MHC-related protein 1, also known as MR1, is a nonclassical MHC class I molecule highly conserved in mammals, particularly in its α1/α2 domains. MR1 is required for the development and expansion of the mucosal-associated invariant T (MAIT) cells. The transcripts for MR1 are ubiquitously expressed, but its expression on the cell surface seems to be ligand-dependent. MR1 is involved in the presentation of vitamin-derived compounds from bacterial biosynthetic pathways.Product Details

FC - Quality tested
- Recommended Usage
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood.
- Excitation Laser
Blue Laser (488 nm)
Green Laser (532 nm)/Yellow-Green Laser (561 nm)
- Application Notes
Additional reported applications for the relevant formats include: blocking MR1-dependent activation of MAIT hybridomas, clones, or MAIT TCR-transduced cell lines1-6, detection of folded MR1 conformers3,7, and immunoprecipitation of MR1 from cell lysates7.
