The NIH Tetramer Core Facility is pleased to announce that we are now accepting orders for human and mouse MR1 tetramers. Please visit the MR1 order page to complete an official order for your MR1 tetramers. Placing an order there is required, even if you had previously requested to be put on the MR1 distribution list. The order page contains significantly more information about our MR1 tetramer reagents.

MR1 requests are subject to the same review schedule as all other reagent requests. The review schedule for the Tetramer Resource Committee can be found at

All clients of the TCF are required to fill out a new Material Transfer Agreement (MTA).  The MTA can be downloaded at
