Single cell bar-coding for antibody discovery

Abstract

Provided herein are methods and composition for immune repertoire sequencing and single cell barcoding. In some aspects, such methods may comprise steps of: (a) forming a plurality of vessels each comprising a first cell cDNA of a first cell polynucleotide from a single cell and a second cell cDNA of a second cell polynucleotide from the single cell; (b) extending the first cell cDNA that is hybridized to a barcoded polynucleotide comprising a primer binding site sequence and a barcode sequence and a cDNA annealing sequence, or an amplicon thereof; and extending the second cell cDNA that is hybridized to a barcoded polynucleotide comprising a primer binding site sequence and the barcode sequence and a cDNA annealing sequence, or an amplicon thereof; and (c) amplifying the extended first cell cDNA and the extended second cell cDNA with a primer set.
