Targeted capture was performed in accordance
with the MYbaits kit protocol (MYcroarray, manual
version 1.3.7). The sample libraries were combined
with the biotinylated RNA baits and left to hybridize
on a thermocycler for approximately 36 h. Following
hybridization, the baited libraries were recovered
with Streptavidin C1 magnetic beads (MyOne),
which attach to the biotinylated beads, and undergo
intensive washing to remove nonhybridized and nonspecifically
hybridized library molecules. Indexing of
samples was performed during post-amplification of
the hybridized samples using NEBNext Multiplex
Oligos index primers (New England Biosciences).
