits of MHC I & II Multimers

  • More sensitive than conventional MHC multimers (important for low-affinity interactions commonly encountered in cancer & autoimmune disease)
  • Very stable
  • Order the related Antigen Peptide together with your MHC Dextramer
  • Customized Dextramers® available upon request
