MHC II Dextramer® – Identify Antigen-Specific CD4+ T Cells

Enhanced Sensitivity for Reliable Results

Typically expressed on the surface of antigen-presenting cells, MHC II molecules dock and primes CD4+ T cells.

Antigen-specific CD4+ T cells are critical for the immune response of many diseases, given their role in recruiting and coordinating other immune cells. Often challenging to detect and stratify with standard reagents, antigen-specific CD4+ T cells are revealed through the high-avidity and enhanced sensitivity of the Dextramer® technology.

With multiple MHC-peptide complexes and fluorophores on a flexible dextran backbone, MHC II Dextramer® reagents are designed for high-resolution characterization of CD4+ T-cell responses, even with low-abundance cells and in complex matrices like blood.

Order MHC II Dextramer®

You can order MHC II Dextramer® reagents in one of three ways:

  1. Use the table below to find and order your MHC II Dextramer® reagent
  2. If you can’t find the reagent to meet your research needs, create a custom reagent
  3. Alternatively, send an e-mail to specifying:
  • Catalog number or desired MHC allele-peptide combination.
         - Consult our lists of available MHC alleles
  • Fluorophore (PE, APC, FITC, or none)
  • Test size (50,150, 500, 1000 tests). One test is 10 µl reagent and sufficient to stain 1–3 x 10^6 lymphoid cells or 1–3 x 10^5 clonal antigen-specific T cells.
