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.


MHC II Dextramer® detects DRB1*0101/EBV-specific T cells in a blood sample via flow cytometry (internal data).
A Tool For Meticulous And Precise Research
Push the boundaries of your flow cytometry assays with MHC II Dextramer® reagents. Designed for high avidity and exceptional signal-to-noise ratio, MHC II Dextramer® reagents enable you to detect antigen-specific CD4+ T cells with confidence.
- Get the full picture of CD4+ T-cell responses, even the low-affinity ones.
- Ensure consistent, reproducible, and comparable results.
- Expand the limits of your research.
- Secure flexibility in your experiments.
Order MHC II Dextramer®
You can order MHC II Dextramer® reagents in one of three ways:
- Use the table below to find and order your MHC II Dextramer® reagent
- If you can’t find the reagent to meet your research needs, create a custom reagent
- Alternatively, send an e-mail to ordering@immudex.com 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.
