Request forms for the NIH Tetramer Core Facility are fully open and we have resumed work on our custom synthesis production queue. The review schedule for new requests is listed on our website's schedule page.

However, our facility is presently operating under stringent social distancing requirements, and our technicians are working in shifts. Given this, please note the following conditions when submitting your order:

  • Reagent production and delivery: Delivery times for all reagents may be longer than prior to the shutdown.
  • Large orders: Generally, Tetramer Core Facility asks our clients to limit orders to approximately 12 reagents in a 12-month period. This policy ensures equitable access to Facility reagents by the biomedical research community. The Tetramer Resource Committee has approved much larger orders in the recent past.  However, in light of the current social distancing requirements, please consider the following:
    • limit the number of reagents requested to approximately 12 in a 12-month period (which includes both line item requests and number of aliquots)
    • if large orders are required, please provide a detailed justification for the large order and prioritize the order into groups of 6-8 line items (including considering limiting the number of aliquots)


We are presently offering premade SARS-CoV-2 MHC reagents. This list of reagents is subject to change as more data is gathered about epitopes for SARS-CoV-2. Check the page occasionally for updated availability. Note that we can only offer small amounts per reagent at this time, to ensure equitable access to the research community.

Thank you for your patience. We know many of you are eager to restart research projects and we will do everything we can to provide your reagents as quickly as possible.
