MR1 Dextramer®
For detection of ligand-specific MAIT cells
HLA-E and HLA-G Dextramer®
Identify with NK and T cells with Confidence
Investigate the antigen-specific NK cell Response
HLA-E and HLA-G Dextramer® can be utilized for detecting antigen-specific NK and T cells by understanding their unique peptide recognition and interactions with immune receptors. These molecules offer insights into unconventional T cell responses, immune tolerance, and pathological conditions such as cancer or infectious disease.
Through multimerization of HLA-E or HLA-G, Dextramer® technology increases the avidity for sensitive and reliable detection of NK and T cells.
The HLA-E and HLA-G Product Portfolio
Immudex offers flexibility for researching non-conventional T cells like NK cells. Our range includes biotinylated human HLA-E and HLA-G Monomers, HLA-E and HLA-G dCODE Dextramer® reagents, and HLA-E and HLA-G Dextramer® technology for your preferred assay.
Besides HLA-E and HLA-G Dextramer®, Immudex also provides biotinylated HLA-E and HLA-G Monomers and HLA-E and HLA-G dCODE Dextramer® reagents for detection of antigen-specific NK or T cells by NGS and single-cell multi-omics.
*HLA-E Dextramer® is available also as 15 tests. Larger test sizes of all products are available upon request.

HLA-E Dextramer® successfully stains NK and NKT cells
Here, HLA-E*0103/VMAPRTLIL (UL40) Dextramer® was used to stain NK and NKT cells HLA-A02:01/ALIAPVHAV Dextramer® was used as a negative control. The CMV UL40 protein is a natural ligand for HLA-E.
- NKG2A receptors on NK and NKT cells recognized HLA-E/UL40 and could successfully be detected when using HLA-E CMV UL40 Dextramer®
- The negative control, HLA-A*0201/ALIAPVHAV did not exhibit staining.
