Abstract

Methods and oligonucleotide reagents for analyzing individual T cells are disclosed. In particular, the present disclosure provides methods for analyzing individual T cells using high-throughput multiplex amplification and deep sequencing of nucleic acids encoding T cell receptors (TCRs) and various other T cell phenotypic markers. The present disclosure further provides methods of reconstituting TCRs from individual T cells for functional studies, ligand discovery, or screening therapeutics.

ii) a first set of reverse primers comprising reverse primers that hybridize to a nucleotide sequence encoding a constant region of a T cell receptor, wherein primers from the first set of forward primers and the first set of reverse primers amplify nucleotide sequences encoding T cell receptors, or a portion thereof, and
iii) a first set of phenotypic marker primers comprising one or more primer pairs that hybridize to and amplify nucleotide sequences encoding a phenotypic marker, or a portion thereof;

b) a second container comprising a second set of primers, wherein the second set of primers comprises:
i) a second set of forward primers, wherein each primer in the second set of forward primers comprises a first common sequence, and
ii) a second set of reverse primers, wherein each primer in the second set of reverse primers comprises either a sequence that amplifies a T cell receptor constant region, or a second common sequence; and

c) a third container comprising a third set of primers, wherein the third set of primers comprises:
i) a third set of forward primers that hybridizes to the first common sequence,
ii) a third set of reverse primers comprising a sequence that hybridizes to the T cell receptor constant region, or the second common sequence, wherein the third set of forward and reverse primers collectively comprises nucleotide sequences selected from the group consisting of SEQ ID NOS:225-248 and having a length ranging from 50-60 nucleotides, and
iii) a set of primers comprising an adapter sequence for paired-end sequencing.
