^a This table summarizes the characteristics of the HIV-1-infected cell PAR-CLIP libraries, including the total number of assignable (≤1 mismatch) PAR-CLIP reads (column 2), the percentage of PAR-CLIP reads that can be assigned to HIV-1 RNAs (column 3), and the total number of HIV-1 transcripts per cell at the time of cross-linking and RNA harvest (column 4), as determined by qRT-PCR with RNA standards.
