Description

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.

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 ≤0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

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.
