myBaits Expert — Predesigned Panels
myBaits Expert – Plant – Compositae-1061
This probe set (formerly named CompCOS) enables the rapid sequencing of hundreds of orthologous nuclear loci in the Daisy Family, Compositae (Asteraceae).

myBaits Expert – Plant – Compositae-1061

These probes have been demonstrated to enrich hundreds of single to low-copy protein-coding genes across members of Compositae, both at higher and lower taxonomic levels. Probes were designed from 1061 loci, each with 2 to 3 representative sequences from across the Daisy Family to maximize taxonomic breadth of the design (Mandel et al. 2014).

The baitset is broadly applicable for phylogenetic research across Compositae, as well as, members of its sister family Calyceraceae (Mandel et al. 2017). The baitset is available from Daicel Arbor Biosciences as an in-stock catalog kit available for immediate shipment at a low per-reaction cost. As with all myBaits kits, the Compositae-1061 probe set is provided as a complete solution target capture kit, including buffers, blockers, and baits, along with an easy-to-use protocol. Or if you would prefer to outsource the work, our myReads NGS service expert scientists are available to perform library preparation, target capture, and sequencing for your entire project.

  • Predesigned Panel – Designed by expert plant geneticists
  • Proven results – Demonstrated utility across broad taxonomic range
  • Freely accessible pipelines – Simple, user-friendly data analysis
  • Cost-effective – Use one bait set across multiple distantly-related taxa

myBaits COS Compositae 1Kv1
Kit for enrichment of 1,061 COS loci in the Compositae/Asteraceae plant family. Demonstrated to recover >700 loci across a range of Compositae species and closely-related families.
Available in-stock for immediate shipment.
Please Note

This panel was previously described as “CompCOS 1Kv1” under the UCE line.



This set of 9,678 120mer probes targets 1,061 conserved orthologous set (COS) loci in the Compositae/Asteraceae plant family. These ~10K probes are known to enrich >700 loci across a wide range of Compositae species as well as taxa from closely-related families. The bait list can be downloaded here.
