hyRAD

Hybridization RAD for Degraded DNA

hyRAD (Suchan et al., 2016) was developed for use on degraded DNA samples, such as those from museum collections. Museum and preserved samples offer a rich source of valuable specimens, but their degraded DNA is unable to sustain the double-digestion and sample fractionation required by ddRAD (Peterson et al., 2012). To address this limitation, hyRAD uses biotinylated probes and streptavidin-covered beads to capture and enrich the fragments of interest.

The first step in the process is to generate a ddRAD library from high-quality DNA, usually from an extant specimen. The fragments are size-selected and biotinylated. They can now be used as probes for hybridization capture of shotgun or ddRad libraries.

Advantages:

  • Can be used on degraded DNA
  • Can be used on unsequenced genomes

Disadvantages:

  • Coverage not as complete as with high-quality samples


Reagents:
