For information about Morpholino oligos and their delivery systems, you can visit the Gene Tools exhibit at ASCB 2007. Dr. Shannon Knuth and Chandell Terwilliger are expected to be there to chat with folks about applications of Morpholinos, including gene knockdown, splice modification and miRNA blocking.
