Compositions and methods for isolating patient-derived antigen-specific T cells include an antigen complex having a polynucleotide barcoded nanoparticle sorting agent complexed with a peptide-loaded streptavidin major histocompatability complex (MHC) tetramer, the barcoding technology allowing for high fidelity screening of a library of the antigen complexes to readily isolate and identify antigen-specific T cells.
用于分离患者来源的抗原特异性 T 细胞的组合物和方法包括抗原复合物,该抗原复合物具有多核苷酸条形码纳米粒子分选剂,并与肽载链霉亲和素主要组织相容性复合物(MHC)四聚体复合物复合,条形码技术允许对抗原复合物库进行高保真筛选,以轻松分离和识别抗原特异性 T 细胞。
