Targeted TCR amplification from single-cell cDNA libraries

Abstract

Single-cell sequencing of TCR alleles enables determination of T cell specificity. Here we describe a sensitive protocol for targeted amplification of TCR CDR3 regions from single-cell full-length cDNA libraries. By exploiting the specificity of RNase H-dependent PCR (rhPCR), the protocol achieves amplification of TCR alleles and addition of cell barcodes in a single PCR step.
