Background: The Laboratory of Molecular Biology and Immunology, National Institute on Aging (LMBI/NIA) has a need for the dCODE Dextramer® which adds a unique DNA barcode to the MHC Dextramer® reagent to detect antigen-specific T cells by NGS or single-cell multi-omics High-avidity binding to T-cell receptors thanks to multiple MHC-peptide complexes High-throughput screening with a unique barcode for each MHC-peptide specificity Enrichment of low-frequency cells thanks to PE fluorochromes

Compatible with single-cell gene expression analysis

Purpose and Objectives: The purpose of this acquisition is to purchase dCODE

Dextramer®, which is used to provide researchers in the Laboratory of Molecular Biology and Immunology, National Institute on Aging (LMBI/NIA) to add a unique barcode to reagents.

Project requirements: The Contractor shall provide dCODE Dextramer® with the following specifications:
