  • a The results of 2 separate experiments are shown for each sample. The results are expressed as the percentage of expected amplifiable DNA calculated for a nondegraded sample (see main text). Rows in boldface correspond to the samples selected for sequencing analysis. ND, no droplets for the cluster.
