Because all rhAmpSeq reagents are compatible with both our regular and high-throughput library preparation protocols, you can choose the best workflow for each experiment without having to buy different reagents. Table 1 shows the features and specifications
common to both rhAmpSeq system protocols.
Table 1. rhAmpSeq system features and specifications.
|Supported protocols||Regular library preparation (10–100 ng)|
High-throughput library preparation (10–50 ng)
|Sample type||Tissue, FFPE, cfDNA
|Insert size||Flexible (50–200 nt)
|Custom panel size||Up to 5000 amplicons per panel|
|Sample indexing capability||96 index sequences (up to 9216 combinations)|
When multiplexing many samples in a single NGS run, we have observed slightly better sample-level coverage uniformity with the regular rhAmpSeq library preparation protocol. Nevertheless, the high-throughput protocol also offers effective genotype calling,
and performs best when read coverage is not limiting (e.g., >500X per target).
In contrast to the regular protocol, the high-throughput protocol saves both overall time and reagent costs by removing a cleanup step and the need to quantify and normalize libraries before combining libraries onto a flow cell. However, your results
may vary—please contact Application Support for more information.
