FITC-Qa-1b/Mouse Qdm (AMAPRTLLL) MHC Tetramer

CAT#: MHC-YF1402

This product is a MHC tetramer of biotinylated peptide/MHC complex composed Qdm-derived peptide of AMAPRTLLL sequence covering 3-11 and Qa-1b molecule. The pMHC tetramer recognizes CD8 T cells and can be used in the MHC tetramer analysis of individual antigen-specific T cells.

Breast cancer biomarkers at key points during disease progression
Useful Qa-1b Qdm Tetramer
This FITC-labeled Qa-1b tetramer loaded with the Qdm peptide AMAPRTLLL was crucial for our NK cell receptor studies. We were able to detect CD94/NKG2A expressing cells that recognize this non-classical MHC molecule.
Breast cancer biomarkers at key points during disease progression
Reliable Non-Classical MHC Tool
We used this reagent to investigate the interaction between Qa-1b and its receptors. The tetramer was stable and provided clear staining in our flow cytometry experiments, helping us understand the regulation of NK and T cell activity.

Q&As

  1. What is the Qdm peptide and its sequence?

    A: Qdm (Qa-1 determinant modifier) is a peptide derived from the leader sequence of certain MHC class I molecules. Its sequence is AMAPRTLLL (residues 3-11) and it binds to the non-classical MHC molecule Qa-1b.

  2. What receptor recognizes the Qa-1b/Qdm complex?

    A: The Qa-1b/Qdm complex is predominantly recognized by the CD94/NKG2A receptor, which is an inhibitory receptor found on NK cells and some CD8 T cells. This tetramer is used to study these interactions.
