The targets containing sm were further tested against a set of dInosine-containing probes: one probe (the Ino18 probe) contained 18 dInosines matching the sm in the 33%9F target, two probes (21Ino_9nt5 0 and 21Ino_9nt3 0 ) contained 21 dInosines positioned as sm leaving a region of matching 9 nt at either the 5 0 or 3 0 end; and one probe (Ino24) contained 24 dInosines in every third base throughout the whole 70-mer probe.
