Bait expressed and purified in baculovirus-Sf9 cell system.

Prey derived from in vitro transcription of random primed genomic DNA PCR products.

B52-bound RNA was isolated by six rounds of SELEX and cDNAs were cloned.B52-bound RNA was isolated by six rounds of SELEX and cDNAs were cloned.

SELEX clones that mapped to the intron-containing genes were reported and further characterized.
