    摘要: Disclosed herein include systems, methods, compositions, and kits for labeling nucleic acid targets in a sample. In some embodiments, nucleic acid targets (e.g., mRNAs) are initially barcoded on the 3' end and are subsequently barcoded on the 5' end following a template switching reaction and intermolecular and/or intramolecular hybridization and extension. 5'- and/or 3'-barcoded nucleic acid targets can serve as templates for amplification reactions and/or random priming and extension reactions to generate a sequencing library. The method can comprise generating a full-length sequence of the nucleic acid target by aligning a plurality of sequencing reads. Immune repertoire profiling methods are also provided in some embodiments.
