Bead-Based Capture Kit Eases Enrichment and Cleanup of DNA Libraries

A newly released bead-based capture system was designed to provide genomic researchers with a sensitive and robust method for capture and purification of DNA sample libraries enabling high-quality targeted sequencing results.

NimbleGen (Madison, WI, USA), the genomics products subsidiary of Roche (Basel, Switzerland), recently announced the global launch of its SeqCap EZ Pure Capture Bead Kit.


This kit offers researchers a set of capture and purification beads used to prevent secondary capture and isolate DNA sample libraries from contaminants during amplification. It, therefore, represents a sensitive and robust method for cleanup of DNA sample libraries for high-quality DNA sequencing results


The kit includes SeqCap EZ Capture Beads and SeqCap EZ Purification Beads. Capture beads are used to recover the captured DNA sample from the hybridization of the DNA sample library and the SeqCap EZ Library. Purification beads are used to purify the amplified DNA sample library and the amplified capture DNA sample library after LM-PCR (ligase mediated - polymerase chain reaction). Roche provides a comprehensive set of reagents and probe pools for superior target enrichment performance. The probe pools include exome libraries, gene panels, and custom designs.

In addition to the SeqCap EZ Capture Beads Kit, Roche NimbleGen has released new disease-specific target enrichment panels for clinical research applications. These include the SeqCap EZ Comprehensive Cancer Design, which covers 578 genes implicated in a wide range of common and rare cancers, and the SeqCap EZ Neurology Panel Design, which covers 256 genes associated with 87 neurological disorders, including Parkinson’s disease, Alzheimer’s disease, epilepsy, and autism.
