MHC-Multimers for reproducible detection, enumeration and isolation of antigen-specific T cells with disease specific peptides. JPT’s MHC-Multimers are Dextramers® that show a stronger staining intensity, high resolution and good 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. A combination of the MHC Dextramer assay and a functional assay, using PepMix™ Peptide Pools is a strong tool for reliable and robust immune monitoring!
