The rhAmpSeq Sample ID Panel consists of 76 unique rhAmp primer pairs in a single tube to amplify corresponding SNP markers for accurate sample tracking and identification in targeted sequencing workflows. These are the same highly polymorphic SNPs that
are used in our xGen Human ID Research Panel and that are capable of identifying a unique individual within
a population of more than 25 million biological samples.
This panel has been tested on genomic DNA (gDNA), FFPE, and cfDNA input samples, and has been optimized for coverage uniformity and on-target specificity, as shown in the Performance section below.
The rhAmpSeq Sample ID Panel provides high discrimination power for worry-free sample tracking to avoid sample swaps or mix-ups during processing. Our computational models below (Table 1) show the probabilities of any 2 samples sharing the same genotypes
across a number of SNP sites (simulated from a Korean population).
Table 1. Calculated chances that any 2 people share genotypes across a given number of sites (out of 71 sites).

The rhAmpSeq Sample ID Panel is compatible with both the regular and high-throughput rhAmpSeq library preparation protocols. Therefore, you can choose the best workflow for each experiment without having to buy different reagents. Table 2 summarizes our
observations regarding the respective performance attributes of each protocol. However, your results may vary—contact Application Support for more information.
