Early Access: Deeper Analysis of Ligand-Specific MAIT cells with MR1 dCODE Dextramer® Technology

Characterize Ligand-specific MAIT cells down to the Single-cell Level

Next-Generation Sequencing and Single-cell Multi-omics are powerful methods to further characterize ligand-specific mucosal-associated invariant T cells (MAIT) cells adding information on surface protein and gene expression along with TCR sequencing for an improved understanding of their potential.

With an optimized number of MR1-peptide complexes, a high number of fluorophores, and a unique DNA barcode, MR1 dCODE Dextramer® reagents enable a deeper investigation of ligand-specific MAIT cells.

Investigate Functional Responses, Molecular Mechanisms, and Clonal Expansion with MR1 dCODE Dextramer®

Whether MR1 Monomers, MR1 Dextramer® or MR1 dCODE Dextramer® reagents, Immudex offers two ligands, preloaded into the MR1 Monomer:

  • 5-OP-RU is a potent activator of MAIT cells, from the condensation of microbial 5-A-RU with methylglyoxal
  • 6-FP is a photosynthetic breakdown product of folic acid. As it is non-stimulatory for most MAIT cells it can be used as a negative control.

Custom ligand-MR1 can be requested through Custom Solutions and Services.

Push the Limits of Your Research with MR1 dCODE Dextramer® Technology

MR1 dCODE Dextramer® technology provides better research tools to:

  • Understand MAIT cell function. Combined with surface markers and gene expression, investigate ligand specificity with great sensitivity and resolution for a better understanding of MAIT cell ligand recognition, function, and regulation in different stages of for instance cancer
  • Identify new clonotypes. Link ligand recognition to TCR clonotype to identify or track disease specific MAIT cell clonotype development down to a single-cell level in homeostasis, disease, or therapy.
