The class II MHC tetramers listed below are available as biotinylated monomers or as tetramers made with the listed fluorophore options. Requesters will receive approximately 200 micrograms of protein per unit of quantity. For best results with class II tetramers, we strongly recommend APC or PE over other options.

Please note that the reagents listed on this page have been produced by the NIH Tetramer Facility with strict quality control (including gene sequencing, affinity purification, SDS PAGE analysis, and verification of biotinylation by immunoprecipitation), but many have not been confirmed to stain or activate specific T cells.

Some reagents may require you to send peptide to us in order to conduct a custom synthesis via peptide exchange. Once your order is approved, an email approval notification will be issued, including details regarding any peptide that needs to be supplied.
