MHC II Dextramer®
Identify Antigen-specific CD4+ T Cells
Antigen-specific CD4+ T cells play an important role in the immune response of autoimmune disease, cancer, transplantation, infectious disease, and allergy.
MHC II Dextramer® reagents can identify antigen-specific CD4+ T-cell subsets by flow cytometry.
MHC II Dextramer reagents consist of a protein-stabilizing dextran backbone, an optimized number of MHC-peptide complexes, and fluorophores (PE, APC or FITC) or no fluorophore (None).
Immudex manufactures MHC II Dextramer reagents as listed in the table below. Customized reagents are easily made with MHC alleles from our catalog and with peptides that form stable complexes with the MHC molecule.
Detection of DRB1*0101/EBV-specific T cells in blood sample using flow cytometry.
How to Order MHC II Dextramer®
Please send an e-mail to ordering@immudex.com specifying:
- Cat. no or the MHC allele-peptide combination of the MHC II Dextramer reagent.
See our current list of MHC alleles - Fluorophore (PE, APC or FITC) or no Fluorophore (None)
- Test sizes (50, 150, 500, 1000 tests). One test is defined as 10 µl MHC Dextramer reagent, sufficient to stain up to 1-3 x 10^6 lymphoid cells or 1-3 x 10^5 clonal antigen-specific T cells.
