Early Access: MR1 Monomers

High-quality, ready-to-use MR1 Monomers for flexible investigation of ligand-specific MAIT cells

Producing stable, soluble MR1 Monomers with correct folding is challenging due to their complex structure and low-affinity ligands.

By relying on more than 10 years of experience in protein expression, our team of experts has set up an effective manufacturing process with stringent quality control, providing you with high-quality MR1 Monomers.

Characterize and Investigate MAIT cells with MR1 Monomers

Whether MR1 Monomers, MR1 Dextramer® or MR1 dCODE Dextramer® reagents, Immudex offers two ligands, preloaded into the MR1 Monomer for investigation of ligand-specific mucosal-associated invariant T (MAIT) cells:

  • 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.

The MR1 Product Portfolio

Besides ready-to-use 5-OP-RU and 6-FP Monomers, Immudex also provides MR1 Dextramer® and MR1 dCODE Dextramer® reagents for detection of ligand-specific MAIT cells by flow cytometry, in situ, NGS, and single-cell multi-omics.
