xGen™ Lockdown™ probes are individually synthesized 60–120 nucleotide 5’-biotinylated capture oligonucleotides designed to enable high-depth sequencing and analysis of specific regions of the genome. xGen Lockdown probes work well for target enrichment and custom panel development. Available at three different scales, users can design their initial capture panels using the mini scale and extend them by progressively supplementing with more probes. They are supplied in 96- or 384-well plates, or as pools of up to 2,000 oligos.
